Flashover is a very dangerous condition that could result in loss of life if allowed to occur. Flashover occurs in fires where everything in a room is consumed by fire. First, the 13d-based sprinkler system, which is designed to prevent flashover. The intent statement gives many keys to success of the system. The layout, calculation and installation of systems installed in accordance with this standard shall only be performed by people knowledgeable and trained in such systems.
A sprinkler system designed and installed in accordance with this standard shall be expected to prevent flashover (total involvement) in the room of fire origin, where sprinklered, and to improve the chance for occupants to escape or be evacuated. The purpose of this standard shall be to provide a sprinkler system that aids in the detection and control of residential fires and thus provides improved protection against injury, life loss, and property damage. It is critical to remember the intent of NFPA 13d (NFPA 13d 1.2): These systems allow a separate design with separate piping.
This standard provides the basis for the installation of all residential sprinklers in homes and the standalone system utilizes separate piping from the plumbing system. As related to residential sprinklers in new homes, the standard is set by NFPA 13d: The Standard for the Installation of Sprinklers in One and Two Family Dwellings and Manufactured Homes sets the standard. There are hundreds of documents that cover fire suppression, fire alarm systems, or fire doors.

In Part I of this three-part series we reviewed the basics of residential sprinkler systems with a focus on the standalone sprinkler system based on the National Fire Protection Association (NFPA) 13d standard.
