Imagine adding up all the years of experience, in various locales and different points of view (contractor, AHJ, mfrs, insurance, FPEs, etc) that are applied to situations like yours? P R I C E L E S S
Makes the membership dues of AFSA seem trivial in comparison....yes, it's that time of year. Although my health precludes me from flying at this time, I'd urge all of you to consider attendance at AFSa's convention, and membership if you haven't. George L.

NFPA 101 2012:9.7.2.1 Supervisory Signals. Where supervised automatic sprinkler systems are required by another section of this Code, supervisory attachments shall be installed and monitored for integrity in accordance with NFPA 72 , National Fire Alarm and Signaling Code, and a distinctive supervisory signal shall be provided to indicate a condition that would impair the satisfactory operation of the sprinkler system. Supervisory signals shall sound and shall be displayed either at a location within the protected building that is constantly attended by qualified personnel or at an approved, remotely located receiving facility. Also... IBC 2012:903.4 Sprinkler system supervision and alarms. All valves controlling the water supply for automatic sprinkler systems, pumps, tanks, water levels and temperatures, critical air pressures and waterflow switches on all sprinkler systems shall be electrically supervised by a listed fire alarm control unit. Exceptions: 1. Automatic sprinkler systems protecting one- and two-family dwellings. 2. Limited area systems serving fewer than 20 sprinklers. 3. Automatic sprinkler systems installed in accordance with NFPA 13R where a common supply main is used to supply both domestic water and the automatic sprinkler system, and a separate shutoff valve for the automatic sprinkler system is not provided. 4. Jockey pump control valves that are sealed or locked in the open position. 5. Control valves to commercial kitchen hoods, paint spray booths or dip tanks that are sealed or locked in the open position. 6. Valves controlling the fuel supply to fire pump engines that are sealed or locked in the open position. 7. Trim valves to pressure switches in dry, preaction and deluge sprinkler systems that are sealed or locked in the open position.

NFPA 20 requires the pump enclosure to be supervised or controlled but I found nothing requiring valve supervision. I don't have access to the codes on line right now so I can't look it up without going old skool using a book and that's too much trouble for Friday. I think IFC requires supply valves to be supervised.

The test outlet control valves shall be supervised closed. includes these valves, otherwise you could leave the meter bypass open and have no pressure. Typically we'd lock a valve like this open. One could argue that the test outlet control valve is defined as the test header control valve, but there's a checklist in the standard that makes mention that test header AND meter bypass valves need to be supervised (form S2.2).

Is there a general requirement that all valves in a pump room be supervised? I am wondering about the valves in a flow meter loop that are normally closed.
