Ademco/Honeywell Security 4297

The Honeywell 4297 is a V-Plex polling loop isolation and extension module for Ademco fire alarm control panels that expands addressable device capacity by receiving control panel input signals and retransmitting boosted copies via an isolated extension loop. The module provides full loop supervision with automatic fault reporting, extending total system wiring capability from approximately 4,000 feet to 8,000 feet without requiring additional control panel hardware.
