Discovery Marine Addressable Ionisation Smoke Detector

Discovery Ionisation Smoke Detector

The Discovery Marine Ionisation Smoke Detector uses a low activity radioactive foil to detect fires by irradiating the air in the smoke chambers causing a current flow. If smoke enters the chamber, the current flow is reduced leading to an alarm. The detector has a choice of five operating modes which are selected at the fire control panel.

  • Responds well to fast-burning, flaming fires.
  • Designed to operate in a variety of environments.
  • Resilient to dust.
  • Five EN54 approved response modes.
  • Remote test feature.
