712-8 ZONE EXPANSION MODULE
Installation Guide
DESCRIPTION
MODEL
712-8
The Model 712‑8 Zone Expansion
Module allows you to increase
the number of protection zones
available on a DMP panel. The 712‑8
provides a total of eight grounded
zones.
The zone expansion module
provides a terminal strip for zone
inputs, two 4‑pin headers for
Keypad Bus or LX‑Bus connections,
a jumper for LX‑Bus or Keypad Bus
operation, and a transmit data LED
to indicate panel communication.
Note: The 712‑8 is listed for use in
burglary applications only: No fire
circuits shall be used on this device.
Compatibility
• XT30/XT50 Series panels
• XR150/XR550 Series panels
What is Included?
• One 712‑8 Zone Expansion
Module
• Eight 1K Ohm EOL resistors
1MOUNT 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 standos against the inside of the enclosure
side wall.
2. Insert the included Phillips head screws from the outside of
the enclosure into the standos. Tighten the screws.
3. Carefully snap the module onto the standos.
WIRE THE MODULE
2Use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.

3To communicate the status of the eight zones, the module
responds to two addresses on the Keypad Bus and eight
addresses on the LX‑Bus. You can set the module starting
address to any bus address from 0to 15. The module
automatically responds to this address, the next address
on the Keypad Bus, and the next seven addresses on the
LX‑Bus.
To change the current address, move the slide switches to
the appropriate address positions according to Figure 4.
Keypad Bus Addressing
The module can be set to the following keypad addresses
according to panel model: 1through 8for XT30/XT50
and XR150 Series panels, or1through 15for XR550Series
panels. Additionally, the eight zones on the module occupy
two keypad addresses.
For example, if the module is set to address2, the first four expansion zones occupy address 2and respond
as zones 21‑24. The last four expansion zones occupy address 3and respond to the panel as zones 31‑34. For
more information about Keypad Bus addressing, refer to Table1.
Note: Because the 712‑8 is supervised, both addresses must be selected in Device Setup of the
XR150/XR550Series programming when used on the Keypad Bus.
LX‑Bus Addressing
When connecting to the LX‑Bus, the module must be addressed to match the last two digits of the
first zone being used. The next seven zone addresses are automatically used to communicate expander
zones2through8status.
For example, on an XR150panel using LX‑Bus 1if you set the module address to8, the eight zones on the
expander respond as zones 508to 515. When connected to an XR550panel using LX‑Bus 2, the zones respond
as 608to 615. For more information about LX‑Bus addressing, refer to Table2.
Note: Only two 712‑8 Modules can be connected to each LX‑Bus.

ADDITIONAL INFORMATION
Wiring Specifications
DMP recommends using 18 or 22 AWG for all LX‑Bus and Keypad Bus connections. The maximum wire distance between
any module and the DMP Keypad Bus or LX‑Bus circuit is 10 feet. To increase the wiring distance, install an auxiliary
power supply, such as a DMP Model 505‑12. Maximum voltage drop between a panel or auxiliary power supply and any
device is 2.0 VDC. If the voltage at any device is less than the required level, add an auxiliary power supply at the end of
the circuit.
To maintain auxiliary power integrity when using 22‑gauge wire on Keypad Bus circuits, do not exceed 500 feet. When
using 18‑gauge wire, do not exceed 1,000 feet. Maximum distance for any bus circuit is 2,500 feet regardless of wire
gauge. Each 2,500 foot bus circuit supports a maximum of 40 LX‑Bus devices.
For additional information refer to the LX‑Bus/Keypad Bus Wiring Application Note (LT‑2031) and the 710 Bus Splitter/
Repeater Module Installation Guide (LT‑0310).
Connecting to Other Modules
Using a 4‑wire connector as an extension of the Keypad Bus or LX‑Bus, you can easily connect the 712‑8 to multiple
modules on the same bus. Observe wire colors when making connections. For more information about wiring
connections, refer to Figure 3.
Data LED
The LED on the 712‑8 flashes each time the module responds to a poll from the panel. If there is a problem with the
panel, system programming, or the connection between the panel and module, the LED stops flashing and a system
trouble message displays on the keypad.
Compliance Listing Specifications
UL Commercial Burglary
The 712‑8 Zone Expansion Module must be mounted inside the control unit enclosure or other Listed enclosure.
ULC Commercial Burglary (XR150/XR550 Series Panels)
If the 712‑8 is installed in another enclosure, a DMP Model 307 Clip‑on Tamper Switch programmed as a 24‑Hour zone is
required.
The 712‑8 zones can only be used in Low Risk applications. Medium or High Risk applications must use panel zone
inputs.
