VESDA LaserFOCUS by Honeywell (formerly Xtralis) is the compact entry point of the VESDA aspirating smoke detection family, engineered for small-to-medium protected areas. The VLF-500 is specified in server rooms, telecommunications rooms, switch rooms, retail back-of-house, clean rooms, and heritage spaces where very early smoke detection is required but the protected area does not justify a higher-capacity VEP or VEU detector.
