VESDA VLF-250 Detector

VESDA VLF VESDA VLF 250 detector is a very early warning smoke detector to protect small business critical environments of less than 250 m2 sq ft detector works by continually drawing air into sampling holes in a pipe The air is ltered and passed into a detection chamber where light technology detects the presence of very small amounts of smoke status information is communicated on the detector display and via or optional interface cards operation VLF can be installed and commissioned out of the box without the need a special interface or software programming tools operation the unique Smoke DialTM display provides the user with an understanding of a smoke event even from a distance Should a fault the user simply opens the eld service door and activates the Instant Finder feature to determine the speci c fault condition This information then be passed onto their re service company ensuring that service arrive onsite fully prepared Flow Sensing patent pending Ultrasonic Flow Sensing used in the VLF provides a reading of the sampling pipe ow rate The system is immune to air and pressure changes and is unaffected by contamination The is the rst air sampling smoke detector to use ultrasonic ow sensing Out of the Box Installation and Commissioning Ultrasonic Air ow Sensing Laser Based Absolute Smoke Detection Pre engineered pipe network designs Programmable
