General Information
The LTE-X Series Communicator, herein referred to as the communicator, easily connects to your security system’s control panel and sends alarms and messages to AlarmNet for subsequent transfer to the central monitoring station. It can be mounted directly on the control panel or remotely.
The LTE-X Series includes the following models:
- LTE-XV (US, Verizon network)
- LTE-XA (US, AT&T network)
- LTE-XC (Canada)
The LTE-X communicates with AlarmNet over the LTE network. If a data connection cannot be established, it will attempt to send a transmission via SMS.
In addition to alarm reporting, the communicator provides upload/downloading capability of Honeywell’s control panel data over the Internet using LTE technology.
Features
- Reports fire, burg, and status message.
- Internal MIMO antennas provide additional security.
- Simple programming using the 7720P programming tool or via the AlarmNet 360 website.
- Uses 2 way ECP communication with the control panel.
- Sends reports in Contact ID format.
- Supports remote control of alarm system via Remote Services feature.
- Allows uploading and downloading of control panel data.
- Fully powered (primary and backup battery) from the control panel.
- The LTE-X is for control panels that support ECP communication.
Specifications

Data Encryption
The communicator uses 256 bit AES (Rijndael) encryption (which is required for certain government installations). The AlarmNet-i AES Encryption Software Module Version 1.0 contained in the Honeywell products has NIST approval. Listings for this approval can be found at https://csrc.nist.gov/Projects/Cryptographic-Algorithm-Validation- Program/Validation/Validation-List/AES and search for “Certificate number 979.
Remote Services Features
Resideo offers secure web based services that enable users to remotely monitor and control their security system. These web services enable users to:
- Monitor and control their security system from a website
- Receive e-mail and text message notifications of system events
- Control the system and receive confirmations using text messages
- Monitor and control IP video cameras
Dealers can enroll their customers for “Remote Services” by using the AlarmNet 360 website. Once enabled, the specific programming fields associated with these features can be programmed into the communications device either remotely using the AlarmNet 360 website or locally using the 7720P programming tool.
Testing the System
After installation the security system should be tested. Refer to the control panel installation instructions for procedures to test the entire system
Compatibility
The communicator functions with any control panel that utilizes a Resideo ECP bus and supports a communicator.
Compliance
This device has been tested by ETL to meet the following standards:
- UL985 – Residential Fire
- UL1023 – Residential Burg
Mount and Wire the Module – Select a Mounting Location
When choosing a suitable mounting location, understand that it must be mounted indoors, and for best signal strength it should be mounted vertically. Signal strength is very important for proper operation. For most installations, mounting the unit on the control panel provides adequate signal strength and we suggest that this method is tried first. Especially if the control panel is not in a basement location or in an area that contains large metal objects
If the control panel location does not provide adequate signal strength, then the communicator can be mounted remotely.
Verify Satisfactory Signal Strength
This procedure checks for satisfactory signal strength at the communicator. You can temporarily power the communicator from a 12V battery or from the control panel’s AUX PWR terminals. In buildings where reception may be a problem, powering from a battery would allow the communicator to be portable. The following procedure assumes the control panel will be used for power. (If satisfactory signal strength is present at the control panel that is the preferred mounting location.)
- Ensure power to the control panel (both AC and battery) is off. Open the enclosure and connect the ECP cable connector to the communicator. Connect the cable wires to the control’s ECP terminals.
- Turn power on and wait for the communicator to initialize*. Position the communicator near a suitable mounting position. Verify the SIGNAL LED (green) lights steady. This indicates satisfactory signal strength

3. Verify the SIGNAL LED (green) remains steady for a few minutes, then mark that mounting position. Turn power off.
Mounting the Module on the Control Panel
- Ensure power to the control panel (both AC and battery) is off, then remove the knockout on the top right of the control panel cabinet.
- Open the communicator cover. Remove the Hole Cap attached to the plastic (trim as necessary), and snap it into the top opening of the enclosure.
- Remove the bottom knockout on the enclosure for the threaded mount. Then install the threaded mount so it snaps into the plastic retaining tabs. Mount the communicator assembly on the cabinet’s knockout, and fasten with the locking nut.

- Connect the ECP cable to the communicator circuit board and thread the wires through the threaded mounting adapter.
- Refer to the control panel’s installation guide, and complete the ECP cable wiring.
- Secure the wiring with ties as necessary.
Mounting the Module on the Wall
- Ensure control panel power (both AC and battery) is off, then remove a suitable knockout on the top or side of the control panel cabinet.
NOTES: If in the wall wiring will be used, route the wiring through the communicator’s rear wiring access hole. - If surface mounted wiring will be used, remove the communicator’s bottom knockout and use that to route the wiring.
- Open the communicator’s cover. Remove the Hole Cap attached to the plastic (trim as necessary), and snap it into the top opening of the enclosure.
- Secure the enclosure to the wall using both mounting holes.

Connect the ECP cable to the communicator circuit board. When mounting the communicator off the cabinet, the length of the supplied ECP cable will have to be spliced to a four-wire extender cable. Ensure the splices are located within the communicator’s enclosure.
Use the table below to determine the minimum wire gauge for the extender cable.

- Route the wires through the rear wiring access hole or bottom knockout on the communicator. Continue routing the wiring to the control panel. A control panel knockout that is presently used can be utilized, however DO NOT utilize a control panel knockout that is being used for primary power.
- Refer to the installation guide for the control panel and complete the ECP cable wiring
- Secure the wiring with ties as necessary.
Programming the Module
You can program the communicator by one of the following methods:
- Using the AlarmNet 360 website.
- Using the 7720P Programming Tool.
- Using the control panel’s programming mode (for panels that support this option) to access the communicator’s programming.
