They’ll also give you wiring diagrams to give to the contractor; most of them will do it for free. Select Products Depending on the relative importance of the several factors, select appropriate components and test the integrated design to see if it will satisfy the goals. Control Voltage Some controls can be hooked to line-voltage power, and others must be connected to low-voltage (DC) power. For a new building, both are possibilities, but for a partial renovation, it may be beneficial to use low-voltage controls.
This chapter originally appeared as an article in EC&M; reprinted here with permission. 57 58 Advanced Lighting Controls ON/OFF OPERATION It may seem simple, but on/off operation is an area where many designers create an unworkable lighting scheme. For example, consider a metal-halide lighting system. Restrike time, which refers to the time it takes a lamp to begin giving off light after being turned on, is crucial for this type of system. Once metal-halides are shut off, they take several minutes to begin giving off light again after being turned back on.
Line voltage controls tend to be less expensive, but less flexible, than low voltage controls. If the area does not require low voltage components such as light-level sensors, a line voltage control may be adequate. Many lighting designers believe that electronic dimming ballasts will be the “future standard” for fluorescent lighting. Locate Products on Plans As you locate the controls, ask yourself these questions: • Is the placement appropriate? Make sure the controls are easy to locate and to access.
