Introduction
Important safety information
It is most important this instruction book be retained with the appliance
for future reference.These warning have been provided in the interest of
safety.You MUST read them carefully before using the appliance. If you are
unsure of the meanings of these warnings contact the John Lewis branch
from which you purchased the appliance.
Safety tips
Follow safety rules and prevent hazardous situations: 1) Use smoking
materials properly. Never smoke in bed. 2) Keep matches or lighters away
from children; 3) Store flammable materials in proper containers; 4) Keep
electrical appliances in good condition and don’t overload mains circuits;
5) Keep cookers, barbecue grills, fireplaces and chimneys grease- and
debris-free; 6) Never leave anything heating on the cooker unattended;
7) Keep portable heaters and open flames, like candles, away from
flamma-
ble materials; 8) Don’t let rubbish accumulate.
Keep alarms clean, and test them weekly. Replace alarms immediately if
they are not working properly. Smoke Alarms that do not work cannot
alert you to a fire. Keep at least one working fire extinguisher on every
floor, and an additional one in the kitchen along with a fire blanket. Have
fire escape ladders or other reliable means of escape from an upper floor
in case stairs are blocked.
Basic safety information
• Dangers,Warnings, and Cautions alert you to important operating
instructions or to potentially hazardous situations. Pay special
attention to these items.
• This Smoke/CO Alarm is approved for use in single-family
residences. It is NOT designed for boat or caravan use.
• This combination Smoke/Carbon Monoxide Alarm has two separate
alarms.The CO Alarm is not designed to de
tect fire or any other gas.
It will only indicate the presence of carbon monoxide gas at the sen-
sor. Carbon monoxide gas may be present in other areas.The Smoke
Alarm will only indicate the presence of smoke that reaches the sen-
sor.The Smoke Alarm is not designed to sense gas, heat or flames.
• This Smoke/CO Alarm cannot operate without working batteries.
Removing the batteries for any reason, or failing to replace the
batteries at the end of their service life, removes your protection.
• NEVER ignore any alarm. See “If Your Smoke/CO Alarm Sounds”
for more information on how to respond to an alarm. Failure to
respond can result in injury or death.
• The Silence Feature is for your convenience only and will not correct a
Smoke/CO problem.Always check your home for a potential problem
after any alarm. Failure to do so can result in injury or death.
• Test this Smoke/CO Alarm once a week. If the Alarm ever fails
to test correctly, have it replaced immediately! If the Alarm is not
working properly, it cannot alert you to a problem.
• This product is intended for use in ordinary indoor locations of family
living units. It is not designed to measure CO levels in compliance with
Occupational Safety and Health Administration (OSHA) commercial or
industrial standards. Individuals with medical conditions that may make
them more sensitive to carbon monoxide may consider using warning
devices which provide audible and visual signals for carbon monoxide
concentrations under 30 ppm. For a
dditional information on carbon
monoxide and your medical condition contact your GP.
• Do not install the Alarm where it may be exposed to dripping water
or could be splashed.

What you need to know about CO
What is CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels do not
burn completely, or are exposed to heat (usually fire). Electrical appliances
typically do not produce CO.
These fuels include:Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly
maintained, are improperly ventilated, or malfunction, CO levels can rise
quickly. CO is a real danger now that homes are more energy efficient.
“Air-tight” homes with added insulation, sealed windows, and other
weatherproofing can “trap” CO inside.
Symptoms of CO poisoning
The following symptoms are related to CARBON MONOXIDE POISONING
and are to be discussed with ALL members of the household:
Fuel-burning appliances like: portable heater, gas or wood burning fireplace,
gas kitchen range or cooktop, gas clothes dryer.
Damaged or
insufficient venting: corroded or disconnected water heater
vent pipe, leaking chimney pipe or flue, or cracked heat exchanger, blocked
or clogged chimney opening.
Improper use of appliance/device: operating a barbecue grill or vehicle in
an enclosed area (like a garage or screened porch).
Transient CO Problems:“transient” or on-again-off-again CO problems
can be caused by outdoor conditions and other special circumstances.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances caused by
outdoor conditions such as:
• Wind direction and/or velocity, including high, gusty winds.
Heavy air in the vent pipes (cold/humid air with extended periods
between cycles).
