Course Description 

Process alarm and shutdown systems perform two basic functions: the first is to provide an alarm or warning that a process system is operating outside ideal or designated parameters – usually where a process variable measurement is trending outside set conditions.

The second is to protect people, the environment and facilities by initiating a shutdown and sounding of alarms.
