A fire suppression apparatus includes a valve assembly connected to a container holding a fire suppressant. The valve assembly includes a valve body and a first disc. The valve body defines a passageway that extends between a first valve body end and a second valve body end. The first disc is disposed within the passageway. The first disc has a first disc body defining a perforation that extends completely through the first disc body.

A corrosion monitoring system of a fire protection system includes at least one first antenna and a processing circuit. The at least one first antenna receives a radio frequency (RF) signal through an internal volume of at least one pipe of the fire protection system. The processing circuit includes one or more processors and memory including computer-readable instructions that when executed by the one or more processors, cause the one or more processors to determine a signature of the RF signal, compare the signature to an expected signature, and determine, based on the comparison, that corrosion in the at least one pipe has occurred.

Fire protection systems and methods for ceiling-only high-piled storage protection. The systems include a plurality of fluid distribution devices disposed beneath a ceiling and above a high-piled storage commodity having a nominal storage height ranging from a nominal 20 ft. to a maximum nominal storage height of 55 ft. and means for quenching a fire in the storage commodity. The stored commodity to be protected may include exposed expanded plastics. The fluid distribution devices include a frame body having an inlet, an outlet, a sealing assembly, and an electronically operated releasing mechanism supporting the sealing assembly in the outlet.

Fluid control valve assemblies for use in fire protection sprinkler systems to control the flow of firefighting fluid to the system sprinklers. The assemblies include a pressure-operated fluid control valve having an internal fluid chamber in which fluid contained therein acts on an internal diaphragm to control the flow of fluid from an inlet to an outlet of the valve. An environment-responsive control device in fluid communication with the internal fluid chamber along a first fluid communication line controls the flow of fluid out of the fluid chamber to initiate actuation of the valve. A fluid-flow latch in fluid communication with the outlet of the valve along a second fluid communication line subsequently controls the simultaneous flow of fluid out of the fluid chamber and the actuation of the valve.

The invention concerns a pneumatic control device (1) for multi-zone fire extinguishing installations, comprising a control pressure inlet port (25) for connection to a control pressure source (105), in particular a pressurised gas container, a number (m) of first control pressure outlet ports (17) for connection to a corresponding number of extinguishing agent containers (107), a number (n) of second control pressure outlet ports (19) for connection to a corresponding number of zone valves (111), and a plurality of function modules (7, 9). It is proposed that the invention further includes a quantity control module (9) for the association of a selection of the first number of control pressure outlet ports (17) with a selection of the second control pressure outlet ports (19), and an electrical control valve module (7) which is controllable from the exterior for selectively opening or closing the second control pressure inlet ports (19) and which can be connected in particular in signal-conducting relationship to a fire alarm and/or extinguishing control station (103), wherein the function modules (7, 9) are operatively connected together.
