    (3) A safety control system, if required by Sec. 62.25-15;
    (4) Instrumentation to monitor system parameters necessary for the 
safe and effective operation of the system; and
    (5) An alarm system if instrumentation is not continuously monitored 
or is inappropriate for detection of a failure or unsafe condition.
    (b) Automation systems or subsystems that control or monitor more 
than one safety control, interlock, or operating sequence must perform 
all assigned tasks continuously, i.e., the detection of unsafe 
conditions must not prevent control or monitoring of other conditions.

that rely upon forced cooling for proper system operation must meet
