Architectural and Engineering
Specifications
The combination smoke and carbon monoxide alarm shall be
Kidde Model Number KN-COSM-B-RF (Part number 900-0225) or
approved equal. It shall be powered by three (3) AA batteries. The
unit shall incorporate an ionization sensor with nominal sensitivity
of 0.89%/ft +/- 0.19%ft. The CO sensor shall be of a fuel cell
design and provide accuracy of +/- 20% + 15ppm. The tempera-
ture operating range shall be between 40°F and 100°F (4°C and
38°C) and the humidity operating range shall be 10% to 85%
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
placement guidelines. 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 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 smoke alarm takes precedence when both
smoke and CO are present.
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 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 two LEDs. 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 UL2034, UL217,
NFPA72, (chapter 11 2002 edition) The State of California Fire Marshal,
NFPA 101 (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.
