HOW YOUR CO ALARM WORKS

 

General Information

CAUTION!

 

Leave your CO Alarm plugged in year-round. 
CO problems can occur any time during the 
year, and this alarm can only alert you if it is 
plugged in and receiving power. 

 

This CO Alarm is intended for use in a standard, 
unswitched 120V AC wall outlet. It is not 
intended for use in extension cords, power 
strips, or outlets controlled by a switch or 
dimmer. These may not provide continuous 
power to the unit. 

When fully powered, it samples the air and 
takes a new reading about every second. A 
microchip inside the unit stores each reading, 
and remembers the levels of CO it has been 
exposed to over time. The unit goes into alarm 
mode when it has been exposed to a “critical” 
level of CO (measured in parts per million or 
“ppm”) within a specified time (measured in 
minutes). 

This Carbon Monoxide Alarm features a 
permanently installed sensor, three colored 
indicator lights, and an 85 dB alarm horn. It 
also has a silence feature to temporarily quiet 
the alarm horn.
