Conventional Beam Detectors
– OSI-RE-SS
The OSI-RE-SS is a 4-wire, single-ended, reflected type beam smoke detector that includes an 8″ reflector and an integral sensitivity test.
The OSI-RE-SS is a reflector- type linear optical beam smoke detector designed to operate as a component of fire alarm systems. The beam operates primarily on the principle of light obscuration utilising an Infra-Red beam. Optical beam smoke detectors are particularly appropriate for protecting buildings with large open spaces such as warehouses, atriums etc.
The OSI-RE-SS detector is a combined transmitter/receiver unit that can be directly connected to a conventional detector circuit.
