Discovery Marine Multi-Sensor Detector (Optical/Heat) [SIL2]

Name: Discovery Marine Multi-Sensor Detector (Optical/Heat) [SIL2]
Brand: Discovery
SKU: 58000-700MAR

58000-700MAR

The Discovery Marine 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
Certified to a broad range of marine approvals and EAC approved
Assessed and certified for use in a safety function to SIL level 2
