A VESDA fire alarm system can detect very subtle amounts of hazardous gases, which could harm people and property. How does it work? By continually drawing air from within a building into a network of pipes, by means of a highly efficient aspirator, early warning fire detection is possible. Air samples taken pass through a duel stage filter system, which removes any dirt or dust before the air is delivered to a smoke detection chamber. The system then uses lasers to detect smoke and other combustible gases. How does laser smoke detection work? Once dust and dirt has been effectively removed from an air sample, and the air sample reaches the laser detection chamber, the air sample is then exposed to laser light. If smoke or other unseen combustible gases are present in the chamber, the light from the laser will scatter. Because the laser detector is calibrated, any deviation or dissipation of the lasers light will trigger a fire alarm. A VESDA fire alarm system is programmed to communicate constantly with its fire alarm control panel. Once the signal is received, it is then visually presented as a bar graph on the control panel and can be monitored. MAINTAINING A VESDA FIRE DETECTION SYSTEM - Vesda fire alarm system is a made up of sophisticated equipment, and like any precision piece of equipment, maintenance is required. Fortunately, the manufactures specification to maintain the fire alarm system is manageable. When you absolutely need a fire detection and alarm system to be reliable, functional at all times and effective at detecting smoking fires, then the VESDA fire alarm system is right for you. Fire and Wire is here to assist you.
