Busch-Jaeger Busch-Rauchalarm 6833/01-84 Photo-Optical Smoke Alarm

The Busch-Jaeger Busch-Rauchalarm 6833/01-84 (ProfessionalLINE) is a photo-optical smoke detector that uses the Tyndall light-scattering principle to detect smouldering and open indoor fires. It is powered by a built-in 3 V lithium battery rated for a minimum 10-year service life, sounds an 85 dBA alarm at 3 m, and is certified to DIN EN 14604 with VdS and >Q< approval. Up to 20 detectors can be interlinked either over a 2-wire line or via the optional Busch-Rauchalarm RF radio module, which also allows connection to a Busch-free@home system through the Alarm-Stick.
