stuff snipped

The wired smoke detectors in my house are not high pitched at all and
I'm sure the builder didn't pay more then a small amount for them.
They make a loud buzzing sound, sort of like the emergency broadcast
sound you probably have heard on your TV and radio.

Would you mind telling me (if you can reach them) what make and model they
are? Are they hardwired 110VAC or battery powered? Thanks!
