Question About BRK electronic Smoke Alarm 4120B
Alarm goes off all night long...

Our alarm goes off frequently all of a sudden. Last night it went off about every hour for no apparent reason. We have vacuumed them! But to no avail. They've been in the house for 12 years so I don't think location is the issue
