The Orbis Intrinsically Safe (I.S.) Optical/Heat Multisensor Detector is recognised as a good detector for general use but is additionally more sensitive to fast burning, flaming fires – including liquid fires – than optical detectors.

Orbis I.S. Optical/Heat Multisensor Detectors can be readily used instead of optical detectors but should be used as the detector of choice for areas where the fire risk is likely to include heat at an early stage in the development of the fire.

The Multisensor detector has two sensors, one for smoke and one for heat with the alarm decision derived from either sensor or combination of both.

As with all the Orbis I.S. range of detectors the increased reliabilityof detection is combined with high immunity to false alarms.
