28 00 00 ELECTRONIC SAFETY AND SECURITY
June 16, 2009
Fasten approved wire management hardware (bridle rings, j-hooks, etc.) to the building structure
and/or cable tray at least every 10 feet where not in conduit. Do not lay or fasten cables to electrical
conduits, light fixtures, piping, mechanical equipment, or ceiling grids.
Run wire and cable continuous from device location to the final point of termination. No mid-run
cable splices will be allowed except where cables must transition from one type to another (e.g.
underground cable to plenum cable). Provide the following where cable transitions are required:
1. Provide labeled terminal strips inside lockable cabinets at cable transition locations and
document locations in the submittals.
2. Label terminal cabinets and document labels in record documentation.
3. Provide the same number of conductors and insulator colors for each cable type from the
security device to the DGP location.
4. Where shielded cable is required, the shield must also be spliced.
Visually inspect wire and cable for faulty insulation prior to installation.
Provide bushings, grommets, and strain relief material where necessary to prevent abrasion of wire
and excess tension on wire and cable.
Make solderless device connections mechanically and electrically secure in accordance with the
1. Prepare wire ends for attachment to components in accordance with manufacturer
2. Wire nuts shall not be an acceptable means of connecting wire and cable.
3. Make cable connection for device terminations with crimp type connectors. Connectors shall
provide a hermetic seal and test probe access such that the circuit may be checked without
breaking the connection.
Neatly install and terminate wire and cable within DGP's, power distribution cabinets and other
security enclosures. Pull cables tight, remove slack, and route in such a way as to allow direct,
unimpeded access to the equipment within the enclosure.
Bundle and tie wire and cable with Velcro hook & loop type or similar cable ties.
Provide heat-shrink to insulate wire connections. The use of electrical tape shall not be acceptable.
Cover exposed high voltage (120 VAC and above) power terminations within DGP's, power
distribution cabinets and other security enclosures.
120 VAC emergency power dedicated to security will be provided by the electrical contractor.
Connect to AC power and provide UL listed power supplies and transformers to distribute low voltage
power to the system components as required.
