With the backbox securely mounted in the wall opening:
1) Screw the 3 supplied studs into the 3 respective standoffs on the metal backbox
(Figure 1).
2) Place the plastic backbox into the metal backbox so that the back of the plastic
backbox sits flush against the metal backbox (Figure 2).
3) Screw the 3 supplied nuts onto the 3 respective studs:
• If the metal backbox is flush with the surface of the wall opening, screw the nuts until they
touch the standoffs.
• If the metal backbox is slightly behind the surface of the wall opening, screw the nuts so
that they are slightly suspended on the stud. The nuts may need to be adjusted to achieve
the proper fit.
4) Insert the 8-position modular connector of the network cable into the RJ-45 connector on the
door station, through the cutout in the plastic backbox.
5) If used, connect the controlled device and/or power supply to the relay outputs marked
R-NO/R-NC and R-COM.
