It is proposed for the firefighting nozzle arrangement ( 25 ) to have at least one central tube ( 27 ), which is arranged within the housing ( 7 ) and oriented in an output direction (W), and which is fluidically connected to a horizontally and vertically pivotable distributor device ( 37 ) by means of a supply line section ( 44 ), wherein the supply line section ( 44 ) is designed with a harmonic curvature.

Fire protection systems for a rooftop solar panel installation with solar panels. The fire protection system has a group of water spray nozzles with a metric K-factor of 20 or less to discharge firefighting fluid to a coverage area of the rooftop solar panel installation, a fluid pipe system connecting the group of water spray nozzles to a fluid supply for providing firefighting fluid, a fire hazard detection system with at least one fire hazard detector configured to monitor the coverage area, and at least one detection control unit to generate an alarm signal upon detection of a fire hazard within the coverage area, a valve unit configured to control passage of the firefighting fluid from the fluid supply, wherein the coverage area is at least 500 m 2 , and the group of water spray nozzles is configured to discharge the firefighting fluid received from the fluid supply to the coverage area with a normalized fluid application rate of 15 mm/m 2 /min or less.

A device for securely storing liquid hazardous material. The device includes a housing for receiving a storage container for the liquid hazardous material. The housing has a rear protective wall which is designed to protect a rear side of the storage container, a first and a second side protective wall which are designed to protect two side walls of the storage container, and a front protective wall which is designed to protect a front side of the storage container, and a fluid-permeable platform which is designed as a supporting surface for the storage container within the device, and a collection region which is fluidically connected to an inner region of the housing. The front protective wall is designed to be arranged on the storage container in order, when the storage container is received in the device, to form the housing.

System and methods to provide ceiling-only suppression fire protection of up to fifty feet (50 ft.) of rack storage of cartoned unexpanded plastic commodities and less hazardous commodities, such as for example, Class 1, Class 2, Class 3, Class 4 and/or combinations thereof beneath a ceiling having a maximum ceiling height up to fifty-five feet (55 ft.). The systems and methods provide for hydraulic and system parameters that include a hydraulic design area based upon five to no more than twelve hydraulically most remote sprinklers spaced at a preferred sprinkler-to-sprinkler spacing of eight to ten feet (8-10 ft.) coupled to two to four branch lines tied to a common cross main supply pipe of firefighting fluid.

The invention concerns a pipe arrangement comprising a protective device for protecting against environmental influences, the pipe arrangement comprising: a) a pipe joint which includes at least two pipe ends ( 1, 2 ) which are fixed together by means of a mechanical joint ( 3 ) and in which the pipe ends ( 1, 2 ) and also the mechanical joint are closed with a deformable hollow body ( 4 ), or b) a pipe ( 1 ) with a pipe opening ( 14 ), for example a leak, through which a medium which is disposed within the pipe can escape, wherein the pipe ( 1 ) is enclosed by a deformable hollow body where the pipe opening ( 14 ) is and wherein the pipe ( 1 ) is covered by the hollow body ( 4 ) in a predetermined portion on both sides of the opening ( 14 ), or c) a pipe having a pipe opening on which a sprinkler of a sprinkler installation is mounted, wherein the pipe ( 1 ) and also the sprinkler outlet is enclosed by a deformable hollow body ( 4 ) where the sprinkler is fixed to the pipe so that the hollow body ( 4 ) surrounds both the pipe end ( 1 ) and also the sprinkler outlet and a part of the sprinkler, or d) a pipe of a pipe system, wherein the pipe ( 1 ) is formed from two pipe portions which are connected together in positively locking relationship, for example by a welding process, a soldering process, a gluing process or the like, and wherein in the region of the positively locking connection the pipe is enclosed or covered by a deformable hollow body, or e) a pipe of a pipe system, wherein the pipe is enclosed by a deformable hollow body and where the hollow body ( 4 ) encloses the pipe ( 1 ) the pipe is carried by a suspension ( 13 ) which preferably has a material different from the material of the pipe.

A device and method for protecting and installing a fire protection sprinkler. The protective and installation device has two discrete protective members coupled to one another about the sprinkler by a releasable locking arrangement defined by a connection between the two discrete protective members. At least one of the members includes a torque assist portion for applying torque to the fire protection sprinkler and each of the members includes a deflector protection portion.

A fire protection system, which is configured to communicate with a central device of the fire protection system and with at least one user terminal in order to grant the user terminal access to at least part of the system information of the fire protection system, wherein the service device processes the system information for transmission to the at least one user terminal, transmits it to the user terminal and adjusts it in response to user input. A fire protection system configured to communicate with such a service device, a system for operating a fire protection system with such a service device, and a corresponding method for operating the fire protection system is provided.

Differential-type dry pipe valves for fire protection systems are provided. The valve includes a body with a clapper assembly disposed in an internal passage of the valve body between an inlet and an outlet. The clapper assembly is movable between a closed position and an open position to respectively prevent and permit fluid flow through the passage from the inlet to the outlet. With the clapper assembly in the open position, an internal mechanism is positioned to stop the clapper moving to the closed position. The valve includes a resetting assembly having a knob exterior to the body. Translation of the knob toward the outlet moves the internal mechanism which permits the clapper assembly to move to the closed position.

Institutional sprinkler assemblies are provided that includes a sprinkler housing and protective cap arrangement to protect a thermally responsive shielding trigger. The sprinkler housing and trigger arrangement provide for an annular buffer to protect the trigger. The institutional sprinkler assemblies include configurations for installation in pendent and horizontal and orientations.
