Anyone know anything about smoke detectors?

[no one]

The Grand Nudger:
Don't ask the internet for advice on your fire alarm. If it's not a battery issue, it's a failure indicator. The tone should be lower and it won't have the same pattern as it does when it detects smoke. There's a super annoying way to test this which involves setting off your detector, resetting your detector with brand new high quality backup batteries...then testing the batteries charge when it goes off - as well as the tone.

But....... you shouldn't be asking the internet for advice about your malfunctioning fire alarm. You should have it professionally serviced by factory trained technicians...or replace it.



The sense is this post......I suspect might completely break Fernando.
