HAI and Altronix with DSC 4 Wire Smokes----HELP

Hello All-

I am currently attempting to connect my smoke alarms, all 18 of them!

Here is the bill of materials:
HAI Omni Pro II with the latest firmware
Altronix AL300ULXR Power Supply
DSC Power Supervision Relay
DSC Polarity Reversal Module
DSC-FSA410BS Smoke Detectors

The house is divided into three zones, 1st, 2nd and 3rd floor.
All of the smokes are 4 wire.

My question is this:
What is the best way to connect everything?
The last detector in each zone has the power supervision relay wired in behind the smoke detector, but I am lost when it comes to the reversal module. Does each zone require a reversal if I want 3 zones on the Omni? I need all of the zones to alarm when one zone is triggered.

From a diagram I found on HAIs forum it looks like the green and yellow from the smoke go to an omni zone (5-16), red and black go to P- and P+ on the reversal module. In addition, the other wires on the reversal module are as follows-T2 to an output on the omni, GND and +12 to switched power.
Should I bring the GND and +12 to the Altronix DC +/-

Thanks!

I can at least answer the reversal question for you. You only need one per system no matter how many zones you break it up into.

Use the diagram and take your time. If you would like I can take pictures. I used two reversal modules; one for CO's and one for smokes.

Should I bring the GND and +12 to the Altronix DC +/-?

I'm not sure if on yours but mine is a DSC - and is labeled as follows: (I would say "yes" to your question)

(12VDC) - Going to OPII switched 12VDC
(GND) - Going to ground next to OPII switched 12VDC
(T1) - No connection
(T2) - OPII Output 1 (and second reversal one going to output 2)
(P+) - Smoke(s) (red)
(P-) - Smoke(s) (blk)
