This should be troubleshooted.
Very common to have a defective check valve on the compressor or air supply line, causing pressure to drop and trip the pressure switch.

I don't have NFPA 13 in front of me now, But the chapter you are referring to is specific for seismic protection.
In the USA, the Building Code determines if the area is in a seismic zone and the Layout Technician of the sprinkler system uses NFPA 13 Chpater on Seismic Protection.
In your case...
