AC Wire-in Combination
Carbon Monoxide & Smoke Alarm
Part Number 900-0114A
Model KN-COSM-IBA
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).
Architectural and Engineering
Specifications
The combination smoke and carbon monoxide alarm shall be Kidde model
KN-COSM-IBA or approved equal. It shall be powered by 120VAC, 60Hz source
with two AA 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
0.89%/ft. The CO sensor shall be of a fuel cell design and shall meet the sensitiv-
ity 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 following
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 a 2 LED display. A green LED will be steady on when AC
power is present, flash every 60 seconds when in 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 alarm 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.
