The system includes a suitable water supply, such as a gravity tank, fire pump, reservoir or pressure tank or connection beginning at the supply side of an approved gate valve located where the pipe or piping system provides water used exclusively for fire protection and related appurtenances and to standpipes connected to automatic sprinkler systems. The portion of the sprinkler system above ground is a network of specially sized or hydraulically designed piping installed in a building, structure or area, generally overhead, and to which sprinklers are connected in a systematic pattern. The system includes a controlling valve and a device for actuating an alarm when the system is in operation. The system is usually activated by heat from a fire and discharges water over the fire area.
Work can start when the permit is issued.
The contractor calls for an inspection with one day advance notice. In addition of new inspections, we make periodic sprinkler inspections and test inspections. NFPA 25 is the standard for the inspection, testing and maintenance of water - based fire protection systems.
