Product Description The Reliable Model G5-56 and G5-42 uses a proven quick response fusible element in a standard style sprinkler frame with a drop-down deflector. This assembly is recessed into the ceiling and concealed by a flat cover plate assembly. The threaded engagement provides ¾” (19mm) of cover adjust- ment. The flat cover plate is attached to the skirt using either 135°F (57°C) or 165°F (74°C) ordinary temperature classifica- tion solder. When the ceiling temperature rises, the solder holding the flat cover plate melts, the flat cover plate released thus expos- ing the sprinkler inside to the rising ambient temperature. The subsequent fusing of the element opens the waterway and causes the deflector to distribute the water. Any secure engagement between the cover plate and cup will assure that the drop-down deflector is properly located below the ceiling. Application The Reliable Model G5-56 and G5-42 are the most versatile quick response concealed sprinklers available. It provides the best form of fire protection while offering an attractive ap- pearance and 3/4” (19mm) of cover adjustment for ease of installation.

The Model G5-56 and G5-42 are designed for use where aesthetic appearance is important. Offices, hospitals, motels and restaurants are but a few of the applications where it can be used. The Model G5-56 and G5-42 is a UL Listed Quick Response Concealed sprinklers intended for use in accordance with NFPA 13. FM Approves the G5-56 sprinkler as a standard re- sponse concealed sprinkler intended for use in accordance with FM Loss Prevention Data Sheet 2.0. Plain Cover Plate Perforated Cover Plate Installation Do not install the G5-56 and G5-42 in ceilings which have positive pressure in the space above. • Cut a 25/8” inch (67mm) diameter hole is cut in the ceiling, the sprinkler is easily installed with the Model FC Wrench. The wrench has a socket drive which is inserted into the body of the sprinkler. When installing a sprinkler the wrench is first positioned into the sprinkler/cup assembly until the wrench socket engages the body of the sprinkler. The sprinkler is then tightened into the pipe fitting. When inserting or remov- ing the wrench from the sprinkler/cup assembly, care should be taken to prevent damage to the sprinkler. DO NOT WRENCH ON ANY OTHER PART OF THE SPRINKLER/ CUP ASSEMBLY. Install the cover plate by hand turning the cover in the clockwise direction until it is tight against the ceil- ing. A protective cap is provided to protect the drop-down sprinkler deflector from damage which could occur during construction before the cover plate is installed. The cap is factory installed inside the sprinkler cup. Remove cap to install sprinkler, then re- install cap until the cover plate is installed. Maintenance The Model G5-56 and G5-42 should be inspected quarterly and the sprinkler system maintained in accordance with NFPA 25. Do not clean sprinklers with soap and water, ammonia or any other cleaning fluids. Remove any sprinkler that has been painted (other than factory applied) or damaged in any way. A stock of spare sprinklers should be maintained to allow quick re- placement of damaged or operated sprinklers. Prior to installa- tion, sprinklers should be maintained in the original cartons and packaging to minimize the potential for damage to sprinklers that would cause improper operation or non-operation.
