Weight 4.4 lbs (2 kg)     Information About VLF-250 The VLF-250 is part of the VESDA VLF series of aspirating smoke detectors engineered by Xtralis for compact spaces requiring ultra-sensitive detection. It incorporates patented ultrasonic flow sensing, laser-based absolute smoke detection, and a Smoke Dial™ for immediate visual feedback. Designed for compatibility with pre-engineered pipe networks, it provides versatile alarm threshold settings, AutoLearn™ functions, and event logging for up to 18,000 records. This detector is ideal for protecting small server rooms, telecommunications facilities, and mission-critical control spaces. Key Features: Early Warning Protection: Detects smoke at very low concentrations for areas under 250 m². Ultrasonic Flow Sensing: Provides accurate airflow readings, unaffected by temperature or contamination. Laser-Based Detection: Ensures precise and stable smoke measurements. Smoke Dial™ Display: Enables quick visual recognition of smoke events from a distance. AutoLearn™ Functions: Automatically adjusts smoke and airflow thresholds to the environment. Event Logging: Stores up to 18,000 time-stamped events for smoke, flow, faults, and detector status. Built-In Fault Diagnostics: Instant Fault Finder™ simplifies troubleshooting and maintenance. Flexible Pipe Options: Supports metric and American standard pipe sizes for installation versatility. The VLF-250 delivers the reliability and precision required for protecting small, business-critical environments where downtime or fire damage is not acceptable.
