710 Bus Splitter/Repeater Module
Description
The 710 Bus Splitter/Repeater Module expands the typical LX-Bus™, Keypad bus or Wireless bus installation both
in the number of devices and the length of wire used. The 710 Bus Splitter/Repeater Module is suitable for listed
burglary and fire applications.
As a splitter, the 710 provides superior mechanical wire connecting capability for up to three additional 12 VDC
LX‑Bus or Keypad bus circuits. This makes the 710 module an excellent junction box when terminating multiple
LX-Bus/Keypad bus runs at one location. As a repeater, the 710 module can be installed at the end of an LX-Bus or
Keypad bus circuit to allow the addition of a circuit to increase the total wire length.
Wiring Specifications for Keypad and LX-Bus
Several factors determine the performance characteristics of the DMP LX-Bus and Keypad bus: the length of wire
used, the number of devices connected, and the voltage at each device. When planning an installation, keep in mind
the following four specifications:
1. DMP recommends using 18 or 22-gauge unshielded wire for all keypad and LX-Bus circuits. Do not use twisted
pair or shielded wire for LX-Bus and keypad bus data circuits. All 22-gauge wire must be connected to a
power-limited circuit and jacket wrapped.
2.On keypad bus circuits, to maintain auxiliary power integrity when using 22-gauge wire do not exceed 500
feet (152.4 meters). When using 18-gauge wire do not exceed 1,000 feet (304.8 meters). To increase the wire
length or to add devices, install an additional power supply that is listed for Fire Protective Signaling, power
limited, and regulated (12 VDC nominal) with battery backup.
Note: Each panel allows a specific number of supervised keypads. Add additional keypads in the unsupervised
mode. Refer to the panel installation guide for the specific number of supervised keypads allowed.
3. Maximum distance for any one bus circuit (length of wire) is 2,500 feet (762 meters) regardless of the wire
gauge. This distance can be in the form of one long wire run or multiple branches with all wiring totaling
no more than 2,500 feet (762 meters). As wire distance from the panel increases, DC voltage on the wire
decreases. Maximum number of LX-Bus devices per 2,500 feet (762 meters) circuit is 40.
4. Maximum voltage drop between the 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 to the circuit. When voltage is too
low, the devices cannot operate properly.
For additional information refer to the panel installation guide and LX-Bus/Keypad Bus Wiring Application Note (LT-2031).
Maximum Circuit Distance for Data
The maximum cumulative distance for wiring on one
LX-Bus/Keypad bus circuit is 2,500 feet (762 meters), regardless of the wire gauge. This distance can be in the form
of one long wire run or multiple branches with all wiring totaling no more than 2,500 feet (762 meters).
See Figure 1.
Maximum Number of Devices per Circuit
Install up to 40 devices on every 2,500 feet (762 meters) of wire. The device number can increase up to 50 devices if
the wire run remains less than 2,500 feet (762 meters).

Maximum Voltage Drop
The maximum allowable voltage drop between the panel and any device connected to the LX‑Bus or Keypad bus is
2.0 VDC. A voltage drop example is when the voltage across the red and black wires at the panel reads 13.8 VDC, the
voltage measured at each device must be equal to or greater than 11.8 VDC.
If the voltage at any device, including a 710 module, is less than the required level, add an auxiliary power supply to
the circuit. Increasing the wire gauge used on the circuit can reduce the voltage drop. The maximum voltage drop
rule applies to LX-Bus circuits and Keypad data bus circuits powered either by the panel or by an auxiliary power
supply.
Note: To troubleshoot voltage drop, read the voltage at the last device on the LX-Bus or Keypad bus.

710 Installation Guide
Multiple Circuits
In this example the first 710 module is in close proximity to the panel. At this point, the 710 is used to branch the
LX-Bus/Keypad bus into three separate circuits. Each of these circuits can be run a distance of 2,500 feet (762
meters). At the end of the 2,500 feet (762 meters), install another 710 module to add another 2,500 feet (762
meters) of LX-Bus/Keypad bus capability.
See Figure 4.
Note: The total combined distance of all circuits cannot exceed 15,000 feet (4572 meters).

Additional Use of the 710 Module
The 710 module is an ideal device to add to the
LX-Bus/Keypad bus circuit close to any large
grouping of devices. The 710 makes wiring
multiple devices easier by providing a means to
connect three separate wire runs to the main
LX-Bus or Keypad bus. In this application, wire
nuts or other mechanical connectors are not
required as all wiring terminates on the 710
screw terminals.
