Two-line SDI2 alphanumeric keypad

The BOSCH B920 provides a two-line alphanumeric display for security system interaction. It connects via the SDI2 bus and suits installers fitting commercial or residential access control panels. Users adjust volume and brightness locally for comfortable operation. The keypad presents system messages for all configured areas.

Adjustable volume and brightness

Each unit lets the operator set audio level and screen intensity to match the installation environment. Normal use draws minimal power from the SDI2 bus without generating noticeable heat or noise. No active cooling is required, keeping operation silent in offices or hallways. The simple interface reduces configuration time for technicians.

Questions about this item

How is the B920 keypad connected to the control panel, and what wiring step is often missed?

The B920 connects via the SDI2 bus using a four-wire run; the step often missed is setting the correct device address at the keypad so the panel recognises it on the bus.

What maintenance will the B920 keypad need over time?

Clean the display and keys with a soft, dry cloth; if brightness fades or keys become unresponsive after extended use, the unit is replaced as a single SDI2 bus device.