• Negative pressure differential resulting from the use of exhaust fans.
• Several appliances running at the same time competing for limited
fresh air.
• Vent pipe connections vibrating loose from clothes dryers, boilers,
or water heaters.
• Obstructions in or unconventional vent pipe designs which can
amplify the above situations.
2. Extended operation
of unvented fuel burning devices (range, oven,
fireplace).
3. Temperature inversions, which can trap exhaust close to the ground.
4. Car idling in an open or closed attached garage, or near a home
.
These conditions are dangerous because they can trap exhaust in your
home. Since these conditions can come and go, they are also hard to
recreate during a CO investigation.
How can I protect my family from CO poisoning?
A CO Alarm is an excellent means of protection. It monitors the air and
sounds a loud alarm before Carbon Monoxide levels become threatening
for average, healthy adults.
A CO Alarm is not a substitute for proper maintenance of home appliances.
To help prevent CO problems and reduce the risk of CO poisoning:
• Clean chimneys and flues yearly. Keep them free of debris, leaves,
and nests for proper air flow.Also, have a professional check for
rust and corrosion, cracks, or separations.These conditions can
p
revent proper air movement and cause backdrafting. Never “cap”
or cover a chimney in any way that would block air flow.
• Test and maintain all fuel-burning equipment annually. In the case
of gas appliances, this must be a CORGI registered installer. Many
local gas or oil companies and heating companies offer appliance
maintenance and inspection contracts.When service technicians/
engineers come to service your heating and cooking appliances,
ensure the following checks are carried out if you are unable to do
them yourself.
• Make regular visual inspections of all fuel-burning appliances. Check
appliances for excessive rust and scaling.Also check the flame on
the burner and pilot lights.The flame should be blue.A yellow flame
means fuel is not being burned completely and CO may be present.
Keep the blower door on the boiler closed. Use vents or fans when
they are available on all fuel-burning appliances. Make sure appli-
ances are vented to the outside. Do not grill or barbecue indoors,
or in garages or
on screen porches.
• Check for exhaust backflow from CO sources. Check the draft
hood on an operating boiler for a backdraft. Look for cracks on
boiler heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO is
escaping into your home, open a window or a door. Opening win-
dows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read this manual
in its entirety, and make sure you understand what to do if your CO Alarm
sounds.
Regulatory information for smoke/CO alarms
Regulatory information for CO alarms
What levels of CO cause an alarm?
Underwriters Laboratories Inc. Standard UL2034 requires residential CO
Alarms to sound when exposed to levels of CO and exposure times as
described below.They
are measured in parts per million (ppm) of CO over
time (in minutes).
UL2034 Required Alarm Points*:
• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM
BETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM
BETWEEN 10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM
BETWEEN 60 and 240 MINUTES.
* Approximately 10% COHb exposure at levels of 10% to 95% Relative
Humidity (RH).
The unit is designed not to alarm when exposed to a constant level of 30
ppm for 30 days.
CO Alarms are designed to alarm before there is an immediate life threat.
Since you cannot see or smell CO, never assume it’s not present.
• An exposure to 100 ppm of CO for 20 minutes may not affect average,
healthy adults, but after 4 hours the same level may cause headaches.
• An exposure to 400 ppm of CO may cause headaches in average,
healthy adults after 35 minutes, but can cause death after 2 hours.
This CO Alarm measures exposure to CO over time. It alarms if CO
levels are extremely high in a short period of time, or if CO levels reach
a certain minimum over a long period of time.The CO Alarm generally
sounds an alarm before the onset of symptoms in average, healthy adults.
Continued...
Regulatory information for CO alarms, continued
Why is this important? Because you need to be warned of a potential CO
problem while you can still react in time. In many reported cases of CO
exposure, victims may be aware that they are not feeling well, but become
disoriented and can no longer react well enough to exit the building or
get help.Also, young children and pets may be the first affected.
The average healthy adult might not feel any symptoms when the CO
Alarm sounds. However, people with cardiac or respiratory problems,
infants, unborn babies, pregnant mothers, or elderly people can be more
quickly and severely affected by CO. If you experience even mild symptoms
of CO poisoning, consult a doctor immediately!
Standards: Underwriters Laboratories Inc. Single and Multiple Station
arbon monoxide alarms UL2034.
