[Hai-users] AC Smoke Detector and HAI OPII

[Andrew Comstock]

I wish it were that simple.  Each manufacturer is different.  If you want to
do this, and I would discourage it, I suggest that you contact the
manufacturer of your smoke detectors for their "hearing impaired" kit.
Generally designed to activate a strobe light, not interface to a security
system.  It will be a relay of "sorts", and will be interpretted by the
innerconnected smoke detector network as another smoke detector.  I have had
bad experiences in the past with the Firex solid state relay.  The relay
itself can result in false alarms.  Having said that, I have not installed
one in about 3 years.

This will work, but it does not provide battery back-up or supervision.
Wherever possible, I would be installing 12VDC smoke detectors.  There are
models that can be innerconnected to meet the building code requirements.

I recently installed an HAI OmniPro II.  I want to be
notified if the standard 3-wire smoke detectors go off
in the house.  Does anyone know what happens to the
3rd wire of the AC smoke detector when the alarm goes
off?  Does the output voltage go to 120v?  I want to
put something like a relay on the supervision wire to
tie it into my panel. Please help!

Jason
