    You will also find instructions on installing, cabling and powering up the detector. This manual is for anyone involved with the design, maintenance and purchasing of an Xtralis VESDA system. It is assumed that anyone using this manual has knowledge and the appropriate certification from the local fire and electrical authorities.

  • Page 10: Operation Of The Vls

    Xtralis VESDA Xtralis VESDA VLS Product Guide ® 3 Operation of the VLS An air sampling pipe network with sampling holes at appropriate spacing collects air samples from a protected area. An integrated Aspirator draws air in the sampling pipes through a Pipe Inlet Manifold (up to four pipes can be connected to a VLS detector).
  • Page 11 Xtralis VESDA ® Xtralis VESDA VLS Product Guide Any smoke detected in the laser detection chamber is signaled to the main processor card. If the presence of detected smoke is higher than the set thresholds it will be reported as an alert, action, fire 1 or fire 2 Alarm depending upon the set alarm thresholds.

  • Page 12: The Scanning Function

    Any improper functioning is reported as a fault (refer to the Xtralis VESDA Troubleshooting Guide for fault descriptions and troubleshooting). It is possible to simulate a valve scan test by pressing the Silence/Scan button on the Display Module for two seconds, or selecting the scan test option under the diagnostics menu on the LCD programmer or the device menu on the PC software.

  • Page 13: Sector Factor

    Xtralis VESDA ® Xtralis VESDA VLS Product Guide 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.

  • Page 14: Display Module

    Xtralis VESDA Xtralis VESDA VLS Product Guide ® Display Module The VLS Display Module is mounted either on the detector front cover or at a remote location in a remote mounting box or a 19” subrack. It provides a visual representation of the smoke levels and the four alarm stages for the assigned detector.
  • Page 15 Xtralis VESDA ® Xtralis VESDA VLS Product Guide ALERT: When lit this LED indicates that the smoke level is above the alert threshold. This means the detector has identified very early stages of a fire condition and/or that the smoke level in the area is above normal.
