CO ALARM SPECIFICATIONS 
 
Gas Detection at Typical Temperature and 
Humidity Ranges: 
 
The CO Alarm is not 
formulated to detect CO levels below 30 ppm 
typically. UL tested for false alarm resistance to 
Methane (500 ppm), Butane (300 ppm), 
Heptane (500 ppm), Ethyl Acetate (200 ppm), 
Isopropyl Alcohol (200 ppm) and Carbon 
Dioxide (5000 ppm). Values measure gas and 
vapor concentrations in parts per million.
 
Required Alarm Levels: 
 
Before 10% COHb 
exposure at levels of 30% to 70% Relative 
Humidity (RH):
•400 ppm CO between 4 and 15 minutes
•150 ppm CO between 10 and 50 minutes
•70 ppm CO between 60 and 240 minutes
The unit is designed not to alarm when exposed 
to a constant level of 30 ppm for 30 days.
 
Audible Alarm: 
 
85dB minimum at 10 feet
 
Power: 
 
Powered by 120V AC. When power 
is on, green light shines continuously. Digital 
Display: Dash lit by READY.
 
Display Accuracy: 
 
Accuracy is +100% -40% 
of actual concentration of CO at 50% RH +/-
5% RH and 73˚F +/- 4˚F (23˚+/- 2˚C).
 
Peak CO Reading: 
 
Digital Display shows the 
highest level of CO (ppm) detected since the 
Peak memory was last cleared. 
 
Malfunction: 
 
Yellow light shines continuously. 
Red light flashes. Horn chirps twice a minute. 
Digital Display will read “Err”.
 
Dimensions: 
 
5.83" x 3.32" x 1.6" (Approx.)
 
Supply Voltage: 
 
120V AC 60Hz
.085A Standby .087A Alarm
 
During Alarm: 
 
COAlarm horn sounds while the 
red light flashes rapidly. Digital Display: Shows 
CO levels in ppm.
 
Warranty: 
 
5-year limited warranty.
 
Standards: 
 
Underwriters Laboratories Inc. 
Single and Multiple Station carbon monoxide 
alarms UL2034.
According to Underwriters Laboratories Inc. 
UL2034, Section 1-1.2: “Carbon monoxide 
alarms covered by these requirements are 
intended to respond to the presence of carbon 
monoxide from sources such as, but not limited 
to, exhaust from internal-combustion engines, 
abnormal operation of fuel-fired appliances, 
and fireplaces. CO alarms are intended to alarm 
at carbon monoxide levels below those that 
could cause a loss of ability to react to the 
dangers of Carbon Monoxide exposure.”This 
CO Alarm monitors the air, and is designed to 
alarm before CO levels become life threatening. 
This allows you precious time to leave the 
house and correct the problem. This is only 
possible if alarms are located, installed, and 
maintained as described in this manual.
