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

Product code:58000-700APO


Main features and benefits:

  • 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
