A fire suppression sprinkler adapted to receive arcuate surfaces of a grooved coupling is retainable to the coupling in a pre-assembled state. The coupling joins the sprinkler in facing axial end to end relation directly to grooved pipe. The sprinkler has a monolithic body which defines a bore having an inlet and an outlet. A groove, positioned between the inlet and the outlet extends around the body. A projection, positioned between the groove and the outlet also extends around the body.

A thermal trigger assembly for remote mechanical actuation of another fire protection system component includes an activation component having a base and a movable member. A bias member biases the movable member from a preactivation to an activated position with respect to the base. A thermally responsive element retains the movable member in the preactivation position until a predetermined thermodynamic condition is reached, when the thermally responsive element loses structural integrity. A flexible connector includes a flexible hollow outer cable housing with one end configured to be stationarily (preferably fixedly) connected with the base. A flexible cable is inside the outer cable housing for sliding movement therein and has one end configured to be stationarily (preferably fixedly) connected with the movable member. The flexible cable is moved with respect to the outer cable housing by movement of the movable member upon loss of structural integrity by the thermally responsive element.

A valve comprises a housing having a main inlet, a detection port and an outlet, each providing a channel extending from an exterior of the valve into a hollow interior defined in part by the housing. The inlet is arranged, in use, to be in fluid communication with the interior of a pressurised cylinder of extinguishant fluid. The detection port is arranged, in use, to be in fluid communication with a fire detection system. The valve has two valve parts which are relatively movable between a first position, a second position and a third position. In the first position, a face seal prevents communication between the high pressure chamber and the low pressure chamber, in the second position, the face seal is in an unsealed position and allows communication between the high pressure chamber and the low pressure chamber, and in the third position, the face seal prevents communication between the high pressure chamber and the low pressure chamber.

Installation and protective devices for fire protection sprinkler assembly having a support cup is disposed about the sprinkler assembly. A protective cap engages the support cup to define an internal volume to enclose the sprinkler therein and protect operational components of the sprinkler during storage, transport, installation and when awaiting to be placed into service. The protective cap defines a tool path with slots of the protective cap in fluid communication with the internal volume. The protective cap and tools are configured to cooperate with one another to permit the tool to adjustably navigate within the internal volume to access the protected sprinkler for installation or adjustment of the sprinkler frame and/or for removing the protective cap.

An embodiment of a fire-suppression water-intake valve includes a receptacle and a valve assembly. The receptacle is configured to receive a sprinkler head. And the valve assembly is configured to close in response to removing a sprinkler head from the receptacle, and is configured to open in response to installing a sprinkler head in the receptacle. Such a fire-suppression water-intake valve can allow quick and easy removal and installation of a fire-suppression sprinkler head without shutting a water supply to the valve.
