About this detail

The fire sprinkler service entry begins with supply piping connecting through a reduced pressure backflow preventer assembly, with Division 15300 work beginning at the flange. Control valves equipped with tamper switches wire directly to the fire alarm panel by the fire protection contractor. An inspector's test loop featuring a sight glass branches off the main line, while a main drain pipes to a service sink, floor drain, or floor sink. A ball drip is included as required and piped full size to the building exterior with a finish matching the fire department connection.
