@alphatechalarm: Your smoke alarm isn't haunted. That chirp usually means low battery or the unit's at end of life. Swap the battery, check the date on the back, and if it's past its replacement date, replace the whole thing. You're welcome. 😴 Need help with a commercial system? We do that every day. 661-834-8324 #FireAlarm #SmokeDetector #FireSafety #Bakersfield #AlphaTechnologies AI-generated video.
