The smoke alarm shall be Kidde Model i12010S or approved 
equal. It shall be powered by a 120VAC, 60Hz source along with 
a 3V sealed lithium battery backup. The unit shall incorporate 
an ionization sensor with nominal sensitivity of 0.50 to 1.04%/
ft. The temperature operating range shall be between 40°and 
100°F (4°C and 38°C) and the humidity operating range shall be 
up 95% relative humidity, non-condensing.
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 connec-
tor. 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. No additional pieces 
shall be required to activate this feature.
The alarm shall include a test button that will electronically simu-
late the presence of smoke and cause the unit to go into alarm. 
This sequence tests the unit’s electronics, battery and horn to 
ensure proper operation. 
The unit shall include a piezoelectric horn that is rated at 85 
decibels at 10 feet. The unit shall include the Smart Hush™ 
feature that silences the unit for approximately 9 minutes if a 
nuisance condition occurs.
The unit shall indicate a low battery condition with a brief alarm 
chirp and red LED flash once every 60 seconds. In standby con-
dition, the green LED will be constantly on when powered by 
AC, and flash every 60 seconds when powered by only battery 
backup. The green LED will also flash every 2 seconds when in 
Hush mode, and every 16 seconds in Memory Condition. 
The smoke alarm shall include an End of Life Alert, where ten 
years after initial power-up the unit shall chirp two times every 
30 seconds to indicate the alarm needs to be replaced. The End 
of Life signal can be silenced three days at a time for a maxi-
mum of 30 days. The unit shall have a deactivation switch to 
disable it and make it safe for disposal. 
The unit shall at a minimum meet the requirements of UL217, 
NFPA72, and (chapter 11), The State of California Fire Marshall, 
NFPA101 (0ne and two family dwellings), Federal Housing 
Authority (FHA), Housing and Urban Development (HUD). It shall 
also include a 10-year manufacturer’s limited warranty.

Installation of Smoke Alarm
The smoke alarm should be installed to comply with all local codes having jurisdic-
tion 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 as required 
by code.
