H. Splices, Taps, and Terminations: Make splices, taps and terminations on numbered
terminal punch blocks in junction, pull, and outlet boxes, terminal cabinets and equipment
enclosures. All splices shall be labeled at each termination point with the station or room
designation. Provide a laminated terminal block schedule for the 66-blocks in the terminal
cabinet behind the intercom rack. Mount schedule on inside of cabinet door.
I. Identification of Conductors and Cables: As specified in Section 16075.
J. Weatherproofing: Provide weatherproof enclosures for items to be mounted outdoors or
exposed to weather.
K. Remote Access: Coordinate with ASD to obtain an IP address for remote access to the
intercom system via the device server and ASD WAN connection.
L. Speaker Taps: Coordinate with ASD Project Manager for exact tap settings of all
speakers.
3.3 CABLE INSTALLATION
A. Follow cable manufacturer’s specification regarding handling methods, retaining/support
methods, bending radius and maximum pulling tension limitations. Where manufacturer
does not provide bending radius information, minimum bending radius shall be 10 times
the diameter of the cable. Use a tension-monitoring device to ensure that the maximum
pulling tension that may be applied to the cable to be pulled into a conduit section is not
exceeded. Provide replacement cable if cable manufacturer’s maximum pulling tension is
exceeded at any time during a pull.
B. Cable shall be carefully inspected for sheath defects or other irregularities as it is paid out
from the reel. When defects are detected, pulling shall stop immediately and the cable
section shall be repaired or replaced at the discretion of the Owner. A system of
communications shall be maintained between pulling and feed locations so that pulling
can be stopped instantly, when required.
C. Adequate care shall be exercised when handling and storing reels of cable to prevent
damage to the cable. Cable with dents, flat spots, or other sheath distortions shall not be
installed.
D. All cabling shall be run continuous with no splices between termination points.
E. All cable shall be routed in such a way as to minimize EMI and RFI interference. Cables
shall be routed to maintain the following minimum distances from noise producing
devices:
5 inches from power lines of 2 kVA or less.
12 inches from fluorescent and HID ballasts
36 inches from 5 kVA or greater power lines
40 inches from transformers and motors
3.4 GROUNDING
A. Ground equipment, conductor, and cable shields to eliminate shock hazard and to
minimize to the greatest extent possible, ground loops, common mode returns, noise
pickup, cross talk, and other impairments.
