Connection with Lock

Connect the lock with 12V power, NC1 and COM1 into a loop, as follows:
Notes for wiring:
In order to avoid the influence of the self-induced electromotive force produced by the electric lock on the access
control system, a diode in parallel need to be connected on the electric lock, when the access controller is connected.
Select FR107 diode with a faster response speed. FR107 diode has positive (shown as "+" in the figure) and negative
(shown as "-" in the figure) poles. At the time of wiring, connect the "+" of diode to the "-" of electric lock and the "-"
of diode to the "+" of electric lock. Keep the diode as close as possible to the electric lock.
