FM Approves this sprinkler as a standard responseconcealed sprinkler intended for use in accordance with FMLoss Prevention Data Sheet 2-8N.Product DescriptionThe Reliable Model G4A Concealer ® uses a proven quick responsefusible element in a standard style sprinkler frame with adrop-down deflector. This assembly is recessed into the ceilingand concealed by a flat cover plate assembly. The threadedengagement provides ½ (13mm) of cover adjustment. The flatcover plate is attached to the skirt using either 135°F (57C) or165F(74C) ordinary temperature classification solder.When the ceiling temperature rises, the solder holding the flatcover plate melts, the flat cover plate released thus exposingthe sprinkler inside to the rising ambient temperature.The subsequent fusing of the element opens the waterwayand causes the deflector to distribute the water. Any secureengagement between the cover plate and cup will assure thatthe drop-down deflector is properly located below the ceiling.The Reliable Automatic Sprinkler Co., Inc. , 103 Fairview Park Drive, Elmsford, New York 10523
