A-94 Dry Type Vertical Sidewall Sprinkler

GL Series Dry Type Vertical Sidewall Upright & Pendent

The Globe GL Series Dry Type Vertical Sidewall Sprinkler is designed for use in special applications such as freezing environments and conditions where sediment or foreign materials might accumulate in ordinary drop nipples.

The Globe GL Series Dry Type Vertical Sidewall Sprinkler utilizes a frangible glass ampule sprinkler. At the ampule's rated temperature, the sprinkler opens releasing the bulb seat, causing the inner tube assembly to move, allowing spring assembly to pivot alongside the inner tube. At this time, water flows through the sprinkler and is distributed by the deflector, in an approved discharge pattern.

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.

Globe GL Series Dry Vertical sprinklers should be installed in accordance with the requirements set forth in NFPA 13. These sprinklers are to be installed using a pipe wrench applied to the outer tube. When this is not possible, the proper sprinkler head wrench may be used with extreme care for lengths up to approximately 18". Excessive force may distort the frame thus destroying the unit.

The GL Series Dry Sprinkler must not be installed in a short radius 90° elbow. When installing in other than an iron tee, the clearances between the end of the sprinkler and fitting should be checked.

When installed in a wet system extending into a freezing area, see chart on Dry Caution Sheet for minimum exposed barrel length to prevent ice plugs.  Please refer to our Dry Caution Sheet for further important installation data.
