Addressable Magnetic Door Holder
GFE-DHA
Addressable Magnetic Door Holder
The unit is a loop powered addressable
magnetic door release. It does not require
external supply as it is directly powered from
the loop.
Activation of the unit is achieved using cause
and effect programming as used for I/O units.
If power is removed or communication with
the panel is lost the unit will release
automatically after approximately 20
seconds.
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.
Module is fitted with 3 status leds. The GREEN
LED will flash every time the device is polled
by the addressable panel.
The RED LED, when ON, indicates that the
door release has been activated and it is OFF
after panel power up or reset. When flashing,
it indicates that the door holder is ready to
release. Finally the YELLOW LED will indicate a
fault in the module.
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
added to an IO group and assigned to either a
specific device or zone.
Up to a maximum of 20 of these units can be
fitted on a particular loop.
