Public address (PA):
This system is for audio informing.

CCTV system:

This system is worked by using digital analogue and digital clock that will be installed in the station precinct, the exact time will be informed to the public.

  Synchronize data hierarchy (SDH):
This Is the information transfer system from passenger station to control center.
This system transfers all information about the above mentioned subsystems through the optic fiber cable net work to control center.

  
Explanation of GIS project:
This project contains ,equipment supplement ,study, construction parts ,Insulation and GIS running, in shiraz metro .this post supply the main part of system power consumption was located beside the station 14,and at the Namazi Sq margin .among 39 MVA shiraz consumption power ,25 MVA supplied at this station. input of this post from the shiraz university 230/63KVand it's input is feeding BSS. this gas station is controlled by the way of DCS.
