I'm getting ready to wire my smokes and I'm not clear on how to get
them all to sound when one goes off. Here's what I'm planning; please
help me understand how to hook up the reversing relay. (Note model
numbers in parenthesis are System Sensor)
18 System Sensor i3 series 4-wire smoke detectors with sounders
(4WTA-B) each on a separate zone connected to a OmniProII panel. Each
smoke will require its own EOL relay (EOLR-1).
As I read the manuals, it appears that I'll need a reversing relay
(RRS-MOD) for each zone, for a total of 18. Is that correct? How do
the reversing relays get chained together? Or should these connect to
the alarm output? For that matter, can the smoke alarms be used as an
auxillary alarm for a break-in or is that a no-no?
Thanks!

18 zones for fire?
smokes as aux alarm for intrusion?
you ever do this before?

very easy to diagnose. We have a 5000 sqft house and the layout is
such that 18 detectors is appropriate using the placement guidelines
supplied by System Sensor. Sure, I could zone a few of them in the
hallways, but again, each on its own seems much more simple (expansion
boards are cheap). Reviewing my post, I guess it is 14 of the
detectors listed plus three heat only plus one optical detector (for
end-to end coverage along the peak of a 30x60' great room with a 24'
high barrel vault ceiling) for a total of 18.
As for the aux alarm - I was just curious... figured the more noise the
merrier. Not to mention I suggested that I figured it was a no-no.
Have I ever done this? Nope. I do know that I'll figure things out
and the final result will be a quality installation. I'll also run all
of my final designs by the home automation and security company I'm
working with, but I prefer to do the research on my time since I'm
paying them on a consulting basis. They don't normally work this way
but I'm "not an average DIY'er" (their words). In our (very small)
town, we have electrical inspections only and I've got a friendly
relationship with the inspector and working through things with him.
I'm also talking to the local fire department about the setup as well.
Having lurked in this group over a year and having read a lot of
historical posts, I figured getting a worthwhile response was about
50/50. My worst fear is that Robert Bass will reply, four people will
quibble over some local jurisdiction detail and then the whole thing
will be derailed with something about Bass being wanted by the FBI,
MI-6 and the Florida BBB /sarc.
Constructive feedback appreciated!

which case you'll need 6 conductors at each detector rather than 4. As far
as conductor size, with 18 interconnected sounders, you should consult with
the manufacturer for the wire size required for your total wire length and
number of detectors. 18 guage fire rated wire is spec for the detectors- I
don't know what is spec for your sounders. You're on the right track with
EOL resistors and power supervision modules at each detector.
For what it's worth, if you could find Multiplex addressable detectors
(instead of 4-wire) that work with your system, it would be SO much easier
to configure and install, and probably cheaper. That way, you retain the
ability to know exactly which smoke tripped, but eliminate a great deal of
extra home-run wiring, relays, zone expanders, and power supv modules, and
probably the need to physically interconnect the sounders. Multiplex wiring
is a wonderful thing for any large alarm installation, for both fire and
burg devices.
No, you shouldn't use the smoke sounders as aux signaling devices- use your
smoke sounders as they are intended- fire alarm only. For a house that big,
I would use an supervised Aux power supply, triggered from the alarm panel
output, driving 1 or 2 "talking" siren drivers, which in turn drive 2 to 4
siren-speakers each in appropriate places throughout the home.
Here's a link to a good "talking" siren driver-
