screw holes on each corner of the base. Before mounting the base, connect the keypad wire harness leads to the keypad
cable from the panel and to any device wiring run to that location. Then attach the harness to the pin connector on the PC
board, mount the base, and install the keypad cover making sure all of the keys extend through their respective holes.

The base provides you with mounting holes for installing the unit to a wall, switch plate, or other surface.
4.3 Connecting LX-Bus and Keypad Bus Devices
Several factors determine the DMP LX-Bus™ and keypad bus performance characteristics: the wire length and gauge used,
thenumberofdevicesconnected,andthevoltageateachdevice.WhenplanninganLX-Bus™andkeypadbusinstallation,
keep in mind the following information:
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.
Whenusing18-gaugewiredonotexceed1,000feet.Toincreasethewirelengthortoadddevices,installan
additional power supply that is listed for Fire Protective Signaling, power limited, and regulated (12 Vdc nominal)
with battery backup.

mode.Refertothepanelinstallationguideforthespecicnumberofsupervisedkeypadsallowed.
3. Maximum distance for any one bus circuit (length of wire) is 2,500 feet 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. As
wire distance from the panel increases, DC voltage on the wire decreases. Maximum number of LX-Bus devices per
2,500feetcircuitis40.

You can connect devices (zone or output expansion modules) together on the same cable or provide separate runs back to
the card. The LX-Bus provides up to 100 zones or outputs.
Note: Do not use twisted pair or shielded wire when connecting an LX-Bus or keypad bus.
4.4 Wireless Keypad Association
EnableWirelessKeypadAssociationoperationonboththekeypadandpanel.
To enable association operation in the keypad, access the Installer Options Menu (3577
(INST)) and select RF Survey). The keypad logo LEDs turn on Red until association is
successful.
To enable association operation in the XR100 panel, reset panel 3 times within 12 seconds.
