Discovery Multi-Sensor Detector (Optical/Heat)

Name: Discovery Multi-Sensor Detector (Optical/Heat)
Brand: Discovery
SKU: 58000-700APO

58000-700APO

The Discovery Multi-Sensor Detector consists of optical smoke and thermistor temperature sensors which give a combined signal for improved false alarm management.

Reliable fire detection in areas with a very wide temperature range from -40°C to +70°C
Five operating modes for customised fire detection and enhanced false alarm management
Drift compensation to ensure constant sensitivity
A great alternative to Ionisation detectors
