1 | Overview
The B442 provides IP communication over the GSM (GPRS)
digital cellular network by directly connecting the module to the
control panel. The control panel can be confi gured to use B442
for alarm reporting, remote access and personal notifi cation
The B442 module requires a SIM card with active cellular
service to communicate. Bosch Cellular service and SIM
cards are available in some countries. Consult your Bosch
representative for details.

3 | Diagnostic LED descriptions
At power up, all module LEDs activate for several seconds,
indicating proper insertion. The Signal LEDs then turn off until
the module registers on the cellular network. Registering a new
module might take up to 2 minutes.
Check the LED display to ensure a good signal strength level,
and adjust the antenna location as required. The signal strength
LEDs momentarily turn off to indicate the module has measured
and updated the signal strength status. Refer to Table 3.1.

4 | Confi guration
The programming of B442 Plug-in Communicators is done
through the compatible control panel or the B450 Plug-in Com-
municator Interface. Refer to your control panel guide, remote
programming software help, or the B450 IOG for parameter
descriptions, options and defaults. For Bosch Cellular account
status and management, use RPS or the online service portal
(go to and click on
the Cellular Portal Login link).
Confi gure network alarm communication routes and settings
in the control panel. Cellular carrier-specifi c settings (such
as Access Point Name and SIM card security) can also be
programmed through the control panel or Conettix Plug-in
Communicator Interface (B450).
