Bosch B942 Color Graphic Touch Screen Keypad, Black

The Bosch B942 is a black color-graphic touchscreen security keypad with an integrated proximity reader, designed for compatible Bosch B Series, G Series, and GV4 intrusion alarm control panels. Featuring a 125 kHz RFID credential reader, automatic presence-activated display, four supervised inputs, and one normally open relay output, it supports convenient system arming, disarming, and alarm monitoring. Operating on 12VDC nominal power through the four-wire SDI2 bus, the keypad provides adjustable screen brightness, audible event notifications, multilingual menus, and optional card-based authentication for residential and commercial security systems.

Bosch B942 Color Touchscreen Security Keypad with Proximity Reader

The Bosch B942 Color Graphic Touchscreen Keypad provides an interactive security system interface for compatible Bosch B Series, G Series, and GV4 intrusion alarm control panels. Featuring a slim black enclosure and illuminated touchscreen, the keypad allows authorized users to arm and disarm protected areas, review alarm conditions, acknowledge system messages, and access programmed security functions. Its graphical user interface combines icons, text, numeric keys, and contextual menus to simplify navigation through system commands and operating information. A built-in presence detector automatically activates the display when a person approaches, while adjustable brightness and audible volume settings allow the interface to be tailored to the installation environment. The B942 is suitable for residential properties, commercial offices, institutional buildings, and security systems requiring centralized or multi-area control.

The B942 incorporates a 125 kHz proximity credential reader compatible with EM4102 RFID technology, allowing authorized users to substitute a supported credential for conventional keypad passcode entry. Compatible credentials include the Bosch ACA-ATR13RFID proximity token and ACD-ATR11ISO-RFID card. The reader also supports credential-based dual authentication when configured through a compatible control panel, providing an additional authentication method for protected locations. A built-in speaker generates distinct audible tones for alarms, system troubles, and other programmed events, while dedicated status indicators identify ready, armed, trouble, gas alarm, and power conditions. The keypad displays messages from multiple security areas according to its programmed authority and system configuration. Its multilingual user interface supports 12 languages, including English, Spanish, French, German, Portuguese, Italian, Dutch, Polish, Greek, Hungarian, Swedish, and Chinese.

The Bosch B942 communicates through a four-wire SDI2 data bus that supplies both operating power and communication with the connected alarm control panel. The keypad operates on 12VDC nominal power and draws approximately 200mA in standby or 300mA during alarm operation when the proximity reader is disabled. With the proximity reader enabled, current consumption increases to approximately 300mA in standby and 400mA during alarm operation. Four integrated 1k-ohm supervised input circuits allow compatible detection devices to be connected directly to the keypad, reducing the need for separate input expansion modules in certain installations. A built-in normally open relay output rated at 1A at 24VDC provides an additional programmable switching interface for compatible low-voltage control applications. The keypad supports 18-22 AWG wiring, and multiple compatible keypads can share the control panel's SDI2 communication bus within the manufacturer's wiring and system capacity limitations.

The Bosch B942 measures approximately 6.2 inches wide, 4.7 inches high, and 0.65 inches deep, with a lightweight housing constructed from ABS and PMMA materials. Its black architectural design supports installation in residential entryways, commercial lobbies, security offices, and other supervised indoor locations. The keypad includes mounting hardware and mounting plates for concealed wiring or surface wiring configurations. For installations on concrete or block walls, the optional Bosch B56 surface mounting box provides additional mounting flexibility, while the B96 trim plate helps conceal wall markings left by previously installed keypads. The device operates within a temperature range of 32 F to 122 F (0 C to 50 C) and supports relative humidity from 5% to 93% non-condensing under the manufacturer's specified conditions. Its surface-mount configuration allows installers to position the keypad near protected entrances or other convenient system control locations.

The Bosch B942 is compatible with supported B9512G, B8512G, B6512, B5512, B4512, B3512, and D9412GV4/D7412GV4 control panel configurations, subject to the applicable firmware requirements. Beyond routine system operation, the keypad supports installer programming, diagnostics, and troubleshooting through the associated control panel, while Bosch Remote Programming Software provides additional system configuration capabilities. Manufacturer documentation identifies applicable UL 985, UL 1023, UL 1076, UL 1610, and related intrusion and fire system standards, with approved applications dependent on the complete installed alarm system. By combining touchscreen operation, proximity credential authentication, supervised input expansion, programmable relay control, and SDI2 connectivity, the Bosch B942 provides a flexible user interface for professionally installed security and compatible life safety monitoring systems.
