QRFS zeroes in on two terms describing one of the most common fixtures in fire protection—pendent sprinkler and pendant sprinkler—explaining why many manufacturers favor one over the other (even if consumers don't).
Wet sprinkler systems may dominate the fire safety market, but there’s a better solution for certain environments prone to freezing: dry sprinkler systems. QRFS explains how dry systems work, providing the coverage you need without the fear of burst pipes.
Working pressure gauges make it easy to spot serious problems in a fire sprinkler system. QRFS looks at the NFPA requirements for fire sprinkler gauge placement and replacement in residential and commercial systems.
Dry, preaction, and deluge sprinkler systems have unique equipment that needs to be checked so the system functions properly. QRFS’ continuing series on commercial fire sprinkler inspections looks at the NFPA inspection requirements for automatic detection systems and air compressors.
Tanks are often required as the sole water source for fire sprinkler systems in rural areas, and can serve as a secondary source for structures that have a high water demand. QRFS’ continuing series on commercial fire sprinkler inspections looks at the NFPA requirements for inspecting tanks.
NFPA and numerous fire sprinkler manufacturers have a zero-tolerance policy for any sprinkler that has been painted with any amount of aftermarket paint. Replacing painted fire sprinklers is the proper course of action. QRFS looks at why the rules are so strict, as well as how to choose a replacement model.
Regular inspections are required to keep commercial fire sprinkler systems working and up to code. In the first part of this series, QRFS explains the steps involved in the annual visual inspection of fire sprinkler heads.
CPVC and PEX have become extremely popular, safety-approved pipe materials in home fire sprinkler systems. Both are easier and less expensive to install than metallic pipe and have better performance characteristics. But which of the two thermoplastics is better? QRFS attempts to answer this excellent question.
Tamper-resistant fire sprinklers are essential in prisons, jails, mental health facilities, and other secured environments. QRFS explains how institutional fire sprinkler heads can help prevent vandalism, suicide, accidental discharges and other incidents that involve tampering with an automatic fire safety system.
Cleanrooms that are used in manufacturing, research, and medical facilities require fire sprinkler systems that are easy to clean without damaging the sprinkler heads. QRFS details the benefits of fire sprinkler cover plates in cleanrooms and other highly-sanitary environments.
