Hi everyone, I have an old Faraday Mpc-2000 that had a bad smoke detector that we recently replaced. When we went to order a new one we were told that the original that was installed on the system (System Sensor 2251) was no longer made and had been only supplied to panel manufacturers at the time. The “like for like” replacement, that plugged right into the existing base was a Secutron 2251B. This detector functions correctly but has caused a trouble on the panel reading “MAINT TRBL” and we can’t get it to clear. I usually see Maint. troubles on a dirty detector/out of threshold and not sure if there is someway we need to hook up to the panel or go into programming to get it to reset. Is anyone familiar with replacing detectors on the Faraday MPC-2000? Could it be a firmware issue with the new detector?
The smoke detectors are the addressable rotary decade switch style.
One of the technicians says that there was a TST trouble on the nuisance detector that was replaced.
Also I’ve noticed that the base contacts are off by a few degrees from the new detectors but power, alarm, latching and reset have tested correctly.
Any and help ideas or help would be appreciated. Thanks,
Tyler
