Planning Structured Cabling: Selection Practice

| 8.4.10 | Closet I

Potential wiring closet I is located in the far corner of the building, next to the main entry. Its dimensions are approximately 2.4 m wide x 4.6 m deep. Room I houses the heating and cooling equipment for the building. All heating and cooling ducts to other parts of the building lead from this room. High voltage electrical conduit passes through this room along the outside walls. All walls are of concrete block construction, and are covered with fire-retardant paint. The room does not have a dropped ceiling. The floor is covered with ceramic tile. Lighting is provided by an overhead incandescent lighting fixture. The switch that turns the light on and off is located just inside the door. When the door is opened, it swings outward. Because the room houses potentially dangerous equipment, the door locks, and can be unlocked from either inside or outside the room.
