Wire the Magnetic Lock
The 734 provides a Form C (SPDT) relay for controlling locks and other
electronically‑controlled barriers. The three relay terminals marked NO C NC allow
you to connect the device wiring to the relay for module control.
Use an additional power supply to power magnetic locks and door strikes. See
Figures 3 and 4 for typical magnetic lock and door strike wiring.
The Form C relay draws up to 35mA of current and contacts are rated for 10Amps
(resistive) at 12/24VDC. When connecting multiple locks to the Form C relay, the
total current for all locks cannot exceed 10Amps. If the total current for all locks
exceeds 10Amps, problems may arise and an isolation relay may be needed. See the
Isolation Relay section for information.
