Architectural and Engineering 
Specifications
The combination smoke and carbon monoxide alarm shall be Kidde 
Model Number KN-COSMXTR-BA (part number 900-0216A) or 
approved equal. It shall be powered by 2 AA batteries. The unit 
shall incorporate an ionization smoke sensor with nominal sensitivity 
of 0.97 %/ft. The CO sensor shall be of a fuel cell design and shall 
meet the sensitivity requirements of Underwriter’s Laboratory’s UL 
2034 single and multiple station carbon monoxide alarms. The tem
-
perature 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 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 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.
