Case Studies

In the event of fire, the fire detection time is most critical. An efficient & timely detection would improve on response and timely control of situation.

The Different technologies compared included Aspiration Smoke Detection and spot-type (point) and beam detectors.

How Shrack Seconet ASD works

Aspiration system is positioned where smoke will travel, for very early detection and investigation.

Sampling pipe is positioned on roof top , within the storage racking with sampling points located along the pipe work.

ASD works by continuously drawing air into a distributed pipe network via a high-efficiency aspirator. The air sample then passes through a dual-stage filter. The first stage removes dust and dirt from the air sample before it enters the laser detection chamber.

The second, ultra-fine stage provides an additional clean-air supply to keep the detector’s optical surfaces free from contamination, ensuring stable calibration and long detector life as well as minimizing nuisance alarms.

From the filter, the air sample goes through the calibrated detection chamber where it is exposed to a laser light source. When smoke is present, light is scattered within the detection chamber and is instantly identified by the highly sensitive receiver system.
