I use to think that most fire doors were 'fail' safe, meaning if the fire alarm/or door looses power then the door would still close.
I had been trouble shooting a fire door circuit and its a more modern one, with a 'circuit board for most of the controls. Im used to the old types with out the board.
originally the problem was the 'safety edge' strip wasnt working, its what makes the door go back up if it was comming down on an obstructions. Its adjustable (air switch, Ive done them before). Tried adjusting it, (to make it more sensitive) and now the motor clutch break engages, and you cant move it up or down with the controls, and it gives out a loud whistle, (I dont believe its an alarm).
I put the settings back to the original setting, and still no control. Turned off power(disco switch) to try to reset. still no go.
I believe the cirucit board is bad. Just looking for other options, cause this board is gonna be costly. I know the old ones without them are easy to fix and less expensive.
Any ideas???
