This smoke alarm uses an extremely small amount of radioactive element in the ion-
ization chamber (see Section 9). Do not try to repair the smoke alarm yourself.
Refer to the instructions in Section 12 for service.
1.RECOMMENDED LOCATIONS FOR ALARMS
• Locate the first alarm in the immediate area of the bedrooms. Try to protect the
exit path as the bedrooms are usually farthest from the exit. If more than one
sleeping area exists, locate additional alarms in each sleeping area.
• Locate additional alarms to protect any stairway as stairways act like chimneys for
smoke and heat.
• Locate at least one alarm on every floor level.
• Locate an alarm in every bedroom.
• Locate an alarm in every room where electrical appliances are operated (i.e.
portable heaters or humidifiers).
• Locate an alarm in every room where someone sleeps with the door closed.
The closed door may prevent the alarm from waking the sleeper.
• Smoke, heat, and combustion products rise to the ceiling and spread horizontally.
Mounting the smoke alarm on the ceiling in the center of the room places it closest
to all points in the room. Ceiling mounting is preferred in ordinary residential
construction.
• For mobile home installation, select locations carefully to avoid thermal barriers that
may form at the ceiling. For more details, see MOBILE HOME INSTALLATION below.
• When mounting an alarm on the ceiling, locate it at a minimum of 4” (10 cm)
from the side wall. (see Figure 1).
• When mounting the alarm on the wall, use an inside wall with the top edge of the
alarm at a minimum of 4” (10 cm) and a maximum of 12” (30.5 cm) below the
ceiling. (see Figure 1).
• Put smoke alarms at both ends of a bedroom hallway or large room if the hallway
or room is more than 30 feet (9.1 m) long.
• Install Smoke Alarms on sloped, peaked or cathedral ceilings at or within 3ft (0.9m)
of the highest point (measured horizontally). NFPA 72 states: “Smoke alarms in
rooms with ceiling slopes greater than 1 foot in 8 feet (.3m in 2.4 m) horizontally
shall be located on the high side of the room.” NFPA 72 states: “A row of detec-
tors shall be spaced and located within 3 ft (0.9m) of the peak of the ceiling meas-
ured horizontally” (see Figure 3).
MOBILE HOME INSTALLATION
Mobile homes built in the past five to seven years have been designed to be energy
efficient. Install smoke alarms as recommended above (see Figure 1).
In mobile homes that are not well insulated compared to present standards, extreme
heat or cold can be transferred from the outside to the inside through poorly insulated
walls and roof. This may create a thermal barrier which can prevent the smoke from
reaching an alarm mounted on the ceiling. In such units, install the smoke alarm on
an inside wall with the top edge of the alarm at a minimum of 4” (10 cm) and a
maximum of 12” (30.5 cm) below the ceiling (see Figure 1).
If you are not sure about the insulation in your mobile home, or if you notice that the
outer walls and ceiling are either hot or cold, install the alarm on an inside wall. For
minimum protection, install at least one alarm close to the bedrooms. For additional
protection, see SINGLE FLOOR PLAN in Figure 2.

2.LOCATIONS TO AVOID
• In the garage. Products of combustion are present when you start your
automobile.
• Less than 4” (10cm) from the peak of an “A” frame type ceiling.
• In an area where the temperature may fall below 40ºF or rise above 100ºF.
• In dusty areas. Dust particles may cause nuisance alarm or failure to alarm.
• In very humid areas. Moisture or steam can cause nuisance alarms.
• In insect-infested areas.
• Smoke alarmsshould notbe installedwithin 3ft (.9m)of thefollowing: thedoor toa
kitchen, thedoor toa bathroom containinga tubor shower, forcedair ductsused for
heating orcooling, ceilingor wholehouse ventilatingfans, orother highair flow
areas.
• Kitchens. Normal cooking may cause nuisance alarms. If a kitchen alarm is desired,
it should have an alarm silence feature or be a photoelectric type.
• Near fluorescent lights. Electronic “noise” may cause nuisance alarms.
3.INSTALLATION INSTRUCTIONS

1. To insure aesthetic alignment of the
alarm with the hallway or wall, the
“A” line on the mounting bracket
must be parallel with the hallway
when ceiling mounting or horizon-
tal when wall mounting.
2. After selecting the proper smoke alarm location as described in Section 1, attach
the mounting bracket to the ceiling as shown in Figure 3. For wall mounting see
Figure 4. Place the mounting plate on the wall; be sure the “A” line is horizontal
(parallel to the floor). Use the screws and anchors provided to secure the mounting
bracket (use 3/16” drill bit for anchors).
3. This alarm has batteries permanently sealed inside the alarm no battery installation
is necessary.
