“INTERCONNECT WIRING DIAGRAM”
FIGURE 1
Install at least one (1) foot away from fluorescent lights,
electronic noise may cause nuisance alarms. Do not
place in direct sunlight and keep out of insect infested
areas. Extreme temperatures will effect the sensitivity
of the Smoke/CO Alarm. Do not install in areas where
the temperature is colder than 40 degrees Fahrenheit
(4.4 Celsius) or hotter than 100 degrees Fahrenheit
(37.8 Celsius). Do not install in areas where the relative
humidity (RH) is above 85%. Place away from doors and
windows that open to the outside.

Wiring Instructions:
WIRING REQUIREMENTS
• This Smoke/CO Alarm should be installed on a UL
Listed or recognized junction box. All connections
should be made by a qualified electrician and must
conform to article 760 of the U.S. National Electrical
Code, NFPA 72 and/or any other codes having juris-
diction 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.
• Smoke alarms are not to be used with detector
guards unless the combination (alarm and detector
guard) have been evaluated and found suitable for
that purpose.
• The alarm should not be operated on power derived
from a square wave, or modified square wave, invert-
er. These power sources produce high peak voltages
that will damage the alarm.

WIRING INSTRUCTIONS FOR AC QUICK
CONNECT HARNESS
CAUTION! TURN OFF THE MAIN POWER TO THE
CIRCUIT BEFORE WIRING THE ALARM.
• For alarms that are used as single station, 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.
• When alarms are interconnected, all interconnected
units must be powered from a single circuit.
• A maximum of 24 Kidde Safety devices may be inter-
connected 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.) This Smoke/CO combination alarm must
be counted as a smoke alarm when determining the
number of units on an interconnect line.With 18
alarms interconnected, it is still possible to intercon-
nect up to a total of 6 remote signaling devices and
/or relay modules. (See Page 16 for details on inter-
connecting Kidde devices).
