In the IBC (2006 Edition) paragraph 903.4 "Sprinkler system monitoring and alarms", states; All valves controlling the water supply for automatic sprinkler systems, pumps, tanks, water levels and temperatures, critical air pressures and water-flow switches on all sprinkler systems shall be electrically supervised. And paragraph 903.4.1 Signals, requires that; Alarm, supervisory and trouble signals shall be distinctly different and automatically transmitted to an approved central station, remote supervising station or proprietary supervising station as defined in NFPA 72 or, when approved by the fire code official, shall sound an audible signal at a constantly attended location.
Paragraph 903.4.3 "Floor control valves" states that; Approved supervised indicating control valves shall be provided at the point of connection to the riser on each floor in high-rise buildings. The IBC does require the supervision of fire sprinkler systems especially where IBC sprinkler trade off are used in the design of the building. Have a fire safe day.

The question is MUST it be a system? As for the components one elects to put on each floor, NFPA 13 does not require all the stuff shown in A.8.17.4.2(b) for a floor control valve (actually the criteria in 13 that the annex material is attached to is not about floor control valves). Other sections indicate the type of supervision for floor control valves but nothing in 13 says you have to have it. Now the IBC requires a control valve but then it is real sloppy on the alarm requirements (many things interpreted to mean a flow switch per floor but nada explicitly stating on it). A tad amusing. There are significant impacts on whether each floor is a system especially for NFPA 25.
