Fire Suppression Submittal Requirements

Automatic Fire Suppression Systems Plan Review Submittal Requirements

The NC Fire Prevention Code requires that a construction permit be obtained for the installation of/or modification to automatic fire suppression systems. The code also requires that construction documents be submitted for review and approval prior to system installation. These systems are normally used for the protection of cooking equipment, ventilation and exhaust systems, spray booths, electrical rooms, and areas where an alternative to a required automatic sprinkler system is allowed and approved.

The following information and construction documents are required to be provided with the Fire Department Construction Permit Application for a fire suppression system. Not every project will require the same amount of information, however, the more information that is provided with the plans, the less likelihood that additional information will be needed for the plan review process or the need for modifications being identified during the inspection process. Some jobs, such as modifications or alterations to an existing system, may not require all of the following information. If some of the information is not needed, it is important that you call and discuss the circumstances before submitting the Fire Department Construction Permit Application.
