Product Overview

AVENAR detector 4000 is Bosch's family of addressable automatic fire detectors for LSN loops, covering heat, optical, dual-optical and multi-sensor variants, including models with chemical and CO sensing. The -R variants have rotary switches for manual or automatic addressing, and most variants include short-circuit isolators. Each detector has a 360° alarm LED and self-monitoring of its sensors.
