Thanks for your input, Mr. Morgan.
You're welcome.

Another option is to use an off-the shelf detector with auxiliary
contacts
built-in. They are far for common and much less expensive than the
unit
you're
mentioning. You can then trigger any device you want (UL listed for
fire or
not) to make the appropriate signal tone.

I think there are relays that are intended (UL listed) to be used with
some 3-wire smoke alarms (where all alarms go off). The relay would
give
you auxiliary contacts.

Any specific items to recommend?


From Kiddie:

The way I read the site is if you have smoke alarms and CO detectors
wired together to common-alarm, one relay module will alarm only for the
smoke detectors and one relay will alarm only for CO detectors.

Some other smoke alarm manufacturers must have similar relays.

Thanks, Bud - I'll look into it.
