Automatic Gate
The Door Lock Relays can be used to activate an automatic gate operator when a user is granted access.
1. Route two wires between the gate and the unit.
2. Connect the gate operator’s OPEN terminals to the unit’s DOOR LOCK RELAY COM & NO terminals.
NOTE: For operator wiring specics, refer to the gate operator’s wiring diagram. See Recommended Wiring Requirements, pg. 12, for proper
gauge requirements.
Mag Lock
1. Install a low voltage electric magnetic lock as a locking device for the door or pedestrian gate.
2. Install the power supply or transformer for the locking device. DO NOT POWER THE UNIT FROM THIS POWER SUPPLY.
3. Connect one wire from the power supply to one wire from the locking device.
4. Route two wires between the locking device and the unit. Connect one wire to the remaining wire of the locking device. Connect the other wire
to the remaining wire of the power supply.
5. Install a protection diode (for DC mag locks or MOV for AC mag locks) across the mag lock to protect the door relay contacts.
6. Connect the wires to the unit’s DOOR LOCK RELAY COM & NC terminals for fail secure operation or DOOR LOCK RELAY COM & NO
terminals for fail safe operation.
NOTE: For fail secure operation with a magnetic lock, the lock’s power supply must have battery backup to power the lock during a power
failure. Be sure to comply with NFPA and local building code requirements.
