A firefighting installation including a valve and a network kept under vacuum in a standby position and flooded with water by an actuator if the installation is triggered in the event of a fire. The valve includes: a first conduit to be coupled with the vacuum network which includes the actuator; a second conduit to be coupled with a control device adapted to trigger the actuator by the effect of an air intake; a third conduit to be coupled to a sprayer; a shutter movable by the effect of a water pressure; and an elastically-deformable element adapted to hold the shutter in a rest position.

A dry drop to be mounted in a fire protection installation of the type having a network of vacuum sprinklers. The dry drop includes a tubular body, a shutter and a one-way valve. The tubular body defines an inner chamber and has: a first end; a second end; and an orifice located between the first end and the second end. The shutter is movable between: a shutoff position in which it shuts off the first nozzle; and a passage position in which it is cleared from the first nozzle. The one-way valve is intended to be mounted in the orifice to enable the pressurization of the inner chamber by injection of a gas into the inner chamber, the inner pressure holding the shutter in its shutoff position.
