HAI OPII 4-Wire Smokes and Z1-4

[bluelake321]

HAI OPII specifications state:



I had already used zones 1-4 so went to the expansion board using the last group of zones that I had available. Bought a second expansion board as I will be needing but haven't installed it yet.

I went with separate zones (EOLs) and one polarity reversal module for smokes and one for CO detectors.

I was initially confused until I saw the drawing that was posted.

Here's some more with specifics.

Smokes Z 5 plus

What did you use to trigger the reversing relay(s)? As there is not a dedicated alarm sounder for fire, did you just program one of the outputs to close upon a fire event?

I went with my drawing. That said I removed all when I moved and never configured the smokes afterwards.
