Programming Wiegand Pass-Through Operation (Continued):
Setting Up an Interlock System with Two Keypads:
In this application, two keypads are each connected to separate door locks and egress
pushbuttons. While one door is open, the other cannot be opened. The user uses their user code
or fingerprint to open the first door, and then must wait till the first door has closed to enter their
user code or fingerprint to open the second door.
Wiring Diagram:
User ID Transmission Format:
The fingerprint reader/keypad will transmit the user code data when the key is pressed. The
transmission format is "Device ID,User Code" (5 digits allotted for user ID). However, if the user
code is more than 4 digits, the device ID is not transmitted. Note that the device will transmit any
input preceding the key, whether valid or not. See the following examples when the device ID is
255:
•
User code 5555 (4 digits), device output is 255,05555
•
User code 55555 (5 digits), device output is 000,55555
•
User code 555555 (6 digits), device output is 005,55555

NOTE:
For DC-powered electric strikes, connect the included diode as close as possible and in parallel
with the electric strike. This absorbs possible electromagnetic interference to prevent operation
of the strike from damaging the fingerprint reader/keypad. Do not connect a diode when using
electromagnetic locks or with AC powered strikes.
