Residential fire sprinkler systems

FIREPEXTM residential fire sprinkler system is designed to prevent flashover (total involvement of the fire) in the room of fire origin, where sprinklered, and to improve the chance for occupants to escape or be evacuated.  FIREPEX fittings and RAUPEX® UV Shield pipe can be used to install these systems, sometimes in conjunction with plumbing systems. REHAU FIREPEX residential fire sprinkler system serves the requirements for fire sprinkler systems as defined by National Fire Protection Association (NFPA) Standard 13D Installation of Sprinkler Systems in One- and Two- Family Dwellings and Manufactured Homes and the International Residential Code Section (IRC) P2904.

Key benefits

How it works

When the heat from a fire activates a fire sprinkler, pressurized water from the piping system is discharged.

Combining the flexibility of RAUPEX pipe and the security of EVERLOC+ fitting technology, our FIREPEX residential fire sprinkler system has all the same benefits as our installer-friendly PEXa plumbing system. The unique flexibility of PEXa pipe reduces the number of joints required compared to rigid piping systems, while also enabling the use of compression-sleeve fittings that provide superior flow and security compared to insert fittings. In addition, the FIREPEX fittings have an integrated mounting bracket that speeds installation.

FIREPEX is solely for use in fire sprinkler systems as defined by NFPA 13D and IRC P2904.

REHAU pipe and fittings are to be installed in accordance with this standard and the manufacturer’s recommendations. 

Installation

Passive purge sprinkler system

Stand-alone sprinkler system

In a stand-alone system, as defined in NFPA 13D, the above ground piping serves only fire sprinklers.

Stand-alone



Multipurpose sprinkler systems

Multipurpose systems are defined in NFPA 13D and P2904 as a piping system intended to serve both fire sprinklers and domestic plumbing needs.

A multipurpose system integrates the piping connected to a water supply with sprinklers that automatically discharge water over a fire area.

All piping in a multipurpose system supplying sprinklers must be listed or conform to the piping specifications in NFPA 13D or IRC P2904.
