58000-600APO

The Discovery Optical Smoke Detector are high-specification devices using the light scatter principle to quickly detect fire while effectively managing false alarms.

Reliable fire detection in areas with a very wide temperature range from -40°C to +70°C
Five operating modes suitable for a range of applications where unique response behaviour is required
Drift compensation to ensure constant sensitivity
Ideal for accommodation decks, passages and escape routes
