GLOBE 4906 CONCEALED HEADS.pdfGIrmb FIRE SPRINKLER CORPORATION THE INCH® RESIDENTIAL AUTOMATIC SPRINKLERS GL4906 ONE INCH ADJUSTABLE FLAT PLATE CONCEALED PENDENT DESCRIPTION AND OPERATION The Globe GL4906 Residential One Inch Adjustable Concealed Pendent Sprinkler has a flat plate profile that utilizes a 3mm frangible glass ampule as the thermosensitive element. It features economy, aesthetics and the lowest allowable water flow with a nominal 1" of adjustment for easier installation. The combination of the 3mm frangible glass ampule and specially designed deflector make the GL4906 the ultimate in life safety and fire control. It has met the strict requirements of Underwriters Laboratories Inc. as described in UL Standard, 1626, for Residential Sprinklers for Fire Protection Service, and should be used accordingly. This sprinkler should also be installed in accordance with the appropriate NFPA Stan- dard 13, 13D or 13R and under the direction of the approving authorities having jurisdiction. All that is seen at the ceiling is the 3 5/16" diameter flat ceiling plate color finished to match the speci- fier's exact requirements. 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 residential pendent spray sprinkler. At the prescribed temperature the internal pressure within the ampule exceeds the strength of the glass causing the glass bulb to shatter. This results in water discharge which is distrib- uted in an approved pattern.