According to Underwriters Laboratories Inc. UL2034, Section 1-1.2:
“Carbon monoxide alarms cove
red by these requirements are intended to
respond to the presence of carbon monoxide from sources such as, but
not limited to, exhaust from internal-combustion engines, abnormal opera-
tion of fuel-fired appliances, and fireplaces. CO Alarms are intended to
alarm at carbon monoxide levels below those that could cause a loss of
ability to react to the dangers of Carbon Monoxide exposure.” This CO
Alarm monitors the air at the Alarm, and is designed to alarm before CO
levels become life threatening.This allows you precious time to leave the
house and correct the problem.This is only possible if Alarms are located,
installed, and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges:The CO
Alarm is not formulated to detect CO levels below 30 ppm typically. UL
tested for false alarm resistance to Methane (500 ppm), Butane (300 ppm),
Heptane (500 ppm), Ethyl Acetate (200 ppm), Isopropyl Alcohol (200 ppm)
and Carbon Dioxide
(5000 ppm).Values measure gas and vapor concen-
trations in parts per million.
Audible Alarm: 85 dB minimum at 3 metres (10 feet).

The smoke alarm component of this product conforms to regulatory
requirements, including UL217 and is designed to detect particles of
combustion. Smoke particles of varying number and size are produced in
all fires.
Ionization technology is generally more sensitive than photoelectric
technology at detecting small particles, which tend to be produced
in greater amounts by flaming fires, which consume combustible
materials rapidly and spread quickly. Sources of these fires may include
paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization
technology at detecting large particles, which tend to be produced
in greater amounts by smoldering fires, which may smolder for
hours before bursting into flame. Sources of these fires may include
cigarettes burning in couches or bedding.
For your records, please record:
Date Purchased __________ Where Purchased ___________________
This Smoke/CO Alarm is intended for residential use. It is not intended
for use in industrial applications where Occupational Safety and Health
Administration (OSHA) requirements for Carbon Monoxide Alarms must
be met.The Smoke Alarm portion of this device is not intended to alert
hearing impaired residents. Special purpose Smoke Alarms should be
installed for hearing impaired residents (CO Alarms are not yet available
for the hearing impaired).
Smoke/CO Alarms may not waken all individuals. Practice the escape plan
at least twice a year, making sure that everyone is involved – from kids to
grandparents.Allow children to master fire escape planning and practice
before holding a fire drill at night when they are sleeping. If children or
others do not readily waken to the sound of the Smoke/CO Alarm, or if
there are infants or family members with mobility limitations, make sure
that someone is assigned to assist them in fire drill
and in the event of
an emergency. It is recommended that you hold a fire drill while family
members are sleeping in order to determine their response to the sound
of the Smoke/CO Alarm while sleeping and to determine whether they
may need assistance in the event of an emergency.
Smoke/CO Alarms cannot work without power. Battery operated units
cannot work if the batteries are missing, disconnected or dead, if the wrong
type of batteries are used, or if the batteries are not installed correctly.
AC units cannot work if the AC power is cut off for any reason (open fuse
or circuit breaker, failure along an electrical main or at a power station,
electrical fire that burns the electrical wires, etc.). If you are concerned
about the limitations of battery or AC power, install both types of units.
Smoke/CO Alarms cannot sense smoke or CO that does not reach the
sensors. Smoke or CO from fires
in chimneys or walls, on roofs, or on the
other side of closed doors may not reach the sensing chamber and set off
the alarm.That is why one unit should be installed inside each bedroom or
sleeping area—especially if bedroom or sleeping area doors are closed at
night—and in the hallway between them.
Smoke/CO Alarms may not detect smoke or CO on another floor or area
of the home. For example, a stand-alone unit on the second floor may not
detect smoke from a ground floor fire until the fire spreads.This may not
give you enough time to escape safely.That is why recommended minimum
protection is at least one unit in all circulation spaces (normally hallways
and staircases) that form part of escape routes, on every level, and in all
rooms and areas that present a high risk. Even with a unit on every floor,
stand-alone units may not provide as
much protection as interconnected
units, especially if the fire starts in a remote area. Some safety experts rec-
ommend installing interconnected mains (AC) powered units with battery
(DC) back-up (see “About Smoke Alarms”) or professional fire detection
systems, so if one unit senses smoke or CO, all units alarm. Interconnected
units may provide earlier warning than stand-alone units since all units
alarm when one detects smoke or CO.
