High Sensitivity Smoke Detection (HSSD) is an aspirating system; mainly used in Computer Rooms it samples air from the room through a series of points in the room. Usually sampling in 3 areas, the room void, the underfloor void and the above-ceiling void.

Analogue Addressable Detection is an easy way to cover large spaces, each detector is given a number and a piece of location text. This text allows the facilities team/security to view the detector and see quickly where the problem lies.
