Wires on the A.C.Quick-Connector Alarm Harness:
Black Connected to hot side of A.C. line.
White Connected to neutral side of A.C. line.
Red Connected to interconnect lines (red wires)
of other units in a multiple-station set-up.
Interconnecting
This CO Alarm is interconnectable with other multiple-
station Kidde products (refer to list on page 3). It is not
designed to be interconnected with any other
manufacturer’s products.
• When compatible Kidde smoke alarms and heat alarms
are interconnected to your CO alarm, they will only
respond to a smoke or heat related event.
• When mixing Kidde alarms which have battery back-up
with models without battery back-up, be advised that
the models without battery back-up will not function
during an A.C. power failure.
• For alarms that are being used as single station alarms,
do not connect the red wire to anything. Leave the red
wire insulating cap in place to make certain that the red
wire cannot contact any metal parts or the electrical box.
• All interconnectable alarms should be installed on a CSA
Listed or recognized junction box. All connections
should be made by a qualified electrician and must
conform to article 760 of the US National Electrical
Code, NFPA 72 and/or Canadian Electrical Code having
jurisdiction in your area.
• The appropriate power source is 120 Volt AC Single-
Phase supplied from a non-switchable circuit, which is
not protected by a ground fault interrupter.
• When alarms are interconnected, all interconnected units
must be powered from a single circuit.
• A maximum of 24 Kidde devices may be interconnected
in a multiple-station arrangement. The interconnect
system should not exceed the NFPA interconnect limit of
12 smoke alarms and/or 18 alarms total (smoke, CO,
smoke/CO combination, heat, etc.)
Locations To Avoid
To avoid causing damage to the unit, to provide optimum
performance, and to prevent unnecessary nuisance alarms:
• Do not install in kitchens, garages or furnace rooms that
may expose the sensor to substances that could damage
or contaminate it.
• Do not install in areas where the temperature is colder
than 4.4°C (40°F) or hotter than 37.8°C (100°F) such as
crawl spaces, attics, porches and garages.
• Do not install within 5’ of heating or cooking
appliances. (Kidde recommends 15 feet to prevent
nuisance alarms)
• Do not install near vents, flues, chimneys or any
forced/unforced air ventilation openings.
• Do not install near ceiling fans, doors, windows or areas
directly exposed to the weather.
• Do not install in dead air spaces, such as peaks of
vaulted ceilings or gabled roofs, where carbon
monoxide may not reach the sensor in time to provide
early warning.
• Do not install on a switched or dimmer-controlled
outlet.
• Do not install this unit near deep cell large batteries.
Large batteries have emissions that can cause the alarm
to perform at less than optimum performance.
• Do not obstruct the vents located on the alarm. Do not
place the alarm where drapes, furniture or other objects
block the flow of air to the vents.
This Kidde CO alarm can be used independently or inter-
connected with other Kidde alarms. The alarms should be
mounted in or near bedrooms and living areas. It is
recommended that you install a Kidde CO alarm on each
level of your home.
When choosing your installation locations, make sure you
can hear the alarm from all sleeping areas. If you install
only one carbon monoxide alarm in your home, install the
alarm near bedrooms, not in the basement or furnace room.
Recommended Installation Locations
CAUTION: This alarm will only indicate the presence of carbon
monoxide at the sensor. Carbon monoxide may be present in
other areas.
WARNING: This product is intended for use in ordinary indoor
residentual areas. It is not designed to measure compliance with
commercial and industrial standards.
This device is designed to protect individuals from acute effects
of carbon monoxide exposure. It will not fully safeguard
individuals with specific medical conditions. If in doubt, consult
a medical practitioner. Individuals with medical problems may
consider using warning devices, which provide audible and visual
signals for carbon monoxide concentrations under 30 ppm. This
alarm has not been investigated for carbon monoxide detection
below 70 ppm.
IMPORTANT: Improper location can affect the sensitive
electronic components in this alarm. The installation of this
device should not be used as a substitute for proper installation,
use and maintanence of fuel-burning appliances, including
appropriate ventilation and exhaust systems. Please see the next
section describing locations to avoid.

Installation Installation
With 18 alarms interconnected, it is still possible to
interconnect up to a total of 6 remote signaling devices
and/or relay modules.
• The maximum wire run distance between the first and
last unit in an interconnected system is 305 m (1000’).
• Make certain alarms are wired to a continuous, (non-
switched) power line. NOTE: Use standard CSA Listed
household wire (18 gauge or larger as required by local
codes) available at all electrical supply stores and most
hardware stores.
Wiring
Figure 1 illustrates interconnection wiring. Improper
connection will result in damage to the alarm, failure to
operate, or a shock hazard.
CAUTION! Turn off the main power to the circuit before
wiring the alarm.
