Its purpose is to prevent the re-circulation of smoke from an area on fire to areas unaffected by the fire. It operates in air speeds of 0.5m/s to 20m/s and has a transparent cover to view detector head LED and an integral smoke test port.
Includes Series 65 mounting base & diode but NOT the detector.
