Architectural and Engineering 
Specifications
The smoke alarm shall be Kidde model i12020A or approved equal.It shall 
be powered by a 120VAC, 60Hz source. The unit shall incorporate an ion-
ization sensor with nominal sensitivity of 0.50 to 1.02%/ft. The temperature 
operation range shall be between 40˚F (4˚C) to 100˚F (38˚C) and the humid-
ity 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 include Hush
TM
 feature that silences the unit for approxi-
mately 7 minutes if a nuisance condition occurs. The unit shall incorporate 
red and green LED indicators. The green LED (when illuminated) indicates the 
presence of AC power. The red LED (located under the TEST/Hush button) 
has four modes of operation:
Standby Condition: The red LED will flash every 40 seconds to indicate 
that the smoke alarm is operating properly. Alarm Condition: When the 
alarm senses products of combustion and goes into alarm the red LED will 
flash one flash per second. The flashing LED and pulsating alarm will con-
tinue until the air is cleared.When units are interconnected, only the red LED 
of the alarm that senses the smoke or is being tested (the originating unit) 
will flash.  All other units in the interconnected system will sound an alarm 
but their red LED’s will NOT flash. Alarm Memory: This smoke alarm is 
equipped with an alarm memory, which provides a visual indication when  
an alarm has been activated. The red LED will illuminate for about 1.5  
seconds every 20 seconds to indicate the memory condition.  
Hush
TM
 Mode:  The red LED will illuminate for 1.5 seconds every 10  
seconds, indicating the smoke alarm is in the Hush
TM
 Mode. 
The unit shall at a minimum meet the requirements of UL217, NFPA72, 
The State of California Fire Marshall, NFPA101 (One and two family dwell-
ings), Federal Housing Authority (FHA, Housing and Urban Development 
(HUD).

Installation of Smoke Alarm
The smoke alarm must be installed to comply with all local codes having jurisdic-
tion in your area. All wiring shall be in accordance with articles 210 and 300.3(B) 
of the US National Electrical Code, ANSI / NFPA 70 and NFPA 72. The multiple 
station interconnect wiring must be in the same raceway as the AC power wiring. 
In addition the resistance if the interconnect wiring shall be a maximum of 10 
ohms. 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.
