Air Sampling

Air sampling detectors can detect a fire at its earliest stage by actively pulling air into a detection chamber through a piping network that runs from the device to the protection area. Particles that are formed in the early stages of combustion—even before smoke or fire is visible—are detectable through this proactive system.

Common Applications:

  • Telecommunication centers
  • Data centers
  • Clean rooms
  • Server rooms
  • Theaters
  • Warehouses
  • Indoor stadiums
  • Convention Centers

Threats Reported:

  • Smoke
  • Fire

For decades, the VESDA range of aspirating smoke detectors (ASD) have been recognized as the best in the world. The VESDA -E models have sensitivity up to 15 times greater than previous models. They are ideal for a wide variety of applications and include multi-port addressability, increased connectivity and expansion options, and field upgradability. VESDA-E’s sensitivity, flexibility, reliability, programmability, and expandability provides customers with superior performance and protection, while lowering the total cost of ownership.


Invented by Xtralis, VESDA is a very early warning aspirating smoke detection (ASD). Customers worldwide rely on VESDA when business continuity is imperative, environments are challenging, and time is required to ensure safe and orderly evacuation. VESDA ASD systems also can be equipped with modules to detect hazardous / combustible gases to extend their value beyond smoke detection to include gas detection and environmental monitoring.

Gas Detection Products

VESDA gas detection systems utilize the air sampling pipe network to deliver superior gas detection via multiple-hole (multi-port) sampling. The combined solution provides reliable detection of gases for occupant protection and process monitoring while simultaneously ensuring protection against fire threats. VESDA ASD systems are also used with modules to detect hazardous / combustible gases. There are several products in this line, and one is specifically designed for lithium-ion battery systems. Available products include:
