Bosch B465-MR-120WI

The Bosch B465-MR-120WI is a universal dual-path communicator kit that upgrades legacy PSTN digital dialers to modern IP-based central station reporting, supporting seamless transmission over Ethernet with optional cellular backup through Conettix plug-in modules. This communicator automatically detects and converts Contact ID, SIA, Pulse 3/1, and Pulse 4/2 signals without requiring control panel reprogramming, making it compatible with virtually any fire alarm control panel in service. The integrated 16.5 VAC 40 VA transformer provides stable power for system components, while support for either 7 Ah or 18 Ah backup batteries ensures continuous operation during power loss—critical for maintaining central station communication during emergencies.
