Re: smoke detector wiring

["J Barnes" <trishnjames@xxxxxxxxxxx>]

You only need one RRS module on the smoke detector power wires.  Even though
you have zoned out the smokes they will all use the same power source so 1
relay is good.  You will need one end of line supervision relay for each
zone (18) of them.  The reversal relay should be wired to a fire alarm
bell/siren output.  I would not use the sounders in the smoke detectors for
burglary, although it is possible.