ACTIVATING THE ALARM
This model is equipped with a feature that automatically activates the alarm
when the alarm is mounted to the mounting bracket for the first time. Once
activated, the batteries will supply power to the alarm for the life of the
alarm (10 years). Be sure that the mounting bracket is mounted correctly
before installing the alarm on the mounting bracket.
1. To activate the alarm, install the alarm on the mounting bracket (Figure 6) and
rotate the alarm clockwise (as indicated on the alarm cover) until the alarm ratchets
into place (the ratcheting function allows for aesthetic alignment). NOTE: The
alarm will mount to the bracket in four (4) positions (every 90 degrees).
The alarm is now activated!
2. After installation/activation, test your alarm by depressing and holding down the
test button for a minimum of 5 seconds (or until the alarm sounds). This should
sound the alarm. CAUTION: Due to the loudness (85 decibels) of the alarm,
always stand an arms length away from the unit when testing.
TAMPER RESIST FEATURE
Smoke Alarm Tamper Resist Feature
This alarm is equipped with a tamper resist feature that prevents someone from
removing the unit from the mounting bracket. When activated, it can be very effec-
tive in preventing smoke alarm removal or tampering.
Activate the smoke alarm tamper resist feature by breaking off the four posts in the
square holes in the mounting bracket (see Figure 7). When the posts are broken off,
the tamper resist on the base is allowed to engage the mounting bracket. Rotate the
alarm onto the mounting bracket until you hear the tamper resist tab snap into place,
locking the alarm on the mounting bracket. Using the tamper resist feature will deter
children and others from removing the alarm from the bracket. NOTE: To remove the
alarm when the tamper resist tab is engaged, press down on the tamper resist tab
and rotate the alarm in the direction indicated by the arrows on the cover of the
alarm (see Figure 8).

4.OPERATION AND TESTING
OPERATION: The smoke alarm is operating once the alarm is activated (see Section 3)
and testing is complete. When products of combustion are sensed, the unit sounds a
loud 85db pulsating alarm until the air is cleared.
SMART HUSH
TM
CONTROL: The SMART HUSH
TM
feature has the capability of temporar-
ily desensitizing the alarm circuit for approximately 8 minutes. This feature is to be
used only when a known alarm condition, such as smoke from cooking, activates the
alarm. The smoke alarm is desensitized by pushing the HUSH
®
button on the smoke
alarm cover. If the smoke is not too dense, the alarm will silence immediately and the
red LED will illuminate for 1.5 seconds every 8 seconds for 8 minutes. This indicates
that the alarm is in a temporarily desensitized condition. The smoke alarm will auto-
matically reset after approximately 8 minutes and sound the alarm if particles of com-
bustion are still present. The SMART HUSH
TM
feature can be used repeatedly until the
air has been cleared of the condition causing the alarm. Pushing the test/reset button
on the alarm will end the temporarily desensitized period.
NOTE: DENSE SMOKE WILL OVERRIDE THE SMART HUSH
TM
CONTROL FEATURE
AND SOUND A CONTINUOUS ALARM.
CAUTION: BEFORE USING THE ALARM SMART HUSH
TM
FEATURE, IDENTIFY THE
SOURCE OF THE SMOKE AND BE CERTAIN A SAFE CONDITION EXISTS.
FLASHING LED LIGHT: This smoke alarm is equipped with a flashing red indicator light
with four modes of operation:
• The LED will flash every 40-45 seconds in the standby mode signifying that the
alarm is receiving power.
• The LED will flash every 1.5 seconds when the alarm is sounding.
• The LED will illuminate for 1.5 seconds every 8 seconds while the alarm is in the
temporarily desensitized mode.
• If alarm memory has been set (see below for alarm memory description), the LED
will flash rapidly when the test button is pressed.
ALARM MEMORY: This smoke alarm has an memory function that will inform you if
the alarm has sounded since the test button was last pressed. The alarm memory will
cause the red LED to flash rapidly when the test button is pressed. The alarm memory
is reset when the test button is released.
TESTING: Test by pushing the test button on the cover and holding it down for a
minimum of 5 seconds (or until the alarm sounds). This will sound the alarm if the
electronic circuitry, horn, and batteries are working. If no alarm sounds, the unit has
defective batteries or other failure. DO NOT use an open flame to test your alarm, you
could damage the alarm or ignite combustible materials and start a structure fire.
NOTE: WEEKLY TESTING IS REQUIRED.
TEST THE ALARM WEEKLY TO ENSURE PROPER OPERATION. Erratic or low sound com-
ing from your alarm may indicate a defective alarm, and it should be returned for
service (see Section 11).
5.NUISANCE ALARMS
Smoke alarms are designed to minimize nuisance alarms. Cigarette smoke will not
normally set off the alarm, unless the smoke is blown directly into the alarm.
