Consider a multi-story building with floor control valves (FCV) at each level.
Is a main drain test required to be performed at each of the floor control valves and tagged at startup? Is a hydraulic placard required at each floor control valve? If so, is the base of riser pressure to be the pressure at floor control valve or at the base of riser in the sprinkler riser room? Is it allowable to hang each of the floor's hydraulic placard together at the main riser in the sprinkler riser room? Thanks in advance. Sent in anonymously for discussion.

"Main Drain" is located at the building's sprinkler system main riser. As such this test is only required at this one point. The drains at each floor control valve shall still be operated.

For my own preferences I do a printed vinyl sticker at each floor control valve with machine print.

The question of placard placement is an important question, and one that has been interpreted in different ways. We recently asked the NFSA's "Expert Of the Day" this very question and their response was as follows: "No, the data plate does not need to be at each control valve if they are not different design criteria. NFPA 13, 2019 Section 28.5.2 States that the sign shall be placed at the alarm, dry, preaction, or deluge valve supplying the corresponding hydraulically designed area. If the entire mall is fed from the same watersupply and the design criteria is the same throughout, only the main riser would require the sign. Note that the 2022 edition of NFPA 13 requires a dataplate at all system risers. A riser is defined as aboveground horizontal or vertical pipe between the water supply and mains, cross or feed that contains a control valve, gauge, drain and alarm device.
