Hello
I surveyed to take over an existing 22 door Paxton access control system & I noticed that there were one of these white plastic boxes over nearly every door that was wired up to the system. I have done some research online & they seem to be part of the fire alarm to monitor the sounders however could they be connected to the door Maglocks to unlock upon the fire alarm activating?
I'm not experienced at all in fire alarms & hoped that someone can help please.
Thanks
