Air Sampling Based High Sensitivity Smoke Detection System

Listing ID #1832753

Vesda a fire detection system is that offers the earliest possible warning of a potential fire. Vesda work by continually drawing air into the pipe network via a high efficiency aspirator. A sample of this air is then passed through a dual stage filter. The first stage removes dust and dirt from the air sample before it allows the sample to enter the laser detection chamber for smoke detection. From the filter, the air sample is passed through to the calibrated detection chamber where it is exposed to a stable controlled laser light source. When smoke is present, light is scattered within the detection chamber and is instantly identified by the highly sensitive receiver system. The signal is then processed and presented via a bar graph display, alarm threshold indicators andor graphic display. The vesda detectors are able to communicate this information to a fire alarm control panel, a software management system or a building management system via relays or a high level interface (hli). Vesda key features the latest in laser technology patented high efficiency aspirator world?s widest sensitivity range dual stage dust filtration up to 4 levels of alarm
