City of Pearland Sprinkler Requirements

1. The Fire Dept. Connection (FDC) needs to be remote from the building, street side and easily accessible along a fire apparatus access road. 2. The FDC cannot be attached to the building; it needs to be out of the collapse zone of the structure. If the building is 30 feet in height, the connection needs to be at least 31 feet away. The FDC has to be within 100’ of a fire hydrant. 3. The FDC will need a 5” Storz connection instead of the typical 2 ½” Siamese connection. The Storz connection needs to be at a 30-degree angle to the ground with a Knox locking cap installed. The FDC needs to be at least 18 inches in height and not more than 4 feet in height. If NFPA 13R 2 ½ with Knox locking cap is required. 4. The FDC cannot be on the fire line, it will need to be a separate dry line to the riser. A Post Indicator Valve (PIV) is required on the sprinkler fire line as close to the tap as possible as long as the PIV is not located in the 10 foot Public easement. The PIV will need to have a tamper switch for alarm monitoring. No other water line taps are allowed off the fire sprinkler fire line. The City requires a double check back flow preventer inside the building on the sprinkler riser before the FDC tap. This will not be allowed in a vault. 5. Separate sprinkler plans need to be submitted to the Fire Marshal’s Office by the licensed fire sprinkler installer for review. The sprinkler plans will require a third party review by ISO for hydraulic calculations, checked and stamped on the plans from ISO prior to submittal to the City. ISO will need to see underground drawings with aboveground drawings. Underground will need to be installed by a licensed fire sprinkler underground contractor. A copy of the license and insurance in the name of the City of Pearland shall be provided with submittal. Two sets of drawings are required; one set should be on a PDF file due to plan storage limitations. If possible all documents including cut sheets should be on the PDF file. Once approved, the Permit Office will issue a permit. 6. Sprinkler systems will need to be designed with a 10% safety factor to accomplish long-term system effectiveness. 7. All hydrostatic testing, inspection, and flushing of all fire line piping shall be witnessed by a representative from the Fire Marshal’s Office prior to covering any joints, bends, and thrust blocks.
