Smoke alarms ( hard wired )
Are the alarms accessible in the sense that you can vaccum up dust, etc from
them ? I have read that dust and debris buildup can cause alarms to go
off.
I would also give them a "test", using a match (with the hot flame), and
then ten minutes later, test them again with smoke, to see if they go off.
If you are not absolutely sure, just replace them.
