These devices are used to shut portions of the fire sprinkler system off for maintenance or repair work without taking the entire system offline, endangering building occupants in case of fire. While not required in all circumstances, they should be considered as another fire safety mechanism.

The UNITED Fire Systems Riser-Mount Air Compressor Model RMAC-LP is a device that automatically provides compressed air for preaction fire sprinkler and dry-pipe fire sprinkler systems.

Design criteria for storage fire protection systems must consider a substantial number of variables: what is being stored and how, the height of the planned storage, how high the ceiling is above the storage, and what the water supply is.

As the built and to-be-built environments increase in complexity, speed and efficiency, fire protection professionals must work together to protect people, property and the environment. A professional panel discusses this issue and other challenges when working on projects with delegated design clauses. 

How fire sprinkler piping is arranged affects the system through water flow changes, system calculations and components used. Installation requirements for any sprinkler system can be found in NFPA 13, Standard for the Installation of Sprinkler Systems. 

Like a building’s water distribution system, fire sprinkler system piping can freeze in frigid temperatures and cause major damage. The checklist provided here can assist building owners or qualified technicians to properly winterize this life-safety system before the onset of cold weather. 

Current codes call for the installation of fire sprinklers in many instances in new construction, but there are still many cases where sprinklers are not required. 

Creating our building codes includes much research and documents from subject matter experts across the building industries. It is important to learn how these different standards affect each other. Read on to discover how the new earthquake protection codes can impact water-based fire protection systems.

More than two decades ago, NFPA 13 required alpha-numeric markings on all fire sprinklers. Read on to learn the history of these markings, called sprinkler identification numbers, and how they are used today.  

The 2022 edition of NFPA 25 modified the formula to determine the capacity of the fuel storage tank for diesel-driven fire pump systems. Read on to discover the rationale behind the technical committee’s actions.
