VESDA

• VESDA is a high sensitivity detection system that
  offers the quickest possible warning of a
  potential fire outbreak.
• It is a system that will ensure the continuity of
  your business, free of unwanted false alarms, by
  adapting to specific characteristics of any
  environment, providing excellence in performance
  which is owed to its high quality project.

VESDA PERFORMANCE

• VESDA performs by continuously drawing air
  through a network of tubes using a high
  efficiency suction ventilator. A sample of this
  air passes through a two-stage filter.
• First stage
• Dust and dirt particles are removed from
  the air sample before it enters into the laser
  detection chamber that analyzes the smoke.
• Second stage (Ultrafine Filtering)
• It has the sole function of providing clean
  air in order to protect the optical surfaces
  inside the detector from contamination and to
  ensure the stable calibration and long life span
  of the detector.
• After the filter stage, the air sample passes
  through the detection chamber, where it is
  exposed to a stable and controlling laser light
  source. If smoke is present, the light will
  disperse within the detection chamber and will be
  instantly detected and identified by
  high-sensitivity optical sensors.
