Global Fire GFE DHA Addressed Magnetic Door Holder

Global Fire GFE DHA is an addressed magnetic door holder that keeps fire doors in the open position under normal conditions. Since it receives its power from the loop circuit to which it is connected, no separate power line needs to be run; the release command is given via cause-and-effect programming through the I/O contact. It has an internal isolator; the yellow LED lights on both sides of the line in case of a short circuit.
