The AirSense Stratos HSSD2 (9-30621) is a large-area, high-sensitivity aspirating smoke detector (ASD) designed to give the very earliest warning of incipient fire with a minimum rate of nuisance alarms. It takes up to four sampling pipes with up to 200 m of combined pipe and covers areas of up to 2000 m².
ClassiFire artificial intelligence automatically sets the detector to the best sensitivity for the protected area, from high sensitivity in a computer room to reduced sensitivity in a smoky area. It has an LCD and keypad, five relay outputs and RS-485 SenseNET networking. Typical applications include data storage, computer rooms, equipment racks, plant and motor rooms, air-conditioning units, prison cells and heritage properties.
