Fire Sprinkler Systems Acceptance:
On the permit issued to the applicant and contractor there may be several fire protection system inspections. Pertinent to fire sprinklers are Fire Sprinkler Rough-In #608, Fire Sprinkler Pressure Test #604, Fire Sprinkler System Final #606. All system tests and inspections are to be called in by the contractor to the Development Services IVR inspection hotline. The phone number is 785-832-7710. Follow the automated hotline to completion. The contractor should leave contact information as to schedule all personnel needed to complete this inspection. The Fire Prevention Division will contact the contractor the morning of inspection to coordinate acceptance testing. If the contractor wishes to perform testing in the morning it is recommended to contact Fire Prevention Division (785-830-7003, 832-3174 or 832-3175) at least 24-48 hours prior to inspection date.
- Fire Sprinkler Rough-In #608 is scheduled after piping installation is complete, preferably prior to application of building finish application. All areas of protected buildings are inspected to ensure adequate fire sprinkler coverage. Additional coverage may be required if field inspections reveal unanticipated deficiencies.
- Fire Sprinkler Pressure Test #604 Acceptance tests shall be performed in accordance with NFPA 13 chapter 24, Systems Acceptance. The Fire Sprinkler Pressure Test #604 is the hydrostatic test of the aboveground system. The system is required to hold >200 psi for 2 hours.
- Fire Sprinkler System Final #606 is the final step in the acceptance testing of Fire Sprinkler Systems. Usually, this test is coordinated along with the Fire Alarm Final and Fire Department Final. The Fire Sprinkler Final evaluates the interface of the sprinkler and fire alarm. Valves, flow switches and electronic components are evaluated. The Contractor’s Material and Test Certificate for Aboveground Piping shall be submitted at the completion of testing.
All Fire Protection systems shall be approved on the permit prior to any approval for Temporary Certificate of Occupancy or Certificate of Occupancy recommendation to the Development Services Building Official.
