High Sensitivity Smoke Detection (HSSD) is the most sensitive form of smoke detection on the market. It is designed to give very early indication of an emerging fire condition. This pre-emptive warning provides the time necessary to take corrective action and avoid the danger that a fire can cause. HSSD may sometimes be referred to as an ‘Aspirating System’,
Benefits of HSSD:
HSSD systems comprise an Air Sampling Unit (ASU) from which air sampling pipework is routed throughout the protected area. This area can be as large as 2000 square metres.
Air is continuously drawn via apertures in the pipework to the ASU which uses laser technology to analyse the air quality. At commissioning stage, the programmable threshold levels are set giving the facility for a pre-alarm warning at a first threshold and full alarm at a second threshold.
Applications for HSSD include very high bay warehousing, environments which are subject to extremes of temperature, e.g. cold stores, and areas with rapid air movement such as air conditioning plenum chambers.
