MOUNT THE MODULE
The module can be mounted in a DMP enclosure using the
standard 3‑hole mounting pattern. Refer to Figure 2 as needed
during installation.
1. Hold the plastic standoffs against the inside of the enclosure
side wall.
2. Insert the included Phillips head screws from the outside of
the enclosure into the standoffs. Tighten the screws.
3. Carefully snap the module onto the standoffs.
WIRE THE MODULE
2
Use 18 to 22 gauge wire to connect the 712‑8 directly to the
Keypad Bus or use a dual‑ended 4‑wire harness to connect
directly to the LX‑Bus. This connection allows the module to
communicate with the panel and receive 12 VDC power. For more
information about wiring, refer to Wiring Specifications. Refer to
Figure 3 when wiring the module.
Connect to the LX‑Bus
1. Place a jumper across the top two KEYPAD/LX‑ BUS pins.
2. Connect one end of a 4‑wire harness to the top header on
the module.
3. At the panel, connect the other end of the 4‑wire harness
to the LX‑Bus.
Connect to the Keypad Bus
1. Place a jumper across the bottom two KEYPAD/LX‑ BUS
pins.
2. Connect a 4‑wire harness to the top header on the module.
3. At the panel, connect the wires to the corresponding
Keypad Bus terminals.
