Bosch B920 Wired LCD Security Keypad

Overview: The Bosch B920 is a wired security keypad featuring an alphanumeric LCD that displays words, numbers and symbols to communicate system status. If multiple events occur, the display cycles through them according to priority so the most important messages appear first. Keys and operation: The keypad provides 10 number keys, 7 function keys and 6 navigation keys. Pressing any key activates the keypad backlight and triggers the keypress tone (short beep). The function keys include programmable function keys plus dedicated one‑touch keys for arming and for bypassing zones. Audio and silencing: A built‑in speaker generates several distinct warning tones so users can identify event types by sound alone. The backlight also illuminates whenever an audible tone is produced. A user passcode can be entered to silence the audible alerts. Status indicators: Front-panel status indicators give a fast visual summary of the system’s condition for quick reference.
