Door Control Module
Door Control Modules (DCMs) can be added onto the Galaxy bus lines to add fully integrated access con-
trol. Each DCM allows up to two Wiegand readers to be connected to control two separate doors; each door
with an exit button or one door with an entry and exit reader.

Access Control (cont’d)
NOTES:
1. If only one door is being connected, then always use the connections for Door 1 (Left Side) and
terminate the inputs with a 1K resistor.
2. When door readers are being connected for entry and exit to the same door, then connect the entry
reader to Door 1 and connect the exit reader to Door 2.
