19.1 J24 Header

The J24 header is located to the right of the J7 Expansion Module on the right side of the circuit board and is used

to connect the DMP Model 263C CDMA or 263H HSPA+ Cellular Communicators. This provides a fully supervised alarm

communication path for the XR150/XR350/XR550 panel. Refer to the 263C (LT-1264), or 263H (LT-1270) Installation

Sheet for complete information.

19.2 Module Installation

1. Insert the PCB standoff end with anges into the standoff hole in the panel PCB.

2. Align the PCB standoff with the standoff hole in the module PCB.

3. Press the module PCB card 12 pin connector onto the Cell Module (J24) connector on the panel while applying

even pressure to both sides of the board to fully seat the module. See Figure 13.

Note: If needed, the PCB can be removed from the enclosure to allow placement of the cell module.

19.3 Connecting the Antenna

1. Attach a 381 cable to the SMA connector on the cell

module.

2. Position one of the supplied washers onto the other end

of the 381 SMA connector and push the threaded end

through an enclosure knockout.

3. Position the second washer onto the threaded end

extending through the knockout and secure the nut.

4. Attach the included 383 Antenna to the SMA connector.

See Figure 13.

Note: As an alternative, an antenna coax can be connected

directly to the cell module SMA connector when the

coax enters the enclosure via conduit.
