Normal Operating Characteristics
When you first power up the alarm, the red alarm light will
come on and the alarm will sound briefly, then the green operate
light will come on. This is to show that the CO alarm is receiving
power and that the alarm circuit is functioning.
Within a few minutes, your carbon monoxide alarm will start moni-
toring for CO and will continue to do so as long as it receives
power.
Do not install CO alarm near deep cell large batteries. Large bat-
teries have emissions that can cause the CO alarm to perform at
less than optimal performance.
The following conditions can result in transient CO
situations:
• Excessive spillage or reverse venting of fuel burning
appliances caused by outdoor ambient conditions, such as:
1) Wind direction and/or velocity, including high gusts
of wind. Heavy air in the vent pipes (cold/humid air
with extended periods between cycles).
2) Negative pressure differential resulting from the use
of exhaust fans.
3) Simultaneous operation of several fuel burning
appliances competing for limited internal air.
4) Vent pipe connections vibrating loose from clothes
dryers, furnaces or water heaters.
5) Obstructions in or unconventional vent pipe designs
which can amplify the above situations.
• Extended operation of unvented fuel burning devices
(range, oven, fireplace, etc.).
• Temperature inversions which can trap exhaust gasses near
the ground.
• Car idling in an open or closed attached garage, or near a
home.
