High Sensitivity Smoke Detection (HSSD) is the most sensitive form of smoke detection available.
High Sensitivity Smoke Detection systems comprise an air sampling unit (ASU) from which red air sampling pipework is routed throughout the protected area.
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.
