A-44 Extended Coverage Light Hazard Horizontal Sidewall Sprinkler - GL5628
Extended Coverage Automatic Sprinklers Model GL5628 Horizontal Sidewall
The Globe Quick Response Model GL5628 Extended Coverage Horizontal Sidewall Sprinkler is a low profile yet durable design which utilizes a 3mm frangible glass ampule as the thermosensitive element. This provides sprinkler operation approximately six times faster than ordinary sprinklers. While these Quick Response Sprinklers provide an aesthetically pleasing appearance, they can be installed wherever standard extended coverage horizontal sprinklers are specified; but offer the additional feature of greatly increased safety to life. Quick Response Sprinklers should be used advisedly and under the direction of approving authorities having jurisdiction, in accordance with their listings and in accordance with NFPA 13.
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. 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.
