§ 901.6.3.2. Above-Ground Water Control Valve Supervision.

Latest version.

Above-ground water control valves used for water based fire protection systems, including private service mains and appurtenances, shall be mechanically supervised by locking the valve in the fully open position using a cable or chain and a non-case hardened lock, or by other approved means, when the valve is not electrically supervised. Detachable wrenches for post indicator valves shall be secured in place by the use of a non-case hardened lock.
