The Orbis IS Multisensor Smoke Detector benefits from the same false alarm technology as the Optical Smoke Detector with the addition of a heat sensing element.

The environmental performance of the multisensor detector is the same as that of the Orbis IS optical smoke detector. Also classification and BASEEFA Certificate Number are the same as for the optical smoke detector. Operating and storage temperature: –40°C to +70°C Operating temperature is restricted by the intrinsic safety gas classification. Class T5: –40°C to +45°C Class T4: –40°C to +60°C The detector must be protected from conditions of condensation or icing.

Key Features

• Reduces false alarms
• Sensitive to fast burning, flaming fires
• Improved sensitivity to black smoke
• Compensation for slow changes in sensitivity
