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 mul-
tiple 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 pro-
tected by a ground fault interrupter.

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.
