Wiring Requirements - Kidde KN-COSM-ICA User Manual

Installation
Wiring

Wiring Requirements:

• This smoke alarm should be installed on a CSA listed or
recognized junction box. All connections should be
made by a qualified electrician and all wiring used shall
be in accordance with codes having jurisdiction in your
area. The multiple station interconnect wiring to the
alarms must be run in the same raceway or cable as the
AC power wiring. In addition, the resistance of the
interconnect wiring shall be a maximum of 10 ohms.
• 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.
WARNING: The alarm should not be operated on power
derived from a square wave, modified square wave or
modified sine 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 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 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 devices and/or relay modules (see Page 16 for
details on interconnecting Kidde devices).