Combustion particles from cooking may set off the alarm if the alarm is located close
to the cooking area. Large quantities of combustible particles are generated from
spills or when broiling. Using the fan on a range hood which vents to the outside
(non-recirculating type) will also help remove these combustible products from the
kitchen.
This model 0910 has a SMART HUSH
TM
control that is extremely useful in a kitchen
area or other areas prone to nuisance alarms. For more information refer to Section 4,
OPERATION AND TESTING.
If the alarm does sound, check for fires first. If a fire is discovered, get out and call
the fire department. If no fire is present, check to see if one of the reasons listed in
Section 2 may have caused the alarm.
6.MAINTENANCE
BATTERY ACTIVATION AND DEACTIVATION
NOTE: Three Lithium-Ion batteries, permanently sealed inside the alarm, power this
unit; no battery installation or replacement is necessary for the life of the alarm.
WARNING! DO NOT ATTEMPT TO OPEN THE ALARM FOR ANY REASON!
To activate the alarm, attach the alarm to the mounting bracket by rotating in the
direction of the arrows on the cover, see ACTIVATING ALARM in Section 3 (INSTALLA-
TION INSTRUCTIONS).
This alarm has a low battery monitor circuit which will cause the alarm to “chirp”
approximately every 40-45 seconds, for a minimum of thirty (30) days, at the end of
the life of the alarm to indicate that the alarm needs replacement. To deactivate the
alarm remove the alarm from the mounting bracket by rotating the alarm in the direc-
tion indicated by the arrows on the cover of the alarm and locate the crosshatched
area on product label. NOTE: If the tamper resist feature has been activated, see
TAMPER RESIST FEATURE in Section 3 (INSTALLATION INSTRUCTIONS).
WARNING! DO NOT DEACTIVATE THE ALARM UNTIL THE END OF THE ALARM
LIFE, WHEN A “CHIRP” IS HEARD EVERY 40-45 SECONDS. ONCE THE ALARM IS
DEACTIVATED THE BATTERIES WILL BE DEPLEATED AND THE ALARM WILL NO
LONGER FUNCTION.
WARNING! ONCE THE ALARM HAS BEEN DEACTIVATED, IT CANNOT BE
REACTIVATED!
WARNING! ONCE THE ALARM HAS BEEN DEACTIVATED, IT CANNOT BE
MOUNTED ONTO THE MOUNTING BRACKET!
Break out the crosshatched area with a screwdriver or similar tool. Using a screwdriv-
er or similar tool slide the exposed piece towards the center of the alarm. This will
deactivate the alarm, stop the low battery “chirp” and render the alarm safe for
disposal by draining the batteries.
CLEANING YOUR ALARM
YOUR ALARM SHOULD BE CLEANED AT LEAST ONCE A YEAR
If the tamper resist feature has been activated you will need to follow the instructions
in Section 3 to remove your alarm for maintenance.
To clean your alarm, remove it from the mounting bracket as outlined in the begin-
ning of this section. You can clean the interior of your alarm (sensing chamber) by
using compressed air or a vacuum cleaner hose and blowing or vacuuming through
the openings around the perimeter of the alarm. The outside of the alarm can be
wiped with a damp cloth.
After cleaning, reinstall your alarm and test your alarm by using the test button. If
cleaning does not restore the alarm to normal operation the alarm should be replaced.
7.LIMITATIONS OF SMOKE ALARMS
WARNING: PLEASE READ CAREFULLY AND THOROUGHLY
• NFPA 72 states: Life safety from fire in residential occupancies is based primarily on
early notification to occupants of the need to escape, followed by the appropriate
egress actions by those occupants. Fire warning systems for dwelling units are
capable of protecting about half of the occupants in potentially fatal fires. Victims
are often intimate with the fire, too old or young, or physically or mentally impaired
such that they cannot escape even when warned early enough that escape should
be possible. For these people, other strategies such as protection-in-place or assist-
ed escape or rescue are necessary.
• Smoke alarms are devices that can provide early warning of possible fires at a rea-
sonable cost; however, alarms have sensing limitations. Ionization type alarms offer
a broad range of fire sensing capabilities but are better at detecting fast flaming
fires than slow smoldering fires. Photoelectric alarms sense smoldering fires better
than flaming fires. Home fires develop in different ways and are often unpre-
dictable. Neither type of alarm (photoelectric or ionization) is always best, and a
given alarm may not always provide warning of a fire.
• Abatterypoweredalarmmusthaveabatteryofthespecifiedtype,ingoodcondition
andinstalledproperly.
• A.C. powered alarms (without battery backup) will not operate if the A.C. power
has been cut off, such as by an electrical fire or an open fuse.
• Smoke alarms must be tested regularly to make sure the batteries and the alarm
circuits are in good operating condition.
• Smoke alarms cannot provide an alarm if smoke does not reach the alarm.
