It offers the ultimate in low profile, aesthetically pleasing appearance. All that is seen at the ceiling is a 3 5/16"diameter ceiling plate color finished to match the specifier's exact requirements. The GL Series Dry Concealed Sprinkler may be virtually invisible as it does not interrupt the"smooth flow" of the ceiling. Globe's Dry Concealed Sprinkler utilizes its frangible 5mm glass bulb 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 releasing the bulb seat, causing the inner tube assembly to move allowing the 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. A special spring is attached to the pendent deflector that serves to provide a constant tension against the ceiling , plate. This feature virtually ensures freedom from environmental vibration problems. 'I The heart of Globe's GL Series sprinkler proven actuation 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.