Smoke/CO Alarms may not be heard.Though the alarm horn in this unit
meets or exceeds current Standards, it may not be heard if: 1) the unit is
located outside a closed or partially closed door, 2) residents recently
consumed alcohol or drugs, 3) the alarm is drowned out by noise from
stereo,TV, traffic, air conditioner o
r other appliances, 4) residents are hear-
ing impaired or sound sleepers. Special purpose units, like those with visual
and audible alarms, etc. should be installed for hearing impaired residents.
Smoke/CO Alarms are not foolproof. Like any electronic device, Smoke/CO
Alarms are made of components that can wear out or fail at any time.
You must test the unit weekly to ensure your continued protection.
Smoke/CO Alarms cannot prevent or extinguish fires.They are not a
substitute for property or life insurance.
Smoke/CO Alarms have a limited life.The unit should be replaced
immediately if it is not operating properly. Smoke alarms are not to be
used with detector guards unless the combination has been evaluated and
found suitable for that purpose. Write the purchase date on the user’s
manual and keep in a safe place for future reference.
Instruction manual
HOW TO INSTALL THIS ALARM
This combination Smoke/CO Alarm was designed to be mounted on the
ceiling or wall. It is not a tabletop device.You must install this device on
the ceiling or wall as outlined below. Read “Where To Install This Alarm”
before starting.
Tools you will need: pencil, drill with 5mm (3/16”) drill bit,
flathead screwdriver, hammer.
•
Do not connect this unit to any other alarm or auxiliary device. It is a
single-station unit that cannot be linked to other devices. Connecting
anything else to this unit may prevent it from working properly.
• Do not install this unit over mains cables or holes into the ceiling.
Air currents will prevent smoke from reaching the sensing chamber
and prevent the unit from alarming. Only AC powered units are
intended for installation over mains cables.
If you want to lock the battery compartment, or lock the Smoke/CO
Alarm to the mounting bracket
, please read the “Optional Locking
Features” section.
1. Hold base firmly and twist the mounting bracket counterclockwise
(left) to separate it from the unit.
2. Hold the mounting bracket against the ceiling (or wall) so the vertical
mounting slot is aligned in the 12 o’clock position and trace around
the inside of the mounting slots (vertical and horizontal mounting).
3. Put the unit where it won’t get covered with dust when you drill the
mounting holes.
4. Using a 5 mm (3/16-inch) drill bit, drill a hole through each pencil mark.
5. Insert the plastic screw anchors into the holes.Tap the screw anchors
gently with a hammer, if necessary, until they are flush with the ceiling
or wall.
6. Line the mounting bracket up over the plastic screw anchors.
7. Screw the mounting bracket to the ceiling or wall through the mount-
ing slots using the two screws provided.
8. Before attaching the
Alarm to
the bracket, insert the two (2)
AA batteries (included) into the
battery compartment. Match
the terminals on the end of the
battery with the terminals on
the unit. Match “+” to “+” and
“-” to “-.” If the batteries are not
fully inserted, the unit cannot
receive battery power.
NOTE:The unit may beep briefly when you install the batteries.This is
normal.The GREEN Light flashes about every 60 seconds when the
unit is receiving battery power.
The battery door will resist closing unless batteries are installed.This
warns you the unit will not operate without batteries.
9. Attach the Smoke/CO Alarm to the
mounting bracket. Line up the guides on
the alarm’s base with the guides on the
mounting bracket.When guides are
lined up, turn the base clockwise (right)
until it snaps into place.
NOTE: Once the Smoke/CO Alarm is
snapped onto the mounting bracket,
you can rotate the Smoke/CO Alarm
to adjust the alignment.
10. Test the Smoke/CO Alarm. See “Weekly
Testing” f
or details.
If the CO alarm sounds
Actuation of your CO Alarm indicates the presence of carbon monoxide
(CO) which can kill you. In other words, when your CO Alarm sounds,
you must not ignore it!
