D.	Install system to drain. Drain trapped piping in accordance with NFPA 13, Paragraph 4-
5.3.1.

1.	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 otherwise directed by Architect.

E.	Install piping system so it will not be exposed to freezing temperatures.

F.	Do not use dropped, damaged, or used sprinkler heads.

G.	Install sprinkler lines concealed.

H.	Install tamper switches and pressure flow detectors where located by Architect.

I.	Install water powered motor gong on exterior wall in accordance with Manufacturer's instructions.

J.	Brace and support system to meet seismic zone requirements for building site.

3.3	FIELD QUALITY CONTROL
