(adsbygoogle = window.adsbygoogle || []).push({}); Whenever a family member walks past the detector it goes off for a few seconds. It stops after, but is this ok? No one in my family is a smoker. Thank you for any advise/help.

Thought about changing the battery's at all? Mine was beeping every now and then for a few weeks and I never knew what it was.

You could alway buy a new one. Better safe than sorry

Might have a sensor telling you it's there.?

How old is it? If it's old, might just need to buy a new one.
