Apollo Fire Detectors | Discovery Marine Multi-Sensor Detector (Optical/Heat) [SIL2]

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

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
