caused by external conditions.
NOTE
•
Install the diode at both ends of the wire for the door lock device as shown in the figure to protect the relay from being damaged by
the reverse current induced when the door lock device operates.

Make sure that the direction of the installed diode is correct.
•
Install the diode close to the door lock device.
•
Use a separate power source for BioEntry Plus from the door lock device.
