Specifications
The combination smoke and carbon monoxide alarm shall be Kidde
Model Number KN-COSM-BA (part number 900-0102A) or approved
equal. It shall be powered by 2 AA batteries. The unit shall incorpo-
rate an ionization smoke sensor with nominal sensitivity of 0.97 %/
ft. The CO sensor shall be of a fuel cell design and provide accuracy
of +/-20% + 15ppm. 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 combination alarm can be installed on the surface of any wall or
ceiling following the UL/NFPA/Manufacturer’s recommended place-
ment guidelines. The alarm shall provide optional tamper resistance
that deters removal of the unit from the wall or ceiling.
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 correspond-
ing 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 piezoelectric 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 also indicate a low battery warning utilizing each of the
following methods: a brief alarm chirp, the voice announcement of
“Low Battery!” and the red LED will flash once per minute. The unit
shall incorporate 2 LED’s. A green LED will flash every 60 seconds in
standby condition. A red LED will flash during smoke or CO alarm,
and in error mode.
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 7-year manufacturer’s limited warranty.
