Worry-Free 120V AC Wire-in  
Combination Smoke & Carbon Monoxide Alarm 
Sealed Lithium Battery Backup
Model i12010SCO
Architectural and Engineering
Specifications
The combination smoke and carbon monoxide alarm shall be Kidde model 
i12010SCO or approved equal. It shall be powered by 120VAC, 60Hz source with 
on 3V sealed lithium battery backup. The temperature operating range shall be 
between 40˚F and 100˚F (4˚C and 38˚C) and the humidity operating range shall be 
10% - 95% relative humidity, non-condensing.
The unit shall incorporate an ionization smoke sensor with nominal sensitivity of 
0.50-1.22%/ft. The CO sensor shall be of a fuel cell design and shall meet the sensi-
tivity requirements of Underwriters Laboratories UL2034 Single and Multiple Station 
Carbon Monoxide Detectors.
The combination alarm can be installed on the surface of any wall or ceiling follow-
ing the UL/NFPA/Manufacturer’s recommended placement guidelines. The 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. The unit 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.
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 include a test button that will electronically simulate the presence of 
smoke and CO and cause the unit to go into both modes of alarm. This sequence 
tests the unit’s electronics to ensure proper operation.
The CO sensor will not alarm to levels of CO below 30 ppm and will alarm in the 
following time range when exposed to the corresponding levels of CO.
   70 ppm CO Concentration 60 – 240 minutes 
  150 ppm CO Concentration 10 – 50 minutes 
  400 ppm CO Concentration 4 – 15 minutes
The combination alarm shall have two methods of warning for danger: a piezoelec-
tric horn that is rated at 85 decibels at 10 feet and a voice warning that identifies 
the danger. For a CO incident, the horn will sound in the repetitive manner – four 
(4) fast beeps, a short pause, four (4) fast beeps, a short pause. In between, the unit 
will announce “Warning Carbon Monoxide!” In a Smoke incident, the horn will 
sound in the repetitive manner – three (3) beeps, a pause, three (3) beeps, a pause. 
In between, the unit will announce “Fire!”
The unit shall incorporate 2 LED’s. A green LED will be steady on when AC power 
is present, flash every 60 seconds when in the battery only mode, every second to 
indicate alarm memory, and every 2 seconds to indicate the Hush“ mode is active. 
A red LED will flash in unison with the sounder pattern.
The unit shall include the Hush
TM
 feature that silences the unit for approximately 9 
minutes if a nuisance alarm condition occurs. The Green LED on the alarm will flash 
every 2 seconds while in Hush
TM
 and will automatically reset itself. It also provides 
voice annunciation of “Hush Mode Activated” when Hush
TM
 is activated and “Hush 
Mode Cancelled” when the Hush cycle ends.
The unit shall also indicate a low battery warning utilizing each of the following 
methods: a brief alarm chirp, the voice announcement of “Low Battery!” 
The unit shall at a minimum meet the requirements of UL 2034, UL217, NFPA72, 
(chapter 11 2002 edition) The State of California Fire Marshall, NFPA101 (One 
and two family dwellings) Federal Housing Authority (FHA), Housing and Urban 
Development (HUD). It shall also include a 10-year manufacturer’s limited warranty.
Ordering Information
Installation of Smoke Alarm
The combination 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 intercon-
nect system. Use standard UL listed household wire (18 gauge or larger  
as required by local codes).
