Description and Operation
The Globe GL Series10mm Sprinkler is a low profile yet durable design which utilizes a frangible glass ampule as the thermosensitive element. While the10mm sprinkler provides an aesthetically pleasing appearance, it can be installed wherever standard spray sprinklers are specified. This sprinkler series is available in various styles, temperature ratings and finishes to meet 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, depending upon the deflector style used.
The sprinkler and escutcheon are not factory assembled. Assembly is done in the field.
