Provide and locate junction boxes as required to provide a functional raceway system in compliance with the Specifications and the NEC.

3. All security electronics system circuits shall be installed in conduit with the following exceptions:

a. Wire Ways (fully enclosed): Class1, Class 2, Class 3, and Optic Fiber Cable circuits may be installed in wire ways (fully enclosed) within the secure electronics equipment rooms where allowed by the National Electrical Code.

1) Optical Fiber Cable circuits installed within a wire way shall also be installed within innerduct specified in Section 28 51 20 – Security Electronics Fiber Optic Cable System to ensure protection from physical damage.

b. Cable Tray (ladder type): Class 2, Class 3, and Optical Fiber Cable circuits may be installed in cable tray (ladder type) within the secure electronics equipment rooms where allowed by the National Electrical Code. Cables installed in cable tray (ladder type) shall be of the type listed for that application.
