The NAPCO sle-max2-fire is a universal, panel-powered cellular communicator designed for commercial fire alarm control unit (FACU) applications. It operates on both AT&T and Verizon networks simultaneously using a dual SIM architecture, eliminating single-carrier dependency in mission-critical fire notification systems. The unit supports dual communication paths, either cell-to-cell or cell-to-IP, all within a single module. Licensed fire alarm technicians and low-voltage contractors install this device to meet redundant signaling requirements common in commercial fire system upgrades and new construction.
This communicator is suited for commercial settings where fire alarm panels require reliable, carrier-diverse supervision and alarm reporting. The panel-powered design simplifies installation by drawing power directly from the FACU, removing the need for a separate power supply. It fits into retrofit and new-installation scenarios where a single, compact module must handle both primary and backup communication paths without additional hardware.
Designed as an OEM-style replacement and upgrade communicator for commercial fire alarm control units requiring dual-path cellular reporting.
Installation should be performed by a licensed fire alarm technician in accordance with NFPA 72 and local authority having jurisdiction (AHJ) requirements. Power down the fire alarm control panel before wiring the communicator module to avoid damage to panel circuitry. Verify carrier signal strength at the installation site for both AT&T and Verizon networks prior to final commissioning. Do not substitute SIM cards or alter the dual-path configuration without confirming compliance with the monitored account and central station requirements.
