Orbis I.S. Multisensor detector

détecteur de chaleur sécurité intrinsèque Orbis I.S.

Orbis I.S.

Intrinsically safe multisensor detector

  • TimeSaver® Base
  • Patented FasTest® enabling functional testing in four seconds
  • DirtAlert® indicates limit of drift compensation
  • Tolerates extreme operating conditions: -40°C to +70 °C
  • False alarm reduction Flashing LED option
  • Warranty 10 years
Datasheet : Orbis I.S. multisensor detector (EN)

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.

Key Features :

  • Can be used for applications where smoke detectors are unsuitable
  • Ideal for environments that are dirty or smoky under normal conditions
  • Reduced incidences of false alarms
  • Increased reliability of detection

Environmental Characteristics

The environmental performance is similar to that of the Orbis I.S. optical smoke detector but it should be noted that heat detectors are designed to work at particular ambient temperatures. 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.
