A. "Approved" refers to the approval of the Tukwila Fire Department.
B. "Automatic sprinkler system" is an integrated system of underground and overhead piping designed
in accordance with fire protection engineering standards. The installation includes one or more automatic
water supplies. The portion of the sprinkler system aboveground is a network of specially sized or
hydraulically designed piping installed in a building, structure or area, generally overhead, and to which
sprinklers are attached in a systematic pattern. The valve controlling each system riser is located in the system
riser or its supply piping. Each sprinkler system riser includes 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.
