VESDA – Very Early Smoke Detection & Aspiration
An aspirating smoke detector also known as Very Early Smoke Detection Aspiration 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. ASDs can typically detect smoke before it is visible to the naked eye.
In most cases aspirating smoke detectors require a fan unit to draw in a sample of air from the protected area through its network of pipe.
They are excellent options for Server Rooms, Telecom & Control Rooms, Libraries, High Flammable Liquid Storage.
Three models are available for use in different size applications
Note : For ULC applications add “A” a suffix to model number.
ASD are capable of filtering false alarms and reduces maintenance in harshest environment and can work normal in dusty environment.
