Pre-action vs dry pipe sprinkler systems, high and low air pressure monitoring.

 

I am designing a new pre-action system that is arranged for double interlock with smoke detection for activation of solenoid. I know that per NFPA 72, dry pipe sprinkler systems require high and low air pressure alarms to be monitored but is this also true for pre-action systems? I know low air pressure condition must be monitored but I am unsure if high air pressure condition must be monitored for pre-action sprinkler systems.
