Residential Concealed Sprinkler Heads

Globe's residential concealed sprinkler head utilizes it's 3mm frangible glass ampule as the thermosensitive element.  These sprinkler heads are typically located above the ceiling and concealed from view by the ceiling plate. The ceiling plate is soldered to the sprinkler's special upper support assembly in three places. Upon the application of sufficient heat, the plate falls to the floor exposing the quick response pendent spray sprinkler. At the ampule's rated temperature, the sprinkler opens discharging water onto the floor in its required and approved distribution pattern.
