Best For: Adding 4G cellular alarm communication to an existing compatible Bosch Solution 2000 or Solution 3000 system with a B450-M interface, or replacing an older communicator after an installer compatibility check.
Bosch B444-G Conettix Global LTE Cellular Communicator
The Bosch B444-G is a plug-in cellular module that carries compatible alarm-system communications over a mobile data network. It provides a practical communication path where a suitable fixed internet connection is unavailable, or where the system design requires cellular reporting.
For Solution 2000 and Solution 3000 installations, the B444-G connects through a separately supplied Bosch B450-M communicator interface. The panel, interface, firmware, SIM service and reporting destination must all be configured together.
Before ordering: This listing is for the B444-G cellular module. The B450-M interface and alarm panel are not included. Confirm your panel model, existing interface and firmware with CTC or your security installer before purchase.
Compatibility and Firmware
-
Solution 2000 / 3000: requires a compatible B450-M interface and supported panel and interface firmware.
-
Other Bosch systems: check the current manufacturer compatibility documentation for the exact panel and interface combination.
-
Existing 3G installations: an installer must assess the complete system before replacing a B443 or other older module; a modem swap alone may not complete the upgrade.
Install the appropriate current firmware before fitting the module. Firmware requirements can differ with hardware revision. Refer to Bosch Australia’s Solution 2000/3000 firmware guidance and the B444-G technical service note. Your installer should check for newer releases before performing an upgrade.
SIM, Mobile Coverage and App Setup
A suitable active SIM/data service, adequate mobile coverage and correct communication settings are required. The exact carrier, SIM arrangement and activation process must be confirmed for the Australian stock supplied. A SIM included in a manufacturer pack does not imply an activated service or included ongoing data.
RSC+ access on supported Solution systems requires compatible panel and B450-M firmware, the correct cloud/account configuration and testing. Installing this module does not automatically enable smartphone control. Monitoring-centre reporting also requires compatible receiver settings and a separately arranged monitoring service.
- Confirm the panel, B450-M, firmware and intended reporting or app service.
- Arrange the appropriate SIM/data service and check mobile reception at the property.
- Have the installer fit the module and supplied antennas, then configure the communication path.
- Configure supported app access or monitoring, and test alarm reporting, remote functions and fault notifications before handover.
Data, monitoring, activation and installation charges are excluded unless included in a separate written quote. This product page does not promise voice-call dialling or every notification feature on every panel.
Inclusions and Exclusions
-
Included: one Bosch B444-G cellular module with its supplied antenna accessories.
-
