490-0463/A Carbon Monoxide Detector

Question: My 490-0463A goes off occasionally, about every other day; what can cause this?

Answer: False alarms can be caused by a low battery. However, the detector could be picking up a sporadic carbon monoxide condition. As carbon monoxide hazardous conditions can result from a variety of sources, you should check for the following:

Corroded or damaged appliances.
Malfunctioning parts or equipment.
Blocked exhaust draft heads or poor ventilation intake vents (insufficient oxygen to allow complete combustion of fuel).
