Relay connection
Fail Safe Lock
In order to use the Fail Safe Lock, connect N/C relay as shown in the figure below. There is normally a current flowing through the relay for
the Fail Safe Lock. When the relay is activated, blocking the current flow, the door will open. If the power supply to the product is cut off due
to a power failure or an external factor, the door will open.
•
Install a diode at both sides of the door lock wire as shown in the figure to protect the relay from the reverse current, which occurs when the door
lock operates.
•
Take caution of the installation direction of the diode. Install the diode close to the door lock.
•
Use a separate power supply for BioEntry W2 and the door lock.
Fail Secure Lock
In order to use the Fail Secure Lock, connect N/O relay as shown in the figure below There is normally no current flowing through the relay
for the Fail Secure Lock. When the current flow is activated by the relay, the door will open. If the power supply to the product is cut off due
to a power failure or an external factor, the door will lock.
