I need to know if shutoff valves (normally open) of firefigthing system are included in section 4.1.2 "All devices and materials used in stand pipe systems shall be listed, ...". If not by that section wich NFPA says otherwise.

NFPA 14; 4.1.3 says "Components that do not affect system performance, such as drain piping, drain valves, and signs, shall not be required to be listed".
The shutoff valve I ask is normally open and does´t affect system performance, so it should be un-listed?

Normally it is listed
Normally it is able to be monitored for tamper

What does your shut-off valve close? Is it an isolation valve between standpipes, is it a shutoff valve on a drain, or is it a valve used by firefighters to control the flow of water through hose streams?
