flowing.
• Normally Close/N.C: When no control signal is received, the electricity continues flowing. When control signals are received, the electricity does not
flow.
• Take care of the direction of the diode.
• Make sure to install the diode near to the door lock.
• Make sure to use different power supplies for the BioEntry Plus and the door lock.
• Make sure to install the diode at both ends of the circuit as shown in the figure above in order to protect the relay contact from the reverse current that
occurs when the door lock works.
