Control facilities for commissioning and operation of the water cooling, air handling and fire detection of LEP

This paper reports on the various processes (water cooling, air treatment and distribution, fire detection) which the CV group is in charge of, that are integrated in the general LEP control system. The choices of the solutions, for both hardware and software, which have been adopted at the different levels of the control hierarchy are discussed. The reason for such choices has been to take into account the various constraints attached to the running of industrial processes, both locally and remotely, in an accelerator control environment
