Wiring
Wiring Requirements:
•This Smoke/CO Alarm should be installed on a CSA
listed or recognized junction box. All connections
should be made by a qualified electrician and must
conform to codes having jurisdiction in your area.
•The appropriate power source is 120 V AC Single
Phase supplied from a non-switchable circuit, which
is not protected by a ground fault interrupter.
•The alarm should not be operated on power derived
from a square wave or modified square wave
inverter. These power sources produce high peak
voltages that will damage the alarm.
• Smoke alarms are not to be used with detector
guards unless the combination (alarm and guard) has
been evaluated and found suitable for that purpose.
Wiring 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 any t h i n g. 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 products may be
interconnected in a multiple station arrangement:
Limit of 12 smoke alarms and/or 18 alarms total
(smoke, CO, Smoke/CO Combination, heat, etc.).
This Smoke/CO Combination alarm is counted as a
smoke alarm when determining the maximum
number of units on an interconnect line. With 18
alarms interconnected, it is still possible to
interconnect up to a total of 6 remote signaling

1312
devices and/or relay modules (see Page 16 for
details on interconnecting Kidde devices).
•The maximum wire run distance between the first
and last unit in an interconnected system is 305 m
(1000’).
•Figure 1 illustrates interconnection wiring. Improper
connection will result in damage to the alarm, failure
to operate, or a shock hazard.
•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.
