A-73 High Pressure Model GL5657 Adjustable Concealed Pendent
High Pressure Model GL Series Adjustable Concealed Pendent
Description and Operation
The Globe High Pressure Model GL Series Concealed Pendent Sprinkler offers the ultimate in low profile, aesthetically pleasing appearance. It is available with 1/2" of adjustment, and may be used in areas where flowing and static pressure do not exceed 300 psi. Globe's Concealed Sprinkler utilizes its frangible glass ampule type sprinkler which is located above the ceiling and concealed from view by the ceiling plate. The plate is soldered to the sprinkler special upper support assembly in three places. Upon the application of sufficient heat, the plate falls to the floor exposing the pendent spray sprinkler. At the ampule's rated temperature, the sprinkler opens discharging water onto the floor in its required and approved distribution pattern.
