263H HSPA+ Cellular Communicator

Description

The 263H HSPA+ Cellular Communicator provides a fully supervised alarm communication path over the HSPA+ network. The 263H 

is installed in the panel enclosure and powered by the panel, so no additional enclosure, power supply or battery back-up is 

needed.

Compatibility

The 263H is compatible with XT30/XT50 Series panels (Version 112 or higher) that do not contain a built-in cellular modem and 

XR150/XR350/XR550 Series control panels.

What is Included

The 263H includes the following:

• One Model 263H

• One SIM Card

• One Model 383 Rubber Duck Antenna

• One PCB standoff

Programming/Activation

Cellular Service is required before using the 263H for signal transmission. In Remote Link panel communication programming, 

select Cellular as one of the Communication types. The 263H comes with a SIM card ready for activation with SecureCom 

Wireless, LLC. More information is available at www.securecomwireless.com or refer to the Remote Link Users Guide (LT-0565) 

or, use a SIM card provided by the carrier of your choice. If you are activating the unit with an alternate carrier, program the APN 

provided by your carrier during panel programming.

Installation Safety

Ground Yourself Before Handling the Panel!

 To discharge static, touch any grounded metal, such as the enclosure, before 

touching the panel.

Remove All Power From the Panel! 

Remove all AC and Battery power from the 

panel before installing or connecting any modules, cards, or wires to the panel.

Installing the SIM Card

Insert the SIM 

card into the 263H as pictured in Figure 1.

Installing the 263H

For XT Series:

1. Insert the PCB standoff end with flanges into the standoff hole in the panel PCB.
2. Hold the 263H at an angle and align the SMA antenna connector with the antenna 

hole in the top of the panel enclosure.

3. Align the PCB standoff with the standoff hole in the 263H.

4. Press the 263H 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 2.

For XR150/XR350/XR550 Series:

1. Insert the PCB standoff end with flanges into the 

standoff hole in the panel PCB.

2. Align the PCB standoff with the standoff hole in 

the 263H.

3. Press the 263H 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 3.

Note:

 If needed, the PCB can be removed from the enclosure to allow 

placement of the cell module.

Connecting the Antenna

For XT Series:

Attach the included antenna to the SMA connector. See Accessories for 

additional antenna options. Refer to Figure 2.

For XR150/XR350/XR550 Series:

1. Attach the 381-2 cable to the SMA connector.
2.  Position one of the supplied washers onto the 381-2 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 3.
5. Attach the opposite end of the 381-2 Coax to the SMA connector on 

the 263H. See Figure 3.

Note:

 As an alternative, an antenna coax can be connected directly to the 263H SMA connector when

 

the coax enters the enclosure via conduit.
