GFE DHA Isolator
The unit is a loop-powered addressable magnetic door release. It is directly powered from the loop and therefore doesn’t require external supply. Activation of the unit is achieved using cause and effect programming as used for I/O unit.
A built-in loop isolator is provided. When a short condition exists in either side of the loop connections, a yellow LED will be turned ON. Its operation will be reset after the fault condition is removed.
The activation of the GFE-DHA-ISOLATOR module can be achieved as part of the cause and effect programming of the panel and it operates in the same way as an I/O unit. This unit should normally be assigned to either a specific device or a specific zone.
