Esser 803374.EX.IN FM Approved IQ8Quad O²T Ex Multi-Sensor Detector, Non-Isolated
Product Code: 803374.EX.IN
An intelligent detector that evaluates two optical smoke sensors with different scattering angles together with a heat sensor. It compares sensor signals and classifies smoke; it reduces false alarms arising from vapor or dust. It can distinguish test fires TF1 and TF6 defined in standards and operates at high ambient temperatures up to +65 °C. The non-isolated version is used in Ex areas via barrier 804744 or 764744.