If the CO alarm signal sounds:
1. Operate the Test/Silence button.
2. Call your emergency services or Fire Brigade (like 999 in the UK or
112 in Europe).Write down the number of your local emergency
service here:
_________________________________________________________
3. Immediately move to fresh air—outdoors or by an open door or win-
dow. Do a head count to check that all persons are accounted for. Do
not re-enter the premises, or move away from the open door or win-
dow until the emergency services responder has arrived, the premises
have been aired out, and your CO Alarm remains in its normal condition.
4. After following steps 1-3, if your CO Alarm reactivates within a 24-hour
period, repeat steps 1-3 and call a qualified appliance technician to
investigate for sources of CO from fuel-burning equipment and appli-
ances, and inspect for proper operation of this equipment. If problems
are identified during this inspection have the equipment serviced
immediately. Note any combustion equipment not inspected by the
technician, and consult the manufacturers’ instructions, or contact the
manufacturers directly, for more information about CO safety and this
equipment. Make sure that motor vehicles are not, and have not, been
operating in an attached garage or adjacent to the residence.Write
down the number of a qualified appliance technician here:
_________________________________________________________
“ALARM-MOVE TO FRESH AIR”
If you hear the alarm horn sound 4 beeps, pause, 4 beeps, pause and the
RED CO light is flashing, move everyone to a source of fresh air.
If the smoke alarm sounds
Responding to an alarm
• If the unit alarms and you are not testing the unit, it is warning you
of a potentially dangerous situation that requires your immediate
attention. NEVER ignore any alarm. Ignoring the alarm may result in
injury or death.
• Never remove the batteries from a battery operated Smoke/CO
Alarm to stop an unwanted alarm (caused by cooking smoke, etc.).
Removing batteries disables the alarm so it cannot sense smoke,
and removes your protection. Instead open a window or fan the
smoke away from the unit.The alarm will reset automatically.
• If the unit alarms get everyone out of the house immediately.
What to do in case of fire
• Don’t panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don’t stop to get
dressed or collect anything.
• Feel doors with the back of your hand before opening them.
If a door is cool, open it slowly.
Don’t open a hot door. Keep doors
and windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp).
Take short, shallow breaths.
• Meet at your planned meeting place outside your home,
and do a head count to make sure everybody got out safely.
• Call the Fire Brigade as soon as possible from outside.
Give your address, then your name.
• Never go back inside a burning building for any reason.
• Contact your Fire Brigade for ideas on making your home safer.
Alarms have various limitations. See "General Limitations of Smoke/CO
Alarms" for details.
Using the silence feature
Never remove the batteries to quiet an unwanted alarm. Removing the
batteries disables the alarm and removes your protection.
The Silence Feature is intended to temporarily silence the horn while you
identify and correct the problem. Do not use the Silence Feature in emer-
gency situations. It will not correct a CO problem or extinguish a fire.
To use the Silence Feature, press and hold the Test/Silence button on the
cover of the Smoke/CO Alarm for 3 seconds.
Regular maintenance
This unit has been designed to be as maintenance-free as possible, but
there are a few simple things you must do to keep it working properly.
Use only the replacement batteries listed below.The unit may not operate
properly with other batteries. Never use rechargeable batteries since they
may not provide a constant charge.
• Test it at least once a week.
• Clean the Smoke/CO Alarm at least once a month; gently vacuum the
outside of the Smoke/CO Alarm using your household vacuum’s soft
brush attachment.A can of clean compressed air (sold at computer or
office supply stores) may also be used. Follow manufacturer instructions
for use.Test the Smoke/CO Alarm. Never use water, cleaners or
solvents since they may damage the unit.
• If the Smoke/CO Alarm becomes contaminated by excessive dirt, dust
and/or grime, and cannot be cleaned to avoid unwanted alarms, replace
the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where
This Alarm Should Not Be Installed” for details.
Choosing a replacement battery:
Your smoke/CO Alarm requires two AA Energizer E91 batteries. These
Actual battery service life depends on the Smoke/CO Alarm and the
environment in which it is installed.All the batteries specified above are
acceptable replacement batteries for this unit. Regardless of the manufactur-
er’s suggested battery life, you MUST replace the battery immediately once
the unit starts “chirping” (the “low battery warning”).

