Abstract
An upright sprinkler is disclosed. The sprinkler comprises a housing having a conduit extending therethrough, a heat-sensitive valve assembly configured above the conduit, and a nozzle arrangement configured below the conduit. The nozzle arrangement is fluidically connected to the conduit via the valve assembly, such that actuation of the valve assembly enables the flow of a fluid from the conduit to the nozzle arrangement via the valve assembly and further sprays the fluid at different downward-facing angles through the nozzle arrangement.
