Relay Connection – Dead-Bolt Type Door Lock
There are two types of dead-bolt door lock connections and configuration supported – fail-safe
and fail-secure.
• Use different power supplies for the NovaFace and the door lock.
• Install the diode at both ends of the circuit as shown in the figure below
close to the door lock to protect the relay contact from the reverse current
that occurs when the door lock works.
• Make sure that the diode direction is correct.
