Check out or Water Flow and Backflow Prevention page for more information on these device requirements.

Fire Pump Requirements

When sprinkler requirements dictate the need for a fire pump, the installation must comply with the following standard:

  • National Fire Prevention Association (NFPA) No. 20: Installation of Stationary Fire Pumps

Fire Department Connection Requirements

When required, based upon the type of system installed, the fire department connection shall consist of:

  • A single 5 inch Storz fitting and chained cap.
  • All associated piping must be sized to hydraulically supply the designed flow requirements at 100 psi or less inlet pressure

System Monitoring Requirements

All fire sprinkler systems (except for attached single family homes, townhouses, detached single family homes, and pre-manufactured single family homes) are required by local ordinance to be monitored 24 hours a day by an appropriate alarm monitoring service. The following pieces of equipment are required to be monitored:

  • Isolation Valves (i.e., OS and Ys)
  • Fire Pump (if applicable)
  • Flow Switch
All monitoring equipment must comply with NFPA No. 72: National Fire Alarm Code

Requirements for Certificate of Occupancy (Fire Sprinkler System Only)

The following fire sprinkler system requirements must be completed in order to obtain a Certificate of Occupancy:
  1. All system components are installed according to the approved plans and hydraulic calculations.
  2. The entire system is hydrostatically tested at 200 psi for 2 or more hours.
  3. Underground piping is pressure tested, chlorinated, and flushed in accordance with Public Works/Engineering Department criteria.
  4. Fire pump (if applicable) if flow tested and meets design criteria.
  5. Alarm devices are installed and connected to a central station alarm monitoring facility.
