Discovery Multi-Sensor Detector (CO/Heat)

58000-305APO

The Discovery Multi-Sensor Detector contains a CO detection cell and a thermistor temperature sensor whose outputs are combined to give the final analogue value.

  • Responds to smouldering and flaming fires
  • Less susceptible to false alarms caused by steam and dust
  • Five response modes
  • Remote test feature
