Hello, I’m new to the forum and I’m trying to resolve a programming issue that has me scratching my head.
I’ve got a FCI/Gamewall 7100 panel with multiple AOM’s set up to shutdown the HVAC AHU’s.
I’ve got two loops set up with AOM’s on 1-194, 2-192, 2-194, and 2-198. The AOM’s are setup as Type 39, non-silenceable output. The Outputs are then assigned to Group 7 which is set to General Alarm but NOT Supervisory.
However, anytime the panel goes into a Supervisory condition the AOM’s still engage.
Any idea why the AOM’s would not be responding to the proper Group conditions?
I did some more digging on this panel and found that the sprinkler tamper switch was assigned the same group # as the AOM group for the AHU’s.
So it has the appearance to me that any sensor / input device that is activated and is in the same group as an output device will basically link those two devices together regardless of the output programming for the group?
So it appears to me that I need to move the AHU AOM’s to a new group that is unused because it looks like the original programmer dumped virtually everything into the same group.
So I figured out the groups, I failed to recognize that the groups were set up to tie certain inputs to outputs, i.e. the elevator mechanical room heat/smoke detector ties back to the shunt-trip on the elevator power.
But here what I still don’t get, why if my group output was set to not respond to a Supervisory command was it still activating the AOM’s on supervisory conditions.
