Drawings: 1. Fire Protection Drawings show general arrangement of piping. Follow as closely as actual building construction and work of other trades will permit. 2. Consider Architectural and Structural Drawings part of this work insofar as these drawings furnish information relating to design and construction of building. These drawings take precedence over Fire Protection Drawings. 3. Because of small scale of Drawings, it is not possible to indicate all offsets, fittings, and accessories that may be required. Investigate structural and finish conditions affecting this work and arrange work accordingly, providing such fittings, valves, and accessories required to meet conditions. 3.2 INSTALLATION A. Install system in accordance with NFPA / ANSI 13, Ordinary 1 Hazard B. Connect system to flange provided under Section C. Install system to drain. Drain trapped piping in accordance with NFPA / ANSI 13, Paragraphs and Install main drain from riser. 2. Install auxiliary drains in low points of piping system and inspector's test valve drain to mechanical pad located outside building, unless directed otherwise by Architect. D. Install piping system so it will not fail due to freezing temperatures. E. Do not use dropped, damaged, or used sprinkler heads. F. Pendants: 1. Do not use regular pendants. 2. Install dry pendants with tees and not elbows. Do not adjust length with pipe nipples and couplings Section Hickory Flat, Canton Wards June 10, 2009 (Rev) Dry-Pipe Sprinkler Systems

19 3. Individually measure and order each dry pendant based on measured distance from ceiling to face of branch line tee. G. Minimum slope of branch lines is 1/2 inch per 10 feet 12 mm in 3 meters. Minimum slope of main lines is 1/4 inch per 10 feet 6 mm in 3 meters. H. Install sprinkler lines concealed. I. Install tamper switches and pressure flow detectors where located by Architect. J.Install automatic ball drip device in lowest point of piping to the fire department connection and drain to exterior of building. K. Brace and support system to meet seismic zone requirements for building site. 3.3 FIELD QUALITY CONTROL A. Site Tests: 1. Test system according to 'Contractor's Material & Testing Certificate for Above Ground Piping' NFPA-13, figure Tests shall be witnessed by Architect and by representative of local jurisdiction having authority for fire prevention. 3. Test blanks shall have red painted lugs protruding beyond flange to clearly indicate their presence and be numbered to assure their removal when testing is completed.
