Honeywell Home Videofied® XTO640 Wireless Outdoor Alarm Panel with ANXTSIM LTE Sim Card Installation Notes

AlarmNet LTE communicator — cellular module for Total Connect 2.0 and central station reporting (LTE-X/C/V, LTEM-XT, LyricLTE, ProSeries LTE, etc.).

Without reliable cellular reporting, remote arm/disarm and central station signals stop when phone lines or broadband fail. Match the exact module SKU to your panel model and dealer platform before truck roll.
