The Apollo Orbis Marine ORB-OH-43001-MAR is an Optical Smoke/Heat Multisensor Detector that is suited for general use, but is more sensitive to fast burning, flaming and liquid fires than optical detectors.
The Apollo ORB-OH-43001-MAR can be used instead of an optical detector, but should be used as the detector of choice where the fire risk is likely to include heat at an early stage in the development of the fire.
The ORB-OH-43001-MAR has 2 sensors, one for smoke and one for heat, with the alarm decision derived from either sensor, or from a combination of both.
The ORB-OH-43001-MAR Orbis Marine Multisensor Detector is suitable mounting on base ORB-MB-00001-MAR. For higher water ingress protection, the 45681-217APO Deckhead Mounting Box can be used.
