A-76 Extended Coverage Light Hazard Pendent Sprinkler - GL8159
Extended Coverage Light Hazard Model GL8159 Pendent
Description and Operation
The Globe Model GL8159 Extended Coverage Pendent Sprinkler for Light Hazard occupancies is a low profile yet durable design which utilizes a 5mm frangible glass ampule as the thermosensitive element. While the sprinkler provides an aesthetically pleasing appearance, it serves to protect various light hazard area coverages and should be installed in accordance with NFPA 13. This sprinkler series is available in four temperature ratings and several finishes to meet many varying design requirements.
The heart of Globe's GL Series sprinkler proven actuating assembly is a hermetically sealed frangible glass ampule that contains a precisely measured amount of fluid. When heat is absorbed, the liquid within the bulb expands increasing the internal pressure. At the prescribed 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.
