    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 a 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 VESDA LaserSCANNER Product Manual ® Each pipe inlet in the manifold has a valve that can open or close the flow of air to the pipe. The scan function controls the opening and closing of the valves to detect the smoke carrying pipe.

  • Page 11: The Scanning Function

    VESDA ® LaserSCANNER Product Manual The Scanning Function The LaserSCANNER is designed to sample air from different sectors and to identify through a scanning process the sector reporting presence of smoke. Scanning During normal operation the scanner valves remain open and the LaserSCANNER draws air from all the pipes.

  • Page 12: The Scanner Valve Test

    ® The Scanner Valve Test The VESDA LaserSCANNER performs a scanner valve test when first powered up. Thereafter a valve test is performed every alternate Tuesday at 12:00 hours. During the valve test each valve is individually closed and opened to ensure its proper functioning. Any improper functioning is reported as a fault (refer to the VESDA Troubleshooting Guide for fault descriptions and troubleshooting).
