First Level Trigger System based on the active target of silicon strip
detectors and scintillation hodoscope for 'Spectrometer and Vertex detector'
experiment is described. The implementation of lookup table method for data
selection in trigger system is shown. The efficient operation of the first level
trigger system in the statistics run on Serpukhov accelerator has been
demonstrated.
