My smoke detector keeps chirping and beeping. Why does my smoke alarm chirp intermittently?
It is likely that the reason your smoke detector keeps chirping and beeping is that the battery is low. Whenever your smoke detector keeps chirping, replace the battery immediately. • A different device or appliance such as a security system, monitor, carbon monoxide alarm, or other device which has a similar low battery or alert signal. • Some of the same factors that cause unwanted alarms can cause intermittent alarms: dust and insects in the detector or power interruptions in hard wired detectors. • Improper wiring on AC or AC/DC smoke alarms. AC alarms will chirp every 5 seconds if the interconnect wire is grounded. The orange interconnect wire should NEVER be grounded; it should only be used to interconnect other smoke alarms or compatible devices.
