Overview
The Radionics D8112 fire alarm control panel is a legacy security system from Bosch designed to manage fire alarm and burglary detection across multiple zones. The D8112 model is out of production, making it valuable for replacement installations on existing systems. The CCDS3-02966-004 assembly variant includes the main control board without front cover, making it suitable for custom enclosure integration or as a spare component. This unit operates on standard DC backup power architecture typical of Bosch alarm panels from the 1990s–2000s era.
