Addressable Loop Powered Door Magnet (ZTA-DH)
The Loop powered door magnet unit consists of a controller uni, which connects directly to the loop, and a permanent magnet door holder. The door holder controller can then be programmed to operate in a similar manner to an input / output unit.
The current consumption allows the use of up to 20 units per loops.
It has a manual door relase button to allow the magnet to release the door at any time.
The interface also has a built in loop short circuit isolator, to help maintain system integrity in the event of a fault condition.
