A-47a Extended Coverage Horizontal Sidewall Sprinkler - GL8114
Concealed Extended Coverage Horizontal Sidewall For Light Hazard Occupancies Model GL8114
Description and Operation
The Globe Quick Response GL8114 Extended Coverage Horizontal Sidewall Adjustable Concealed Sprinklers for light hazard occupancies have the lowest profile available for this type of sprinkler, providing an aesthetically pleasing design. They can be installed wherever standard extended coverage horizontal sidewall sprinklers are specified when allowed by the applicable standards, and in accordance with NFPA 13. The sprinkler has 1/2” of adjustment for ease of installation. All that is seen on the wall is a 3 1/4” diameter wall plate color finished to match the specifiers exact requirements. In addition to making the sprinkler much less noticeable, the wall plate assembly also provides protection for the sprinkler from flying or hanging objects.
The heart of Globe's Model GL Series sprinkler proven actuating assembly is a hermetically sealed frangible glass ampule that contains a precisely measured amount of fluid. At the rated temperature the internal pressure within the ampule exceeds the strength of the glass causing the glass to shatter. This results in water discharge which is distributed in an approved pattern. The wall plate is soldered to the sprinkler’s special upper support assembly in three places. Upon the application of sufficient heat, the plate falls to the floor exposing the quick response sprinkler.
