  • Page 9: Introduction

    VESDA VLS Product Guide Introduction The VESDA VLS is an aspirating smoke detector providing very early warning of fire conditions by drawing air samples through an air sampling pipe network. The detector chamber can detect presence of smoke at very low concentrations. The embedded and PC software complimenting the VESDA VLS provides a wide range of user defined parameters and reporting capabilities.

  • Page 11: Operation

    An integrated Aspirator draws air in the sampling pipes through a Pipe Inlet Manifold (up to four pipes can be connected to a VESDA VLS detector). For further information on air sampling pipe network, refer to the Pipe Network Design and Installation Manuals.

  • Page 12: The Scanning Function

    When smoke is detected at a higher level than the scan threshold, for a period exceeding the configured scan delay (0 to 10 seconds), the detector performs a fast scan. During the fast scan operation the VESDA VLS samples air from each sector (pipe) separately by controlling the scanner valves in the inlet manifold. The fast scan sequence for each pipe is approximately 4 seconds.
  • Page 13 VESDA by Xtralis VESDA VLS Product Guide 2.1.4 Sector Factor By setting appropriate sector factors it is possible to set different alarm thresholds for each of the four sectors. The detector uses the sector factor to automatically calculate the alarm thresholds appropriate for each sector based on the configured alarm thresholds.
