Product Description P/N: VLF-250
Description
The VESDA VLF-250 is an advanced very early warning smoke detector designed for small, business-critical environments up to 250 m² (2,690 sq. ft.). It continuously samples air through a pipe network and uses laser-based light scattering technology to detect even the smallest traces of smoke. With intuitive displays and built-in fault diagnostics, the VLF-250 ensures fast response, reliable performance, and simplified serviceability.

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.
