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.
