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 1,000 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).
Operation
The Class A, Style D circuit consists of a 2-wire zone out to the protective devices and a 2-wire return from the last
device to the module. In the event of an open condition on the circuit, devices on either side of the fault could still
initiate an alarm. During an alarm (shorted) condition on either Style D zone, the module shorts the panel alarm zone
to ground. During a trouble (open) or ground fault condition on either zone, the module opens the panel alarm zone. In
addition, ground fault conditions on either Zone A or Zone B light the corresponding red LED.
