Bosch B926F

The Bosch B926F is a fully supervised fire annunciator keypad with a two-line LCD display for fire alarm system status monitoring and control in commercial and institutional facilities. Designed for integration with Bosch BG Series control panels via SDI2 network interface, this fire keypad provides dedicated function keys for critical operations—ACK (acknowledge), SILENCE, RESET, and DRILL—while displaying up to 32-character point, user, and area names.
