9 All outlet locations will be noted on the attached floor plan drawings, and designated by outlet type. In classrooms, outlet placement must accommodate teacher and student needs for instructional delivery and student use. Outlets in the computer lab areas, and in the media center have different requirements than normal wallmount outlets. Details and suggestions for placement are provided herein. Classrooms - The typical classroom will contain two video outlets, one wall mount voice outlet and usually between two and five data outlets. One data outlet will be for use by the instructor, and two to four data outlets will be for use by the students. Blackboard Area Wall Mount Video Outlet & Instructor Data Outlet Wall Phone Outlet As shown in the typical classroom diagram, the front wall of the classroom is usually filled with blackboard. The instructor desk is generally placed in the front of the room near the corner of the blackboard area. The wall opposite the entrance to the classroom is generally an external wall composed of windows and HVAC equipment, and is unsuitable for routing cable and placing outlets. Window Wall Typical Classroom Wall Mount Video Outlet Student PC Area Video support needs to be provided at two ends of the classroom to provide the instructor some flexibility in where video information is displayed. Video outlets should be mounted at a height to correspond with and support the connection of a wall mounted TV. In some cases the wall mount video location and the instructor s desk are co-located in a front or rear corner of the room. Video and instructor data outlets can be combined in a single raceway to facilitate both outlets within a limited space. If the classroom s do not have wall mounted TVs, but utilize AV equipment on roller carts, the video outlet locations and mounting height should be revised to support the common location where moveable AV equipment is used in the classroom. Student PC Area Video Outlet Voice/Data Outlet A minimum of one data outlet should be provided for the instructor, however, two instructor outlets on opposite sides of the classroom may be desired to allow the instructor the rearrange the room and place his/her desk in the front or rear of the room. 9

10 Generally PCs in the classroom designated for student use are clustered against an exterior wall or side of the classroom. If surface mount raceway is required to support classroom outlets, when more than one data outlet is required for student PCs, multiple outlets can be fed Raceway from False Ceiling through a single vertical raceway. The raceway and surface mount boxes must be sized to accommodate the total quantities of cables routed through the raceway within NEC and ANSI/EIA/TIA maximum fill ratios, and allow proper bend radius and dress/termination of the cables. Computer Labs - Computer Labs have a high density of PCs in a small area, requiring a high density of connectivity. As opposed to installing 12 to 20 outlets within a single room to support the typical computer lab, it is recommended that a single outlet per wall be installed, and stackable hubs be utilized to provide connectivity to the student PCs in the lab. The instructor will still require video and data outlets placed strategically in the room as described for the typical classroom above. Depending on how the lab room is arranged, and what facilities are provided for routing patch cords, computer lab connectivity to all student PCs can be supported by a single data outlet and wall mount rack or shelves equipped with the appropriate stackable hubs. A distribution method for connection of the PCs to the hub ports via patch cords should be designed which keeps walkways and student work areas free of connecting cables and electrical extension cords. Adjacent to the data outlet that will support the lab hub(s), a wall mount swing gate, or fixed rack or wall-mount shelves should be installed to house the hub equipment. Surface mount raceway can be used to route patch cords between the hub ports and student lab PCs. Media Center - The media center generally has kiosk type areas throughout the room, which are set up for specific educational uses. Areas such as language arts, Internet access and interactive tutorial type instruction are typically found. Concentrations of outlets for a specific application can be routed and installed as shown above for student PC areas in the classroom TELECOMMUNICATIONS OUTLET INSTALLATION All outlets shall be installed in the following manner: Cables shall be coiled in the in-wall or surface-mount boxes if adequate space is present to house the cable coil without exceeding the manufacturer s bend radius. In hollow wall installations where box-eliminators are used, excess wire can be stored in the wall. No more than 12 of slack shall be stored in an in-wall box, modular furniture raceway, or insulated walls. Excess slack may be neatly coiled and stored in the ceiling above each drop location when there is not enough space present in the outlet box to store slack cable. In addition, each cable type shall be terminated as indicated below: 10

11 Cables shall be dressed and terminated in accordance with the recommendations made in the TIA/EIA-568-B document, the manufacturer s recommendations and best industry practices. Pair untwist of UTP cable at the termination shall not exceed one-half an inch. Bend radius of the cable in the termination area shall not be less than 4 times the outside diameter of the cable.
