A-3 Automatic Sprinklers Model GL3010
Automatic Spinklers Model GL3010 Pendent Recessed Pendent
Description and Operation
The Globe Model GL3010 Residential Sprinkler has a low profile yet durable design, which utilizes a 3mm frangible glass ampule as the thermosensitive element. It features economy, aesthetics and low flow.
The combination of the 3mm frangible glass ampule and specially designed deflector makes the Model GL3010 Residential Sprinkler the ultimate in life safety and fire control. This Globe Pendent and Recessed Pendent Residential Sprinkler has met the strict requirements of Underwriters Laboratories Inc. as described in the UL Standard for Residential Sprinklers for Fire Protection Service, UL 1626, and should be used accordingly. This sprinkler should also be installed in accordance with the appropriate NFPA Standard 13, 13D or 13R and under the direction of the approving authorities having jurisdiction.
The heart of Globe's Model GL3010 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.
