263CSMX CDMA Cellular Communicator

Description

The 263CSMX CDMA Cellular Communicator provides a fully supervised alarm communication path over the CDMA network. The 

263CSMX 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 263CSMX 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 panels.

Note:

 The ACTIVATE CELL prompt will only display if a CDMA modem is installed. To perform the cellular activation 

process from a keypad, the panel must be in contact with a Verizon owned tower.

What is Included

The 263CSMX/381-2 includes the following:

• One Model 263CSMX
• One Model 383 Rubber Duck Antenna
• One PCB Standoff
• One 381-2 Antenna Cable

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 263CSMX

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 263CSMX.
3. Press the 263CSMX 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.

For XT30/XT50 see Figure 1.

For XR150/XR350/XR550 See Figure 2.

Note:

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

allow placement of the cell module.

Connecting the Antenna

All Panels:

1. Attach the 381-2 cable to the SMA connector.

2. Position one of the 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 263CSMX. See Figure 3.

Note:

 As an alternative, an antenna coax can be connected 

directly to the 263CSMX SMA connector when the coax enters the enclosure via 

conduit.

Automatic Cellular Activation (XR150/XR350/XR550 Series and XT30/

XT50 Series panels)

Automatic Cellular Activation is available for the 263CSMX CDMA Cellular Communicator 

on XR150/XR350/XR550 Series (Version 109 or higher) and XT30/XT50 Series (Version 

122 or higher) control panels. If the 263CSMX Cellular Communicator has not been 

previously activated, Automatic Cellular Activation occurs when the panel powers up 
or is reset. 

ACTIVATE CELL

 is only necessary when Automatic Cellular Activation is not 

successful and communication was not established. To perform the cellular activation 

process from a keypad, the panel must be in contact with a Verizon owned tower.
