RD105 Commercial Flat Concealed Pendent Sprinkler

The Model RD105 Commercial Flat Concealed Sprinklers are automatic sprinklers of the compressed fusible solder type. These are decorative and quick/standard response. The frame of the sprinkler hides the deflector, gasket, etc., which is in turn concealed above the ceiling by the cover plate assembly. The cover plate has a flat profile, and its diameter is extremely small at 60cm diameter.  The push-on/thread-on, thread-off design of the concealed cover plate assembly allows easy installation of the cover plate. Therefore, the Model RD105 should be your first choice when aesthetics is the major consideration for ultimate appeal and unbeatable performance is desired.

They are to be used in wet pipe sprinkler systems per NFPA 13 or as required by the authority having jurisdiction.

The Model RD105 has a 5.6 (80) K-factor. For extended installation flexibility, the Model RD105 provides 3/8 inch (9.0mm) vertical adjustment. This adjustment in installation decreases the need for precise cutting of the pipe that drops to the sprinkler and allows for a perfect fit with a range of pipe lengths. The heat sensitivity and water distribution design of Model RD105 allows for an increased chance of occupants’ escape or evacuation in case of fire. However, fire sprinkler systems are not a substitute for fire safety awareness or fire safety construction required by building codes.

Ease of Installation Due to the protective cap’s innovative design elements.
• The unique protective cap allows for the head to be installed without removing the cap, giving protection to head during the entire installation
• The tolerance limit to the ceiling level is clearly marked on the protective cap and small bumps are added to the head so it can be fastened with just the right tension.
• Installable with Cap on
• Cap has a custom opening for the socket to enabling seamless installation

Saves Time
• Saves two steps of removing and later reinserting the cap multiplied by the total number of sprinkler heads on the job.
• No more time spent tediously reinforcing protective caps to the heads with tape.
• No more time and money wasted on returning to a job site to secure flimsy caps if they have fallen off.
• Less time, less labour, and less room for error equals more profit for the contractor.

Safety Feature
• Rapidrop Sprinkler heads also provide a safety feature as the sprinkler’s deflector and delicate inner components are protected from the moment they are packaged at our manufacturing facility to when they are ready to be installed.
