Why is my fire alarm going bad if there's no fire?
Check your battery. On some fire alarms the last wheeze of battery life is used on making your natural life heck. Try that. the batteries might be low or the fire alarm needs to be replaced,
If it is of late doing the occasional beep, it is probably your battery.
If it is going bad, check your oven/stove for anything burning; if you smoke, this could set it off. Check to see if this is a combination smoke/carbon monoxide detector. If it is both, you could have soaring levels of Carbon Monoxide in the heavens, and should have this checked out immediately.
But, hopefully, ya only just need a new battery-operated for the little noise maker!
Stay secure!
Answers: If yours are hard wired like mine near battery back up, sometimes you hold to clean them. I vacuum mine, but electrical dust, grease and grunge collect in them and have to be cleaned out. Dish soap and water or any commercial spray cleaner works. I think the little nouns holes get clogged and heat builds up inside to variety the detector go off.
