AVESDA air sampling smoke detection system will provide the earliest possible warning of a fire in a portable substation or switch room.


Unlike point-type detectors, VESDA systems actively draw air samples to a central detector through a network of pipes. The sampling holes in the pipes can be placed near the most likely sources of electrical fire, and along the path that smoke will be carried by air flow from any air-conditioning system. This ensures the earliest possible detection of smoke. 


A VESDA early warning system specifically designed to address the risks in substations or switch rooms, will ensure the early detection of smoke and provide time to prevent latent equipment contamination.
