Pumps for Residential and Domestic Fire Sprinkler Systems
Fire sprinkler protection is required for most new residential buildings and fire sprinkler protection makes sense for all residential building, whether the protection is required under the state fire code or not. NFPA 13R is the Standard for the Installation of Sprinkler Systems in Residential Occupancies up to and Including Four Stories in Height and NFPA 13D is the Standard for the Installation of Sprinkler Systems in One-Two Family Dwellings and Manufactured Homes. These fire sprinkler systems are designed to be more focused on life safety and use less water than standard fire sprinkler systems. This means the residential and domestic fire sprinkler systems cost less to install. In rural applications where a pump is needed for the water supply of a 13D or 13R fire sprinkler system there can also be savings by using a pump with a limited service controller. A limited service controller can be used with a single-phase electrical power supply and there are fewer regulations regarding the installation. Any controller is still required to meet the power source requirements of NFPA 70: 695.3. More specific requirements for the installation of a limited service controller are covered in NFPA 20: 7-7. Limited service controllers are permitted for any 13D or 13R fire sprinkler system.
