Specifications
The carbon monoxide alarm shall be Kidde Unit Number KN-
COP-DP-LS (part number 900-0234) or approved equal. It shall be 
powered by a 120VAC, 60 Hz source along with a 9V battery back 
up. 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.
The CO sensor shall be of a fuel cell design and shall meet 
the sensitivity requirements of Underwriters Laboratories UL2034 
Single and Multiple Station Carbon Monoxide Alarms. The unit 
shall provide accuracy of ± 30% when reading CO concentration 
levels.
The alarm shall include an integral plug that can be installed in 
any outlet following the UL/NFPA/Manufacturer’s recommended 
guidelines. The AC blades remain vertical independent of whether 
the electrical socket is mounted vertically or horizontally. The 
unit shall incorporate a digital display that meets the sensitivity 
requirements of UL 2034. The display will identify the levels of 
CO in parts per million (ppm) once that level reaches 30ppm (i.e.: 
“abnormal” levels). The display will have a red dot in the lower 
right corner that will blink to indicate the normal operation.
The alarm shall include a test/reset button. If pressed and re-
leased during normal operation, it shall electronically simulate the 
presence of CO and cause the unit to go into alarm. This sequence 
tests the unit’s electronics to ensure proper operation. If pressed 
during alarm mode, the unit will be silenced and will begin moni-
toring CO levels again.
The alarm shall include Tamper Resist Feature. If activated, unit 
shall go into constant alarm mode until the unit is replaced into 
the wall socket or the battery is removed. In accordance with UL 
2034, 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 alarm shall include a piezoelectric horn that is rated at 85 
decibels at 10 feet. When the unit detects carbon monoxide, the 
alarm pattern will be four (4) short beeps – followed by five (5) 
seconds of silence – followed by four (4) short beeps. A number 
reading will appear on the digital display identifying the measured 
CO concentration (in ppm).
