The Apollo Orbis I.S. ORB-OH-53027-APO is an intrinsically safe multisensor detector that benefits from the same false alarm technology as the Apollo Orbis Optical Smoke Detector, with addition of a heat sensing element. The Apollo Orbis I.S. ORB-OH-53027-APO is used in areas where the fire risk is likely to include heat at an early stage in the development of the fire.
The ORB-OH-53027-APO has two sensors, one for smoke and one for heat. The alarm decision is derived from either sensor, or a combination of both.
The ORB-OH-53027-APO Orbis I.S. Multisensor detector is suitable for mounting on ORB-MB-50018-APO Orbis I.S. TimeSaver base. For higher water ingress protection, the 45681-217APO Deckhead Mounting Box can be used.
