Review the confirmed product information, including description, features, benefits, and applications.
AG Standard Coverage Concealed Pendent Sprinklers from AG Fire Sprinkler provide discreet fire protection with minimal visual impact in finished interiors. The AGC-56 sprinkler is recessed into the ceiling and hidden by a small-diameter flat cover plate that blends into the ceiling.
When the ceiling temperature rises, the solder holding the cover plate melts and the plate drops away, exposing the sprinkler to the rising temperature. The drop-down deflector then distributes the water. The AGC-56 is listed as quick response under UL and as standard response under FM.
The sprinkler has a K80 (5.6) orifice, a 1/2" NPT connection and a maximum working pressure of 175 psi (12.1 bar), with 3/4" (19 mm) of cover adjustment for easier installation.
