DESCRIPTION AND OPERATION

The Globe GL Series Sprinkler is a low profile yet durable

design which utilizes a frangible glass ampule as the thermo-

sensitive element. While the sprinkler provides an aestheti-

cally pleasing appearance, it can be installed wherever stan-

dard spray sprinklers are specified. This sprinkler series is

available in various styles, orifices, 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.
