Bosch B465

The Bosch B465 is a universal dual-path communicator module that enables fire and intrusion alarm panels (both Bosch and third-party compatible systems) to transmit alarm signals to central monitoring stations via simultaneous IP and optional cellular communication paths. This redundant communication architecture ensures continuous central station connectivity even if one transmission path becomes unavailable, meeting stringent fire code requirements for supervised alarm reporting. The module supports Contact ID, SIA, Pulse 3/1, Pulse 4/2, Modem II, IIe, and IIIa2 formats with automatic format detection and field-selectable 16.5 VAC or 24 VDC power, while AES 256-bit encryption protects all transmitted alarm data from interception.
