Bosch B444-V2 Conettix Verizon LTE Cellular Communicator

The Bosch B444-V2 is a CONETTIX plug-in 4G LTE cellular communicator designed for compatible Bosch intrusion and fire alarm control panels. Operating on the Verizon LTE Cat 1 network using bands B4 and B13, it provides secure two-way IP communication for central station alarm reporting, remote programming, and system monitoring. The module operates at 12 VDC nominal, drawing 35 mA in standby and 100 mA during alarm communication. It includes a Verizon SIM card, two magnetic-base antennas, and LED signal diagnostics, supporting primary, secondary, or sole-path cellular alarm communication in approved installations.

The Bosch B444-V2 CONETTIX Plug-In Cellular Communicator provides secure wireless alarm transmission and remote system connectivity for compatible Bosch intrusion and fire alarm control panels. Using the Verizon 4G LTE Cat 1 network on frequency bands B4 and B13, the module establishes two-way IP communication between supported Bosch control panels, central monitoring receivers, and remote management services. It supports central station alarm reporting, remote panel programming through Bosch Remote Programming Software (RPS), and compatible mobile applications, including Bosch Security Manager (BSM) and Remote Security Control (RSC). Its CONETTIX IP communication protocol incorporates 128-bit to 256-bit AES encryption with cipher block chaining, anti-replay and anti-substitution keys, and resistance to denial-of-service attacks. The B444-V2 supports commercial fire and burglary applications as a sole, primary, or secondary communication path when installed in an approved system according to applicable NFPA 72 requirements.

The B444-V2 operates at 12 VDC nominal and draws approximately 35 mA during standby operation and 100 mA during alarm communication. The compact module measures 2 inches high, 3.68 inches wide, and 0.60 inches deep (50 x 93.5 x 15.25 mm) and includes a Verizon 4FF SIM card and two magnetic-base omnidirectional antennas, each with a 3.3 ft (1.0 m) cable and SMA connector. Its dual SMA antenna connections support cellular communication, while integrated diagnostic LEDs indicate operating status and signal strength. A blue heartbeat LED displays module status, and red, yellow, and green indicators identify unacceptable, marginal, good, or very good cellular signal conditions. The communicator operates within a temperature range of 32 F to 120 F (0 C to 49 C) and supports 5% to 93% relative humidity, non-condensing. Classified for indoor Environmental Class III installations, the module can use optional Bosch B40-P, B40-MB25, or B40-MB50 antennas when additional antenna placement flexibility is required.

The Bosch B444-V2 supports direct installation in compatible B9512G, B8512G, B6512, B5512, B4512, and B3512 control panels, with firmware version 3.13 or higher required for the listed direct-connect configurations. The module also integrates with the B450 CONETTIX Plug-In Communicator Interface running firmware 3.13 or higher and the B465 CONETTIX Universal Dual Path Communicator running firmware 2.13 or higher. Installation uses a plug-in connector for power and panel communication, eliminating separate power and data wiring between the cellular module and its compatible host. The B450 connects to supported control panels through the system data bus, extending cellular communication options to additional Bosch configurations. Installers can configure supported communication settings using Bosch RPS and monitor cellular signal strength through compatible keypad diagnostics. Both antenna connections must be properly terminated, and cellular service requires an activated Verizon-compatible SIM and an appropriate Bosch Installer Services Portal account and data plan.

The B444-V2 cellular communicator supports alarm communication for offices, warehouses, retail facilities, educational buildings, healthcare properties, and commercial security installations requiring cellular connectivity. Its secure CONETTIX IP reporting and Bosch Remote Connect Programming Service compatibility allow installers to configure and maintain supported control panels remotely without requiring static IP addresses or manually configured router port forwarding. Compatible Bosch Security Manager integrations provide remote system status, control functions, alarm notifications, and push alerts, subject to panel capabilities and service configuration. The communicator carries manufacturer-documented regulatory approvals, including UL 864, UL 985, UL 1023, UL 1076, UL 1610, UL 1635, FCC Part 15 Class B, and California State Fire Marshal recognition for applicable system configurations. Before installation, integrators must verify control panel firmware, available Verizon LTE coverage, cellular service activation, receiver compatibility, and applicable fire or burglary communication requirements.
