VESDA (Very early smoke detection devices) works by continuous sampling of air to detect particles emitted by fires in their very early stages. VESDA is configurable to trigger at 5 different severity levels, providing customization for different sites and applications.
Fire suppression is done by utilizing Nitrogen which effectively puts out fires by removing the oxygen from the fire. Nitrogen is inert, colorless, odorless and do not cause any harm to electronic equipment.
