I have a NFS-320, we have programmed in a module that is connected to a keyed switch. We have figured out how to disable out the NAC signal for a particular zone, but i would like to disable it completely. When I say completely, I dont want any device in the zone to send any sort of signal to the panel.
issue now is that our panel still lights up a fire alarm red led light and has a local alarm inside the panel go off. It also engaged the alarm latching circuit which we use for calling out a notification to personnel.
Being that this is an addressable panel the only way would be to cut communication through the slc loop which would put the panel into trouble. So the only way to disable it completely would be through programming.
you will need little more than a key switch to do that, still is a fire alarm system that will try to inform you if something is not in the normal state, can try with an annunciator, ACM-24AT is the best that can suit your needs. better turn it off if you want 100% “disabling”
Yes, that should work. I don’t usually use any of the default zones and create my own zoning startiing at zone 10. Do you want to disable the smokes and the NAC, or just the NAC? You may need to use CBE 2 to do this instead of CBE 1.