Regulatory information for smoke alarms
British standards (BSI) recommendations
BS 5839 part 6 (Code of practice for the design and installation of fire
detection and alarm systems in dwellings)
Smoke Alarms shall be installed in all circulation spaces (normally hallways
and staircases) that form part of escape routes, one on every level, and in
all rooms and areas that present a high fire risk.Additionally, Smoke Alarms
should also be installed between the sleeping area(s) and the most likely
sources of fire (living room and kitchen).
If there are long hallways, corridors, or protected rooms or areas over 7.5
metres (25 feet) from the nearest unit, the installation of additional Smoke
Alarms may be necessary. Roof voids containing stored combustibles or
sources of ignition may also warrant the installation of additional Smoke Alarms.
The installation of Smoke Alarms in kitchens, toilets, bathrooms or shower
rooms is not
recommended, as these locations occasionally experience
conditions that can result in improper operation.
More specifically, install smoke alarms:
• Where temperatures normally remain between 4.4˚C (40˚F) and
• On every level of your home, including finished lofts.
• Inside every bedroom, especially if people sleep with doors closed.
• In the hall near every sleeping area. If your home has multiple sleeping
areas, install a unit in each. If a hall is over 7.5 metres (25 feet) long,
install an alarm at each end.
• At the top of the first-to-second floor and subsequent floor stairways,
and at the bottom of the ground floor stairway.
Specific requirements for Smoke Alarm installation may vary from region to
region. Check with your local Fire Brigade and Building Control for current
requirements in your area.
About smoke alarms
Battery (DC) powered smoke alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed. Units
are easy to install, and do not require professional installation. May also be
interconnected, model dependent, so if one unit senses smoke, all units alarm.
Mains (AC) powered smoke alarms: Can be interconnected so if one unit
senses smoke, all units alarm.They do not operate if electricity fails. Mains (AC)
with battery (DC) back-up: will operate if electricity fails,
are fresh and correctly installed. Mains (AC) powered and mains powered with
battery back-up (AC/DC) units must be installed by a qualified electrician.
All these Smoke Alarms are designed to provide early warning of fires if
located, installed and cared for as described in the user’s manual, and if smoke
reaches them. If you are unsure which type of Smoke Alarm to install, refer to
British Standard (BS) 5839 Part 6 and 5588 Part 1. BSI, 389 Chiswick High
Road, London,W4
4AL, UK. Local building regulations may also require
specific units in new construction or in different areas of the home.
Special compliance considerations
This Smoke Alarm alone is not a suitable substitute for complete fire detection
systems in places housing many people—like blocks of flats (communal escape
routes), hotels, motels, hostels, inns, hospitals, long-term health care facilities,
nursing homes, day care facilities, boarding houses or sheltered housing of any
kind—even if they were once single-family residences.

Special compliance considerations, continued
It is not a suitable substitute for complete fire detection systems in ware-
houses, industrial facilities, commercial buildings, and special-purpose non-
residential buildings which require special fire detection and alarm systems.
Depending on the building regulations in your area, this Smoke Alarm may
be used to provide additional protection in these facilities.
The following information applies to all four building types below:
In new construction, most building regulations require the use of mains
(AC) or mains powered with integral standby supply (AC/DC) Smoke
Alarms only. In existing construction, mains powered (AC), mains powered
with integral standby supply (AC/DC), or battery (DC) powered Smoke
Alarms can be used as specified by local building regulations. Refer to
British Standard BS 5839 Part 6 and BS 5588 Part 1, local buildings regula
-
tions, or consult your Fire Brigade for detailed fire protection requirements
in buildings not defined as “dwellings.”
1. Single-family residence: Single family home. It is recommended Smoke
Alarms be installed in all circulation spaces (normally hallways and staircases)
that form part of escape routes, on every level, in all rooms and areas that
present a high fire risk and between the sleeping area(s) and the most likely
sources of fire (living room and kitchen).
2. Multi-family or mixed occupant residence: Blocks of flats.This Smoke
Alarm is suitable for use in individual flats, provided a primary fire detec-
tion system already exists to meet fire detection requirements in common
areas like foyers,
hallways, corridors, or porches. Using this Smoke Alarm in
common areas may not provide sufficient warning to all residents or meet
local fire protection by-laws/regulations.
