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.
