powered by a 120VAC, 60Hz source. The unit shall incorporate an ionization 
sensor with nominal sensitivity of 0.64%/ft. The temperature operation 
range shall be between 40˚F (4˚C) to 100˚F (38˚C) and the humidity operating 
range shall be 5% - 95% relative humidity.
The smoke alarm can be installed on any standard single gang electrical 
box, up to a 4” octagon junction box. The electrical connection (to the 
alarm) shall be made with a plug-in connector. A maximum of 24 Kidde 
devices can be interconnected in a multiple station arrangement. The interconnect system must not exceed the NFPA (National Fire Protection 
Association) limit of 18 initiating devices, of which 12 can be smoke alarms. 
With 18 initiating devices (Smoke, heat, CO, etc.), interconnected, it is still 
possible to interconnect 6 strobe lights and or relay modules. The alarm 
shall provide optional tamper resistance that deters removal of the unit from 
the wall or ceiling. 
The alarm shall include a piezoelectric horn that is rated at 85 decibels 
at 10 feet. The unit shall incorporate 2 LED’s. A green LED will be constantly “ON” when AC power is present and will flash until reset (alarm memory) 
to indicate which alarm was the originating alarm at the last incident. 
Pressing the test button will reset the alarm memory condition. A red LED 
will flash once every 30-40 seconds to indicate the alarm is operating properly and will flash once per every 1.5 seconds when the unit is alarming and 
will remain so until the air is cleared.

Installation of Smoke Alarm
The smoke alarm should be installed to comply with all local codes having jurisdiction in your area, Article 760 of the National Electric Code, and NFPA 72. Make 
certain all alarms are wired to a single, continuous (non-switched) power line, 
which is not protected by a ground fault interrupter. A maximum of 1000 ft. of 
wire can be used in the interconnect system. Use standard UL listed household 
wire (18 gauge or larger as required by local codes).
