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.

Valves are an essential component on any fire protection system, and automatic sprinkler systems are no exception. QRFS reviews the inspection requirements for fire sprinkler valves outlined in NFPA 25, along with explanations of what these parts do.

In QRFS’ continuing series on NFPA’s commercial fire sprinkler inspection requirements, we look at what you need to check out — and when — it comes to fire sprinkler gauges, signs, water flow alarms and supervisory signaling devices.

Fire pumps add a great deal of complexity to the maintenance of a commercial fire sprinkler system. In Part 3 of QRFS’ continuing series, we explain the inspection requirements for systems with fire pumps — whether they use electric, diesel, or steam-turbine engines.

Regular inspections are required to keep commercial fire sprinkler systems working and up to code. In the second installment of a series, QRFS explains the steps involved in the annual visual inspection of fire sprinkler pipe and fittings, plus how to classify any issues that are found.

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.
