Discovery Ionisation Smoke Detector (58000-500)

The Discovery Ionisation Smoke Detector (58000-500) irradiates air to produce ions that travel to the positive and negative electrodes, creating a current flow. As smoke enters the outer chamber, the flow drops and voltage increases. The voltage is measured and an analogue signal is converted to digital for transmission to the control equipment.

Discovery Ionisation Smoke Detector

An intergrating ionisation detector, suitable for use in areas where transient high levels of smoke may be expected, is also available
