Wiring 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 electrician 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

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.

• WARNING: The alarm cannot be operated from power

derived from a square wave, modified square wave or modified

sine wave, inverter. 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.
