Vesda VLF-500 LaserFOCUS-500 Detector with Display
Vesda VLF-500 LaserFOCUS-500 Detector with DisplayThe VESDA LaserFOCUS detector is a very early warning smoke detector designed to protect small business-critical environments of less than 500 m2 5000 sq. ft.The detector works by continually drawing air into sample holes in a pipe network. The air is filtered and passed into a detection chamber where light scattering technology detects the presence of very small amounts of smoke.Detector status information is communicated on the detector display and via relays or optional interface cards.Out-of-the-box OperationThe VESDA LaserFOCUS can be installed and commissioned out-of-the-box without the need for a special interface or software programming tools.In operation the unique Smoke Dial display provides the user with an instant understanding of a smoke event even from a distance. Should a fault occur the user simply opens the field service door and activates the Instant Fault Finder feature to determine the specific fault condition. This information can then be passed onto their fire service company ensuring that service technicians arrive onsite fully prepared.Ultrasonic Flow SensingThe patent-pending Ultrasonic Flow Sensing used in the LaserFOCUS provides a direct reading of the sampling pipe flow rate. The system is immune to air temperature and pressure changes and is unaffected by contamination. VESDA is the first air sampling smoke detector to use ultrasonic flow sensing.Key FeaturesOut-of-the-Box Installation and CommissioningUltrasonic Airflow SensingLaser-Based Absolute Smoke DetectionPre-engineered pipe network designsProgrammable Alarm ThresholdsDual Stage Air FiltrationInstant Recognition DisplayInstant Fault FinderAutoLearn SmokeAutoLearn FlowField Service Access DoorMultiple Event Logging in separate logsEvent log up to 18000 eventsOfflineonline configuration capabilityUp to 500 m2 5000 sq. ft. coverage
