Wiring Requirements
• This alarm should be installed on a UL 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 maximum wire run distance between the first and last unit in an interconnected system is
1000 feet.
• The appropriate power source is 120 Volt AC Single Phase supplied from a non-switchable circuit.
• Smoke alarms are not to be used with detector guards unless the combination (alarm and detector
guard) has been evaluated and found suitable for that purpose.
• Kidde alarms are not designed, agency tested or certified for recessed mounting and should not
be installed in this manner. Recessed mounting impedes smoke entry into the smoke chamber,
which may prevent the alarm from sounding in a timely manner. This could endanger the lives of
occupants in the residence. Kidde alarms are designed, tested and certified for wall (if applicable)
and ceiling surface mount only.
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.

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 hardwire interconnected, all interconnected units must be powered from a single
circuit.
