My AC smoke alarm specifically says not to make changes to it, but I
connected a relay coil across the buzzer, and I used the contacts as
part of my burglar/fire alarm system, first to set off the alarm,
steady instead of wailing, and soon it will notify a monitoring
service.

If I have messed up the alarm and I die in a fire, I have in my will
that my estate should sue me.


Details on exactly how you did it, what kind of relay (serial number?),
etc, crude schematic (via your website), etc?

Thanks!
