Honeywell LTE-L57V LYNX LTE Communicator for Verizon

Honeywell LTE-L57V Verizon LTE Communicator for LYNX Touch

Overview

The Honeywell LTE-L57V is an internal cellular communicator module that adds Verizon 4G LTE connectivity to LYNX Touch alarm panels. It is the Verizon counterpart to the LTE-L57A, installing inside the panel via a bridge connector board. The module supports LTE bands 12, 13, 5, 4, and 2 with 256-bit AES encryption.

Deployment scenarios

The LTE-L57V is specified for residential LYNX Touch installations in areas where Verizon provides better LTE coverage than AT&T, or where the monitoring company operates on the Verizon network. It replaces sunset 3G and CDMA modules in L5200, L5210, and L7000 panels with firmware 9.00.201 or newer.

Communication specifications

Operates on Verizon 4G LTE across bands 12, 13, 5, 4, and 2. 256-bit AES encryption. Full Contact ID reporting. Internal antenna. Standby current is 30 mA with a maximum transmit current of 490 mA.

Installation notes

Marty Allison

The LTE-L57V is the Verizon variant of the LYNX Touch communicator module. In my experience, the choice between the L57A and L57V comes down entirely to which carrier has better signal strength at the specific panel location. There is no functional difference between the two beyond the cellular network.

Technical Highlights:

• Verizon LTE coverage: Provides cellular communication on the Verizon network for locations where AT&T is weak
• Internal module format: Installs inside the LYNX panel enclosure without external hardware

Deployment Considerations:

• Check Verizon coverage maps and run a signal test at the panel location during the site survey
• Ensure the LYNX Touch panel firmware is at or above version 9.00.201 before installation

Order the correct variant based on your site survey results. Swapping between AT&T and Verizon modules after installation requires a new cellular account activation, so getting the carrier selection right the first time saves a return trip.
