Abstract
A firefighting monitor having an acceleration sensitive shut off valve that responds to acceleration of the monitor to reduce water flow through the monitor. The acceleration sensitive shut off valve is self-contained and requires no contact with an external surface or device. The valve closing speed may be modulated by a dampener device that slows the rate at which the valve closes to avoid damage from water hammer.
