ABK-703B-S: connection diagram with an Access Control device

Among the possible configuration options indicated in the product's manual, we explain the first and most intuitive one.

For the lock to open, we have to make a bridge between L- and GND and connect the positive pole of 12V to L+; in order to achieve this, in the access control device we will make a bridge between +12V and COM, and we will link NO to the L+ of the lock.

In this way, when the relay of the Access Control device is activated, the 12V impulse will reach the L+ connector and the lock will be opened.
