The Apollo Orbis ORB-OP-52027-APO is an intrinsically safe optical smoke detector. The Apollo ORB-OP-52027-APO works using the light scatter principle, and is ideal for applications where slow-burning or smouldering fires may occur.
The optical design of the Orbis ORB-OP-52027-APO allows it to respond to a wide spectrum of fires. The sensing chamber of the Orbis ORB-OP-52027-APO contains an optical sensor which measures back-scattered light. The sensitivity to black smoke is greatly improved, and the sensing chamber has been to keep out dust and other airborne contaminants.
The ORB-OP-52027-APO Orbis I.S. Optical smoke 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.
