Very Early Smoke Detection and Alarm VESDA

Very Early Smoke Detection and Alarm (VESDA)... 

High sensitivity sampling smoke detection systems provide the best form of rapid smoke detection for Ir hly critical equipment or in high air flow situations. The Very Early Smoke Detection and Alarm (VESDA) system is basically a suction pump with collection tubes or pipes that use an optical smoke detection device test for evidence of smoke particles. Since it gathers air samples from the protected area, it is much faster in detection than ordinary detection devices that have to wait for the smoke to arrive to it. VESDA systems may be subject to some dilution effect to the sampling mechanism since the tubes may collect air samples from several sampling ports. This may reduce its response time.
