Smoke detector and CO beeping without reason
Yesterday night one of the CO detector started to beep without reason (this after through checking the house) and then I changed the battery.
The beep did not stop and all other Smoke detectors and CO started to beep constantly--I did not smell any smoke, no fire, opened the windows and doors, no unusual usage of any appliances at that hour(2am).
My son pressed and held the test button of the CO for a while and then the beeping stopped!!! --just when I was above to call the cops.
What could be the reason? Whom should I contact? There is absolutely no fire, smoke or any kind of unusual thing things happening at home. Even now and then I hear one or two beeps.
