VLF-500-00 | VESDA Very Early Warning Aspirating Smoke Detector

Vesda · Fire & Life Safety

Description  The VESDA VLF-500-00 is a very early warning aspirating smoke detector designed for small, business-critical environments up to 500 m² (5,380 sq. ft.). It continuously samples air through a pipe network, using laser-based light scattering technology to detect extremely low levels of smoke. This intelligent system ensures rapid detection of incipient fires, providing superior protection for sensitive applications such as data centers, control rooms, and clean environments.     Technical Specifications  Condition New/Never Used Surplus Brand VESDA (by Honeywell / Xtralis) Category Fire Safety Part Number VLF-500-00 Subcategory Aspirating Smoke Detector Detection Principle Laser-based light scattering (very early warning) Coverage Area Up to 500 m² (5,380 sq. ft.)

It operates by drawing air from sampling points into a centralized detection chamber, where smoke particles are measured using laser-based optical sensing. This model incorporates patented Ultrasonic Flow Sensing, immune to air pressure or temperature fluctuations, ensuring stable performance. The detector’s Instant Fault Finder™ and AutoLearn™ functions simplify setup and diagnostics, while its intuitive Smoke Dial™ display allows quick identification of smoke levels or system faults without specialized tools. Key Features: Laser-Based Detection: Employs high-sensitivity laser optical sensing to detect minute smoke particles. Ultrasonic Flow Sensing: Provides precise airflow monitoring unaffected by contamination, temperature, or pressure. AutoLearn™ Algorithms: Automatically sets optimal smoke and flow thresholds based on environmental conditions. Instant Fault Finder™: Simplifies troubleshooting by pinpointing specific system faults for faster maintenance. Intuitive Smoke Dial™ Display: Provides real-time visual feedback of smoke levels for easy interpretation. Multiple Event Logs: Stores up to 18,000 events for detailed operational history and compliance reporting. Programmable Alarm Thresholds: Allows custom configuration for Alert, Action, Fire 1, and Fire 2 levels. Compact Coverage: Protects areas up to 500 m² (5,380 sq. ft.) with flexible pipe network design. The VLF-500-00 delivers the reliability and precision required for mission-critical smoke detection in confined or high-value environments.
