The Model RC-QR Commercial Flat Concealed Sprinklers are automatic sprinklers of the compressed fusible solder type.
They are decorative and quick responding. The Cover Plate Assembly hides the Deflector, Heat Responsive Element
etc., which is concealed above the ceiling. The cover plate has a flat profile, and its diameter is extremely small (2-5/8
inch, 68mm). The push-on and/or thread-on, thread-off design of the concealed cover plate assembly allows for easy
installation of the cover plate.
Therefore, the Model RC-QR should be your first choice when aesthetics is the major consideration for ultimate appeal
and unbeatable performance is desired.
They are to be installed per NFPA 13 guidelines.
The Model RC-QR has a 5.6 (80.6 LPM/bar
1/2
) K-factor.
For extended installation flexibility, the Model RC-QR provides 1/2 inch (12.8mm) 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 RC-QR allows for an increased chance of occupants to escape
or evacuate in case of a fire. However, fire sprinkler systems are not a substitute for fire safety awareness or fire safety
construction required by building codes.
