A fire protection sprinkler is provided, including a body having an output orifice, a closure element or seal cap to seal a flow of fluid from the output orifice, and a thermally-responsive element positioned to releasably retain the seal cap. A clip, having a first portion and a second portion, is provided, the first portion being engaged with the closure element, and the second portion being in contact with the sprinkler body such that upon actuation of the fire protection sprinkler, the closure element rotates about a pre-determined axis and moves away from the sprinkler body to permit flow of fluid from the output orifice. In particular, the portion of the sprinkler body which the clip contacts is a detent provided on the wrench boss of the sprinkler.

A water spray base for fire includes a water inlet pipe, a fixed base, a water outlet pipe, and an adjusting device so as to feature an easy and convenient way of adjusting the angle of elevation or depression of the water spray base and a light weight.

A fire-suppression technology system has a tank with outlet and inlet orifices. A reservoir has a dispensing orifice. The tank receives water. The reservoir receives a quantity of powder adapted to be converted to a fire-suppressing fluid when mixed with water. A pump operatively couples the tank and the reservoir. A hose is operatively coupled to the pump. A spool is supports the hose. A primary path of travel constitutes a closed loop path between the tank and the pump and the reservoir to create a fire-suppressing fluid. A secondary path of travel constitutes an open path for dispensing the fire-suppressing fluid from the tank and the pump toward a region to be controlled.

A computer-implemented method that, when executed by data processing hardware, causes the data processing hardware to perform operations. These operations include receiving alarm signals associated with a thermal event, receiving thermal imaging data for the observation zone associated with the thermal event, evaluating the thermal imaging data to determine the location and/or the area of the thermal event within the observation zone. The operations also include obtaining a configuration record that includes configuration parameters for a retardant dispenser associated with the observation zone. Using the configuration parameters, the operations include instructing the dispenser to provide a retardant to the thermal event.

A wall-mountable spray head unit (11) is described. The spray head unit comprises a rotatable spray head assembly (8.sub.1, 8.sub.2; FIG. 9, 8.sub.3; FIG. 17) which comprises a spray manifold (18.sub.1, 18.sub.2; FIG. 9) rotatable about a first axis (17), a spray nozzle (19) supported by the spray manifold and orientated to deliver fire-suppressant material radially in a plane in a plane defined by the first axis and a second axis which is perpendicular to the first axis, and at least one thermal sensor (20).

A method for improving the hit accuracy of fire detection systems controlled by infrared and video fire detection by means of a first IR/video camera system for the first detection unit (D1) to ensure continuous fire detection and a second IR/video camera system for the second detection unit (D2) to ensure automatic target tracking with respect to the source of fire, as well as to an extinguisher launcher (A) rigidly connected to the second detection unit. The method is characterised by steps through which video/infrared-controlled extinguishing systems can be precisely hit with regard to the target precision, and fires can be combated as quickly as possible, even in the early phase, with as little extinguishing agent as possible.

A water spraying fan for firefighting. The water spraying fan includes a fan mechanism mounted onto a rotatable surface attached to a base. The fan mechanism has a plurality of fan blades connected to a power source and adapted to rotate quickly, creating a strong air flow when powered on. A cage encloses the fan blades and includes one or more circular manifolds secured to a front side and positioned concentric to the fan blade axis. The manifolds contain a plurality of nozzles that are configured to disperse a liquid, such as water. The manifolds are connected to a water source via a flow control box. When activated, water flows out of the nozzles and is carried across an extended distance via the water pressure and the strong air flow created by the fan mechanism. The water spraying fan can be rotated or tilted to achieve optimal positioning.
