Step 3: Mount the backplate
1. Loosen the two screws located
along the bottom edge of the
keypad, and then remove the
front cover.
2. Secure each corner of the
backplate (Figure 2) and each
back-tamper breakout (Figure 3)
to the wall.
Note: To ensure correct fitting, it is
essential that the backplate is flat,
otherwise tamper faults may occur.

Each back-tamper contains a
graphite disc. When the cover is
closed, the graphite discs touch
contacts on the PCB to close the
tamper connections.

Connect all wiring to the terminal
board (Figure 4). The only
mandatory connections are to the
