Honeywell Home Intrusion LTEM-XA Lte-m Cellular Communicator

Product Description

The Honeywell Home Intrusion LTEM-XA is an LTE-M cellular alarm communicator designed for use on the AT&T network. It provides primary or backup communication paths for security alarm panels, transmitting alarm signals and system status over the LTE-M cellular network. The LTEM-XA is intended for installation by licensed security alarm technicians as part of residential or light commercial intrusion detection systems. LTE-M cellular communication delivers reliable, low-power connectivity suited to alarm signaling applications where a traditional phone line or broadband connection is unavailable or redundant.

The LTEM-XA is used in residential and light commercial security installations where cellular communication is required as a primary or secondary reporting path. It connects to a compatible alarm control panel and routes signals to a central monitoring station over the AT&T LTE-M network. Typical installations include retrofit upgrades replacing legacy POTS or older cellular communicators, as well as new construction where cellular-only communication is specified.

Key Features

• LTE-M cellular technology provides a dedicated, low-latency alarm communication path
• Operates on the AT&T LTE-M network for broad coverage across North America
• Designed for primary or supervised backup communication in alarm systems
• Sold as a single unit (each), suitable for one panel installation per communicator

Compatibility

Designed as an OEM-style cellular communicator for use with compatible Honeywell Home Intrusion alarm control panels that support LTE-M cellular communication modules. Refer to the panel installation guide to confirm communicator compatibility before installation.

Installation Notes

Installation must be performed by a licensed alarm systems technician in accordance with applicable local codes and the panel manufacturer’s instructions. Power down the alarm control panel and disconnect the backup battery before connecting or removing the communicator module. Verify AT&T LTE-M signal strength at the installation site prior to final commissioning. Do not install the communicator in a metal enclosure that blocks cellular signal without using an external antenna approved for this application.
