INSTALLATION GUIDE 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). 2,500 Feet (762 meters) Panel 1,100 Feet (335 meters) 200 Feet (61 meters) Panel 1,200 Feet (366 meters) T-Tap Figure 1: One Circuit Maximum Distance 1,100 200 + 1,200 335 61 + 366 2,500 762 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. Keypad Bus without a Power Supply Voltage across red and black at all devices must be 11.8 VDC or greater. Voltage across red and black here is 13.8 VDC. Panel 11.8 VDC Minimum 11.8 VDC Keypad Bus Devices LX-Bus with a Power Supply Voltage across red and black here is 13.8 VDC. Do not connect the red wire between the panel and the first device when using an auxiliary power supply.

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). 2,500 Feet (762 meters) 710 Module 2,500 Feet (762 meters) Devices 2,500 Feet (762 meters) 2,500 Feet (762 meters) Panel 2,500 Feet (762 meters) 2,500 Feet (762 meters) Class B Style 3.5 Figure 4: Multiple Circuits Locating Optional Power Supplies Add auxiliary power supplies on the end of each 710 module circuit to meet the 2.0 VDC maximum voltage drop rule. 710 Module Power Supply Devices Devices Do not connect the red wire between the panel and the first device when using an auxiliary power supply.

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.