3. Institutions: Hospitals, day care facilities, long-term health care facilities.
This Smoke Alarm may be suitable for use in individual patient sleeping/
resident rooms, provided a primary fire detection system already exists to
meet fire detection requirements in common areas like foyers, hallways,
corridors, or porches. Using this Smoke Alarm in common areas may not
provide sufficient warning to all residents or meet local fire protection
by-laws/regulations.
4. Hotels and motels:Also hostels, inns, boarding houses and sheltered
housing.This Smoke Alarm may be suitable for use inside individual sleeping/
resident rooms, provided a primary fire detection system already exists to
meet fire detection requirements in common areas like f
oyers, hallways,
corridors, or porches. Using this Smoke Alarm in common areas may not
provide sufficient warning to all residents or meet local fire protection
by-laws/regulations.
• When installing on the wall, the top edge of Smoke/CO Alarms should
be placed between 102 mm (4 inches) and 305 mm (12 inches) from
the wall/ceiling line.
• When installing on the ceiling, place the alarm as close to the center as
possible.
• In either case, install at least 102 mm (4 inches) from where the wall
and ceiling meet. See “Avoiding Dead Air Spaces” for more information.
NOTE: For any location, make sure no door or other obstruction could
keep carbon monoxide or smoke from reaching the Alarm.
Where this alarm should NOT be installed
Do NOT locate this Smoke/CO Alarm:
• In garages, kitchens, boiler rooms, crawl spaces and unfinished lofts.
Avoid extremely dusty, dirty or greasy areas.
• Where combustion particles are produced. Combustion particles form
when something burns.Areas to avoid include poorly ventilated
kitchens, garages, and boiler rooms. Keep units
at least 6 metres (20
feet) from the sources of combustion particles (cooker, boiler, water
heater, space heater) if possible. In areas where a 6-metre (20-foot)
distance is not possible – in modular, mobile, or smaller homes, for
example – it is recommended the Smoke/CO Alarm be placed as far
from these fuel-burning sources as possible.The placement recommen-
dations are intended to keep these Alarms at a reasonable distance
from a fuel-burning source, and thus reduce “unwanted” alarms.
Unwanted alarms can occur if a Smoke/CO Alarm is placed directly
next to a fuel-burning source.Ventilate these areas as much as possible.
• Within 1.5 metres (5 feet) of any cooking appliance. In air streams near
kitchens.Air currents can draw cooking smoke into the smoke sensor
and cause unwanted alarms.
• In extremely humid areas.This Alarm should be at least 3 metres (10
feet) from a shower, sauna, humidifier, va
porizer, dishwasher, laundry
room, utility room, or other source of high humidity.
• In direct sunlight.
• In turbulent air, like near ceiling fans or open windows. Blowing air may
prevent CO or smoke from reaching the sensors.
• In areas where temperature is colder than 4.4˚C (40˚F) or hotter than
37.8˚C (100˚F).These areas include non-airconditioned crawl spaces,
unfinished lofts, uninsulated or poorly insulated ceilings, porches, and
garages.
• In insect infested areas. Insects can clog the openings to the sensing
chamber.
• Less than 305 mm (12 inches) away from fluorescent lights. Electrical
“noise” can interfere with the sensor.
• In “dead air” spaces. See “Avoiding Dead Air Spaces”.
Avoiding dead air spaces
“Dead air” spaces may prevent smoke from reaching the Smoke/CO Alarm.
To avoid dead air spaces, follow installation recommendations below.
On ceilings, install Smoke/CO Alarms as close to the center
of the ceiling as
possible. If this is not possible, install the Smoke/CO Alarm at least 102 mm
(4 inches) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of Smoke/
CO Alarms should be placed between 150 mm (6 inches) and 305 mm
(12 inches) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install first Smoke/CO Alarm
within 0.9 metres (3 feet) of the peak of the ceiling, measured horizontally.
Additional Smoke/CO Alarms may be required depending on the length,
angle, etc. of the ceiling's slope. Refer to BS 5839 Part 6, 5588 Part 1 and
local building regulations for details on requirements for sloped or peaked
ceilings.
Where to install this alarm, continued
More specifically, install combination Smoke/CO Alarms:
• Where temperatures normally remain between 4.4˚C (40˚F) and
37.8˚C (100˚F).
