Main Power supply for the control unit

Dry contact means no voltage is provide by ekey system on the relay. Form C contacts are also called

changeover contacts that have three contacts as follows:

1. (C) Common = common leg of the circuit

2. (NO) Normal Open = default relay is open meaning the circuit is open not complete; relay will close to

complete the circuit when a valid fingerprint match is found. For example, this option is used when

controlling door with electrical strike in Fail-Secure mode. In this scenario the door is closed when the lock

has no power. When a valid fingerprint match is found, the relay is closed causing the lock to energized

leading to the door to set open.

3. (NC) Normal Close = default relay is closed meaning the circuit is closed and complete; relay will open to

break the circuit when a valid fingerprint match is found. For example, this option is used when controlling

door with Magnetic Lock or electrical strike in Fail-Safe mode. In this scenario the lock requires power to

magnetize and hold the door close. When a valid fingerprint match is found, the relay is opened causing the

lock to lose its power and demagnetized leading the door to set open.