Therefore, smoke alarms may not sense fires starting in chimneys, walls, on roofs,
on the other side of a closed door or on a different floor.
• If the alarm is located outside the bedroom or on a different floor, it may not wake
up a sound sleeper.
• The use of alcohol or drugs may also impair one’s ability to hear the smoke alarm.
For maximum protection, a smoke alarm should be installed in each sleeping area
on every level of a home.
• Although smoke alarms can help save lives by providing an early warning of a fire,
they are not a substitute for an insurance policy. Home owners and renters should
have adequate insurance to protect their lives and property.
8. GOOD SAFETY HABITS
DEVELOP AND PRACTICE A PLAN OF ESCAPE
• Install and maintain Fire extinguishers on every level of the home and in the
kitchen, basement and garage. Know how to use a fire extinguisher prior to an
emergency.
• Make a floor plan indicating all doors and windows and at least two (2) escape
routes from each room. Second story windows may need a rope or chain ladder.
• Have a family meeting and discuss your escape plan, showing everyone what to do
in case of fire.
• Determine a place outside your home where you all can meet if a fire occurs.
• Familiarize everyone with the sound of the smoke alarm and train them to leave
your home when they hear it.
• Practice a fire drill at least every six months, including fire drills at night. Ensure
that small children hear the alarm and wake when it sounds. They must wake up in
order to execute the escape plan. Practice allows all occupants to test your plan
before an emergency. You may not be able to reach your children. It is important
they know what to do.
WHAT TO DO WHEN THE ALARM SOUNDS
• Alert small children in the home.
• Leave immediately by your escape plan. Every second counts, so don’t waste time get-
ting dressed or picking up valuables.
• In leaving, don’t open any inside door without first feeling its surface. If hot, or if you
see smoke seeping through cracks, don’t open that door! Instead, use your alternate
exit. If the inside of the door is cool, place your shoulder against it, open it slightly and
be ready to slam it shut if heat and smoke rush in.
• Stay close to the floor if the air is smoky. Breathe shallowly through a cloth, wet if
possible.
• Once outside, go to your selected meeting place and make sure everyone is there.
• Call the fire department from your neighbor’s home - not from yours!
• Don’t return to your home until the fire officials say that it is all right to do so.
There are situations where a smoke alarm may not be effective to protect against fire as
stated in the NFPA Standard 72. For instance:
a) smoking in bed
b) leaving children home alone
c) cleaning with flammable liquids, such as gasoline
9. NRC INFORMATION
Ionization type smoke alarms use a very small amount of a radioactive element in the
sensing chamber to enable detection of visible and invisible combustion products.
The radioactive element is safely contained in the chamber and requires no adjust-
ments or maintenance. This smoke alarm meets or exceeds all government standards.
It is manufactured and distributed under license from the U.S. Nuclear Regulatory
Commission.
10. NFPA REQUIRED PROTECTION
The National Fire Protection Association’s Standard 72 provides the following informa-
tion:
Smoke alarms shall be installed outside each separate sleeping area in the immediate
vicinity of the bedrooms and on each additional story of the family living unit, includ-
ing basements and excluding crawl spaces and unfinished attics. In new construction,
a smoke alarm also shall be installed in each sleeping room.
Smoke Detection - Are More Smoke Alarms Desirable? The required number of
smoke alarms might not provide reliable early warning protection for those areas sep-
arated by a door from the areas protected by the required smoke alarms. For this rea-
son, it is recommended that the householder consider the use of additional smoke
alarms for those areas for increased protection. The additional areas include the base-
ment, bedrooms, dining room, furnace room, utility room, and hallways not protected
by the required smoke alarms. The installation of the smoke alarms in the kitchen,
attic (finished or unfinished), or garage is normally not recommended, as these loca-
tions occasionally experience conditions that can result in improper operation.
This equipment should be installed in accordance with the National Fire Protection
Association’s Standard 72 (NFPA, Batterymarch Park, Quincy, MA 02269).
NOTIFY YOUR LOCAL FIRE DEPARTMENT AND INSURANCE COMPANY OF YOUR
SMOKE ALARM INSTALLATION.
11. CAUTION (AS REQUIRED BY THE
CALIFORNIA STATE FIRE MARSHAL)
“Early warning fire detectionis bestachieved bythe installationof fire detectionequip-
ment inall rooms andareasof thehousehold asfollows. Asmoke alarminstalled in
each separatesleeping area (inthe vicinityof, butoutside ofthe bedrooms), andheat or
smoke detectorsin theliving rooms, diningrooms,bedrooms, kitchens,hallways, attics,
furnace rooms,closets, utilityand storagerooms,basements andattached garages.”
The NFPA suggests that alarms installed within 20' (6.1m) of cooking appliances shall
have an alarm silence feature or be of the photoelectric type.