•
On every level of your home, including finished lofts.
• Inside every bedroom, especially if people sleep with doors closed.
• In the hall near every sleeping area. If your home has multiple sleeping
areas, install a unit in each. If a hall is over 7.5 metres (25 feet) long,
install an alarm at each end.
• At the top of the first-to-second floor and subsequent floor stairways,
and at the bottom of the ground floor stairway.
This equipment should be installed in accordance with the National Fire
Protection Association’s Standard 72 (Batterymarch Park, Quincy, MA 02269).
Specific requirements for Smoke/CO Alarm installation may vary from region
to region. Check with your local Fire Brigade and Building Control for
current requirements in your area.
INSTALLATION
Where to install this alarm
Installing Smoke Alarms in Single-Family Residences
British Standards (BSI) recommend as a minimum one Smoke Alarm on
every floor of your home, and between sleeping areas and potential
sources of fire such as living rooms and kitchens. In single storey homes
with one sleeping area a Smoke Alarm should be installed in the hallway, as
close as possible to the living accommodation. See “British Standards (BSI)
Recommendations” for details. For additional coverage, it is recommended
that you also install a Smoke Alarm in bedrooms in anticipation of fires
originating there, in halls, storage areas, finished loft and roof voids. Make
sure no door or other obstruction could keep smoke from reaching the
Smoke Alarms or minimize the sound level produced from ensuring the
occupants from hearing the alarm signal.

mounting bracket. If the unit is locked to
the bracket, see the section “To Unlock
the Mounting Bracket.”
2. Insert a flathead screwdriver under the
head of the locking pin, and gently pry it
out of the battery compartment lock.
(If you plan to relock the battery compart-
ment, save the locking pin.)
3. To relock the battery compartment, close
the battery door and reinsert locking pin in
lock.
4. Reattach the Smoke/CO Alarm to the
mounting bracket.
When replacing the batteries, always test the
Smoke/CO Alarm before re-locking the battery

•
NEVER use an open flame of any kind to test this unit.You might
accidentally damage or set fire to the unit or to your home.
The built-in test switch accurately tests the unit’s operation.
• DO NOT stand close to the Alarm when the horn is sounding.
Exposure at close range may be harmful to your hearing.
When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working
properly. Using the test button is the recommended way to test this
Smoke/CO Alarm.
Push and hold the Test/Silence button 3-5 seconds until unit starts to alarm.
• The Alarm horn will sound 3 beeps, pause, 3 beeps.The
Power/Smoke LED flashes Red and the CO LED will be Off.
• Next the horn will sound 4 beeps, pause, 4 beeps.The Power/Smoke
LED will be Off and the CO LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed,
and
test again. If the unit still does not alarm, replace it immediately.
1. Mild Exposure: Slight headache, nausea, vomiting, fatigue (often described
as "Flu-like" symptoms).
2. Medium Exposure: Severe throbbing headache, drowsiness, confusion,
fast heart rate.
3. Extreme Exposure: Unconsciousness, convulsions, cardiorespiratory
failure, death.
4. Many cases of reported CARBON MONOXIDE POISONING indicate that
while victims are aware they are not well, they become so disoriented they
are unable to save themselves by either exiting the building or calling for
assistance. Young children and household pets are typically the first affected.
The Alarm may not have time to alarm before the fire itself causes damage,
injury, or death, since smoke from some fires may not reach the unit
immediately. Examples of this include children playing with matches, fires
caused by violent explosions resulting from escaping gas or fires where the
victim is in contact with burning materials such as a mattress.
Replace alarm 60 months
after installation.
Recommended Placement
Some individuals are more sensitive to CO than others, including people
with cardiac or respiratory problems, infants, unborn babies, pregnant
mothers, or elderly people can be more quickly and severely affected by
CO. Members of sensitive populations should consult their doctors for
advice on taking additional precautions.
Finding the source of CO after an alarm
Carbon monoxide is an odorless, invisible gas, which often makes it difficult
to locate the source of CO after an alarm.These are a few of the factors
that can make it difficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may be
difficult to locate the source of CO. John Lewis shall not be obligated to
pay
for any carbon monoxide investigation or service call.
