OASIS CSI (Certified Security Integrators) “Direct Attach” Warranty for ESS Devices Berk-Tek recommends installing a well-designed structured cabling channel per the TIA standards. This includes up to 100 meters of twisted pair horizontal cabling terminated on both ends with a modular jack and corresponding Category cables. In the TR, the cable is connected to the patch panel and on the device end, the camera is attached to the solids horizontal cable through an RJ-45 terminated patch cord to the workstation outlet. In some real world IP applications that extend outside the voice and data scope, such as security cameras and access point devices, there are circumstances that do not allow a jack-to-outlet scenario on the device end. The TIA-862 standard for BAS applications recognizes these circumstances and allows the elimination of a workstation outlet and patch cord at the device end, when deemed unsafe and unfeasible. This includes, but not limited to, applications such as cameras, access controls, industrial sensors, lighting and wireless access points. Berk-Tek’s OASIS 15-year warranty through the CSI program will cover a plug-ended “direct attach” when using any RJ-45 plugs that meet the most recent TIA standards, installed to best practices through the OASIS CSI training and provide proper test results. (Plug installation instructions are available from Berk-Tek.. See testing procedures further in this document). However, the plugs on the chart have been tested by the Nexans DCCC and are recommended: *For part numbers, see full catalog or Web site: www.berktek.com

Guidelines for best installation practices This guide is intended to provide basic guidelines for the installation of BerkTek copper cabling products. The use of this guide is not a substitute for installation training through the OASIS CSI program. Installation practices outlined in ANSI/TIA -568-C and the BICSI TDMM Manual must be followed.
Maximum Cable Lengths Per the channel and permanent link requirements of ANSI/TIA -568-C 90 meters horizontal cabling 10 meters total patch cables
Cable Slack It is recommended to provide additional cable slack at both ends to accommodate future cabling system changes Telecommunications closet: 10 feet Telecommunications outlet: 12 inches for twisted pair cables
Maximum Cable Pull Force •
UTP Cables: 25 lbs-f
Handling of Cable Boxes Boxes must be stored and handled in an upright position to reduce the chance of twisting and kinking the cable especially if the box is partially used
Cable Bend Radius UTP: 4 times the cable diameter or 1 inch
Cable Management and Pulling Practices Eliminate cable stress Control tension in suspended cable runs by limiting spans between supports to 5 ft or less Avoid tightly cinched cable bundles Avoid kinking during installation Avoid changing the geometry of the cable

Follow manufacturers’ recommendations for loading of cable trays and j-hooks. The use of tie wraps should be avoided. Staples are prohibited When pulling cable apply pulling force evenly to all conductors in the cable. Avoiding kinking the cable when dressing the cable. Avoid exceeding the maximum bend radius for the cable.
Connector Termination Follow the manufacturer’s guidelines for termination of connectors and patch panels
Plug Installation Guidelines If the direct attach method needs to be used, there are some guidelines for attaching plugs. Following these procedures will help to assure that the plug contacts line up and work properly. But, since there are no standards to attaching plugs other than lining up the conductors to match TIA-568-A or B, each plug design varies between manufacturers. Use these as guidelines, but refer to the manufacturers’ specific instructions and use their recommended tools: If there is a strain relief (boot), slide it on the cable Trim off 1” to 1 ½ of the jacket and untwist the pairs Align the conductors to match the proper color layout for either TIA568A or 568B, depending on the other end of the termination in the TR If there is a load bar or management bar, trim the conductors at a slight angle. If no load bar, evenly cut straight across (to make it easier to load in) Line up the conductors on the load bar and trim the excess wire once pushed through. There should be no more than a total of ½” of untwisted wire from the tip of the housing to the cable jacket Make sure that all conductors touch the end of the housing and are visible when looking thru the end of the housing If there is a strain relief, slide up to the rear of the plug housing Using the manufacturers’ recommended crimp tool, crimp the plug into place. This is a critical step because if done incorrectly the wires can become loose and lose end to end contact.

Testing Procedures for a Plug-ended Channel/Link A major concern is that in a four-connector channel configuration, most testers cancel out the first connection. At the device end, this would be the plug, which could provide a false “pass” reading. The following are general guidelines using Fluke Network’s DTX Cable Analyzer or IDEAL’s LanTEK or LanTEK II.
FLUKE DTX CableAnalyzer Cabling standards such as ANSI/TIA-568-C.2 defined two definitions for link testing: channel and permanent link. In the case of a direct attach, as shown below, it does not fit either the channel or the permanent link models. This is known as a modified link. This scenario, a “Direct Attach,” is referred to as a modified permanent link for testing purposes because it resembles a permanent link more than a channel link. This is used when the end devices, such as security cameras or BAS devices, are not attached through an outlet. This is recognized by the current TIA-862 Building Automation Standards and is currently in draft for the ANSI/BICSI-005 ESS standards. Fluke Network is currently developing their software to recognize this test set up.

Below is a compromise between what the standards define and the how to achieve acceptable test results. In this test scenario, no user patch cords are involved.
Step 1: Set the DTX Cable Analyzer to TIA Cat 5e or 6 Perm. Link Step 2: When you get this prompt, the DTX CableAnalyzer is correctly warning that this is not appropriate. Press the F3 key to continue and it will test and it will run as an Autotest Step 3: The tester will provide you with a “Pass” or “Fail” in the Autotest mode. The effect of the remote channel adapter is removed in the measurement. The channel adapter will normally add a significant amount of NEXT (near end crosstalk) to the measurement unless it is cancelled out. The DTX Cable Analyzer uses Digital Signal Processing to cancel out the NEXT in the adapter in accordance with ANSI/TIA-568-C.2 and IEC 61935-1. Return loss in the mated connection is also minimized, as the adapters contain RL calibration coefficients representing a nominal RJ-45 plug. Due to the unique way the DTX CableAnalyzer works, it will check the mated NEXT in the Channel Adapter.

IDEAL LanTEK/LanTEK II Step one – Calibration. Calibrate the tester following the on-screen prompts using either the included patch cords (category 6A F/FTP) or with high quality, factory made category 6 or better cords. Calibration step A: Normally two patch cords are used for calibration. In this case you will be using just one patch cord. Connect that patch cord between the two handsets and press F1 to begin. This process characterizes the patch cords to remove their affects from permanent link measurements. Calibration step B: Normally you would swap patch cords and proceed with step 2. In this case leave the same cord in place and press F1.
Calibration step C: This picture depicts the normal calibration process with two patch cords being used for calibration and testing. Disconnect the patch cord from the remote handset, leaving it attached to the display handset. Press F1 to test the cord in the open configuration. The handset will detect the length of the patch cord and begin its measurements at the end of the patch cord. Calibration Step D: You will not see this image on the tester. With no patch cord connected to the remote handset, press the Autotest button on the remote handset. The handset will detect that no patch cord is connected and will begin its measurements during field testing at the test adapter.
Step 2 – Attaching the tester to the “channel.” Attach the tester on both ends of the horizontal run. In the TR, set up the tester patch cord into the patch panel jack. On the camera side, attach the remote handset directly to the plug at the end of the horizontal cable.

Step 3 – Test. Set the tester to “permanent link” (versus a channel test) because you will need to get a read of the plug termination. Select either Category 5e or 6 to match the grade of installed cabling. (Note: If you tested a channel then you actually might get an increase in cable/channel performance as it will cancel out the patch cords that occurred in the calibration.) Step 4 – Test results. The autotest will give you a “pass” or “fail.” If NEXT or PSNEXT fails at the device side (Remote Handset) replace the plug at the end of the “channel.”
