Please NOTE:

1. The maximum current outputted by the door lock relay on the fingerprint is less

than 5A. If the current for door lock exceeds the capacity, an external power relay

is needed.

2. V+ in the figures represents one lead of power from an external power source.

When using DC Voltage for the lock, put the positive lead here. When using AC

the leads are interchangeable.

Connection to Request-to-Exit

When fingerprint controller receives a valid signal (closed connection) from the request-to-exit

device, like a button, the controller will unlock the door for the specified open time. Connect

the request-to-exit device to terminal 12 and 13, shown as the below figure:

Fig. 9. Connecting REX to Controller

Connection to Door Sensor

Door sensor presents the door status, i.e. if it is open (open circuit) or closed (short circuit).

Connect the two wires from door sensor to terminal 14 and 15 of fingerprint controller, shown

as the below figure:

Connection to Alarm Input

Fingerprint controller supports 4 general alarm inputs, for example, a motion sensor or a glass

sensor. Normally the 4 alarm inputs can represent 4 arm zones, but they can be freely defined

based on the actual application. When a valid alarm input (closed circuit) is detected, the
