Fire Safety: Types of Residential Sprinkler Systems
The National Fire Protection Association (NFPA) 13D Standard for the design and installation of residential sprinkler systems identifies two basic types of systems — multipurpose and standalone.
Multipurpose systems integrate the fire sprinklers with the cold-water plumbing lines in the house, so the sprinklers perform just like any other plumbing fixture. These systems were created specifically for residential use, and are designed to be easily and seamlessly incorporated into a home’s construction process.
Standalone residential sprinkler systems use a separate, additional system of piping that must be kept isolated from the home’s drinking water supply by a backflow preventer. This component adds additional cost to the initial installation as well as annual maintenance costs which can significantly add up over time.
