NFPA 13, 2013 edition, 8.16.1.1.2.1 "Valves on connection to water supplies,
sectional control and isolation valves, and other valves in supply pipes to
sprinkler and other fixed water-based fire suppression systems shall be
supervised by one of the following methods:
(1) Central station, proprietary, or remote station signaling service
(2) Local signaling service that will cause the sounding of an audible
signal at a constantly attended point
(3) Valves locked in the correct position
(4) Valves located within fenced enclosures under the control of the
owner, sealed in the open position, and inspected weekly as part of an approved
procedure
I don't believe you would be required to electrically monitor or chain that
valve based on this section. FWIW, we always spec the valve on the backflow
test outlet piping to be supervised. Falls under the "good practice" category
in my opinion.
Nice to see someone providing means to full forward flow the backflow as
required.

Subject: RE: Butterfly valve, monitered or not?
Agree. However, this is similar to a fire pump test header control valve. The
NFPA 20 committee thought it was important enough to supervise the fire pump
test header valve. To me, this is a wasteful requirement but it is a
requirement. We need this requirement changed.

I am going to install a 4" butterfly valve on a sprinkler manifold. This will
give us an outlet to perform a Forward Flow. Does the valve need to be
monitored or will it be OK to use a chain to lock the valve in the closed
position?
