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
When exposed to a constant level of 30 ppm of CO,
this CO Alarm was tested not to go into alarm for at
least 30 days.
Audible Alarm: 85dB minimum at 10 feet.
Power: Powered by 120VAC. The 9V battery back-up
provides 8 hours of standby and sounds alarm for 12
hours with fresh battery. When AC power is on, red
light (LED) shines continuously. Under battery power,
red light flashes once a minute.
Malfunction: Horn chirps and light blinks 3 times (in
rapid succession) every minute and digital display
shows “Err”.
Dimensions: 5.4” diameter (approx.)
Supply Voltage: 120VAC 60Hz, 0.09A.
During Alarm: Repeating alarm horn pattern:
4 beeps, pause, 4 beeps, pause.
• Stand-alone unit: red light (LED) flashes once
per second.
• Interconnected series: red light (LED) flashes
once per second on the Initiating alarm. The
red light (LED) on all other alarms will shine
continuously.
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.
