VESDA Air Sampling Smoke Detection systems it consists of a central detection unit which draws air through a network of pipes to detect smoke. The sampling chamber is based on a nephelometer that detects the presence of smoke particles suspended in air by detecting the light scattered by them in the chamber.
Vesda provide one of the most effective levels of fire protection available. They detect smoke much earlier than other devices. Managing your fire risk VESDA detection systems are usually installed in areas where fire could result in serious, perhaps catastrophic, business disruption.
