GFE DHA V2

Loop powered addressable magnetic door holder. It does not require external supply as it is directly powered by the loop. The activation of the unit is achieved using cause and effect programming as used for I/O units.

The module is fitted with 3 status LEDs. The Green LED will flash slowly when the battery is charged, and flash faster when the battery is in charge mode. The presence of this LED also indicates that the device is polled by the addressable panel. The Yellow LED indicates that the isolator is active (short circuit in the loop cables). 

The  combination between the Green and Red led returns several status informations decoded in a table.

The activation of the 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 zone. Up to a maximum of 20 of these units can be fitted on a particular loop.
