combination (alarm and guard) has been evaluated and found
suitable for that purpose.
3. INSTALLATION INSTRUCTIONS
WIRING REQUIREMENTS
• This smoke alarm should be installed on a U.L. listed or recognized
junction box. All connections should be made by a qualified elec-
trician and all wiring used shall be in accordance with articles 210
and 300.3(B) of the U.S. National Electrical Code ANSI/NFPA 70,
NFPA 72 and/or any other 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 Volt AC Single Phase sup-
plied from a non-switchable circuit which is not protected by a
ground fault interrupter.
• WARNING: This alarm cannot be operated from power derived
from a square wave, modified square wave or modified sine wave
inverters. These types of inverters are sometimes used to supply
power to the structure in off grid installations, such as solar or
wind derived power sources. 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 devices may be interconnected in a mul-
tiple station arrangement. The interconnect system should not
exceed the NFPA interconnect limit of 12 smoke alarms and/or 18
alarms total (smoke, heat, carbon monoxide, etc.). With 18 alarms
interconnected, it is still possible to interconnect up to a total of 6
remote signaling devices and/or relay modules.
