The Model RC-QR sprinklers are listed by UL and C-UL as quick response / standard coverage for use in accordance
with NFPA.
Also the Model RC-QR is FM Approved as a Standard Response for Non-Corrosive Atmospheres. The herein stated rules
for use and installation of the Model RC-QR are provided by the manufacturer and must be strictly implemented for safe
and full results.

Notes
Fire Sprinkler Systems should only be designed and installed by individuals who are completely familiar with automatic
sprinkler system design, installation procedures, and techniques.
Several criteria may apply to the installation and usage of each sprinkler. Consequently, it is recommended that the sprinkler
system designer review and develop a working understanding of the complete list of criteria prior to initiating the design of the
sprinkler system.
Questions concerning sprinkler installation and usage criteria, which are not covered by the following instructions, should be
submitted to your contracted company. Include sketches and technical details, as appropriate.
In some instances, the requirements of this document may concern specifications which are more stringent, and which take
precedence over those specified in NFPA 13 or by the authority having jurisdiction.
The Model RC-QR must not be used in applications where the air pressure above the ceiling is greater than that below.
Inspect all sprinklers after installation to ensure that both the gap between the cover plate, ceiling and the 6 slots in the cup
are open and free from any air flow impediment.
The spray from the sprinkler is distributed radially outward and downward from the sprinkler deflector. Consequently, the
sprinklers must be located such that there will be no blind spaces shielded from spray by partitions, room dividers, overhangs
or other parts of the dwelling structure.
The number of sprinklers within each compartment (as defined by NFPA 13) must be kept as few as possible while observing
all guidelines relating to obstructions and spacing.
Use only the Cover Plate provided for the Model RC-QR. The sprinkler must be secured in place by firmly fastening the
sprinkler system piping to the structure. If the sprinkler is not properly secured in position, reaction forces resulting from
sprinkler operation could alter its orientation and its water distribution pattern.
