From the 2010 edition of 13

8.1.2* System valves and gauges shall be accessible for operation, inspection, tests, and maintenance.

While it is technically permitted to be above a false ceiling, the years of headaches and the added cost of time lost trying to access it make it expensive. Very expensive.

The accepted industry practice is to locate the "System Riser" immediately on the entrance piping.
