Overview
DMP LTE cellular communicator (263LTE, 265LTE, FirstNet SKUs) — cellular alarm reporting path for XR/XT panels.
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.
