TIA568 Wiring Standards

How to decide which wiring pattern to use:

1. Does the job specification call out a wiring pattern?
2. Does the customer/end user have a preference for T568A or T568B?
3. Have patch panels already been purchased for the job? If so, they will probably be either T568A or T568B. The jacks should be wired to the same pattern as the panels.
4. Are you adding on to an existing wiring plant? If so, your new wiring should match the existing wiring.

If none of the factors above apply, either T568A or T568B may be used. It is important to ensure that the workstation connectors and the patch panels are wired to the same pattern. T568B is commonly used in commercial installations, while T568A is prevalent in residential installations.

FAP42TC Strategy II 4" 16W @ 70.7/100V Coaxial Low Profile Ceiling System

Atlas FAP42TC Strategy II 4" 16W @ 70.7/100V Coaxial Low Profile Ceiling System (2 Pack)


With an overall depth of 4″ (102mm) the FAP42TC is the perfect choice when high fidelity audio and wide, even coverage is required but space above the plenum is limited. For wall mount applications (tanning salons or surround sound) the short 4″ depth will even work in most stud wall installations. A simplified input section features a 4-pole Phoenix style connector for easy daisy chaining between speakers. A simple cover including combination 1/2″ (13mm) / 3/4″ (19mm) knock-outs is provided for installation ease. The popular Atlas Sound "C-ring / V-Rail" mounting system is provided for quick installation into drop tile acoustic ceilings and existing construction drywall. For new construction drywall applications the optional FAP42-TR may be used. All other popular features of the FAP42T are included on the new FAP42TC including the front mounted tap selector switch (which included transformer bypass for 8 Ohm applications), attractive press-fit grills, high performance 4″ polypropylene cone driver with 3/4″ (19mm) PEI tweeter and precision crossover components for smooth, even coverage.

Features:

  • Low depth (4") speaker system for limited space applications
  • Easy installation in drop tile or sheetrock ceilings via C-ring/V-rail tile bridge and "dog leg" mounting system (Included)
  • Enhanced quality 70.7V/100V internal transformers minimize insertion loss and maintain low frequency response while providing increased output for higher SPL applications
  • Front mounted tap selector switch for easy system tuning adjustments includes transformer bypass setting for 8 ohm direct coupled operation
  • "Press fit" grilles blend better into contemporary architecture
  • UL Listing Pending
