A fire suppressing device including a torus container with a main body defining an interior chamber and a discharge port, the interior chamber configured to receive and retain metal organic framework materials. The fire suppressing device also includes an inductor coil extending through the interior chamber of the torus container and surrounding the metal organic framework materials. The inductor coil is configured to heat the metal organic framework materials to form a fire suppressing substance that is conveyed through the discharge port.

Described is signalling device for extinguishers or hydrants, comprising a first valve body connected to a tank of liquid and/or powder product to be dispensed, a second valve body connected to a hose equipped with a nozzle for dispensing product and a handle for activating the dispensing of the product equipped with a control lever; inside the handle is housed a safety plug shaped in such a way as to keep the control lever in an inactive position. The plug has, at a relative end portion, a magnet, which activates a sensor present on an electronic card located inside the control lever, designed to detect the presence of the plug. Moreover, the plug is made of transparent plastic material and at least one LED is positioned on a base facing a lower portion of the plug, in such a way that the LED produces a luminous emission which spreads for the entire plug, thereby operating as a luminous wave guide.

A discharge valve includes a valve body, a closure, and a non-rigid valve member. The valve body has a bore that extends between an inlet and an outlet. The closure is seated to the valve body and extends to the bore. The non-rigid valve member has an interior and is fixed within the bore between the inlet and the outlet of the valve, the interior of the non-rigid valve member in fluid communication with the closure for expansion and contraction of the non-rigid valve member. Fire extinguisher assemblies and methods of making fire extinguisher assemblies are also described.

A fire suppression system includes a feed port and a channel to couple the feed port to an actuation chamber. A solenoid valve controllably blocks a connection between the feed port and the channel. Pressure from the feed port builds up in the actuation chamber based on the solenoid valve unblocking the connection. A piston is in communication with the actuation chamber. The system also includes an inlet port closed off by a disc. The piston travels through the inlet port and burst the disc based on the pressure in the actuation chamber. An outlet port is coupled to the inlet port.

A push-to-connect and quick-release coupler can be provided. In an example, the coupler can be used with or coupled to a fire extinguisher nozzle. The coupler can include a socket body and an automatic locking assembly. In an example, the locking assembly can include a collar movably coupled with the socket body, and a movable locking element. In a locked configuration, a fire extinguisher nozzle can be retained in the socket body, and the collar can be disposed in a first position, and the locking element can be biased by the collar toward the plug portion of the fire extinguisher nozzle. In a released or unlocked configuration, the nozzle can be removable from the socket body, the collar can be disposed in a second position, and the locking element can be unbiased by the collar.
