Concealed Fire Sprinkler
The reliable concealed sprinkler 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 flat cover plate is attached to the skirt using either 135°F (57°C) or 165°F (74°C) ordinary temperature classification solder. When the ceiling temperature rises, the solder holding the flat cover plate melts, the flat cover plate released thus exposing 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 concealed sprinkler is usally installed at places with luxurious decoration and need beautiful appearance such as antechamber, meeting room, shopping mall, hotel and recreational centre, etc. It can be concealed in ceiling completely. The color of cover plate can match with ceiling to make the hole hue harmonious.
