    The Value of DHC's Intellisense™ Technology

    Leviton's line of Decora Home Controls™ (DHC) products feature exclusive Intellisense™ technology and deliver the reliability you depend on in powerline carrier home controls products - even in applications where electrical "noise" is present on the AC power line. Leviton's Intellisense™ technology assures excellent noise immunity without reducing command signal sensitivity so that top performance of the DHC system is assured.

    Powerline Carrier Signal
    Figure 1 shows a typical powerline carrier signal. Note that there are "empty" signal windows in the coded sequence.
    Noise
    Figure 2 shows what can happen when there's noise on the powerline while a command signal is being transmitted. The noise fills in all the signal windows, disrupting the coded sequence. As a result, the receiver cannot hear the command signal and does not respond.


    DHC reliability will boost your home controls business
    Leviton's DHC products featuring Intellisense™ technology deliver the most reliable performance of any powerline carrier home controls products available today. With fewer call-backs due to noise related problems, DHC installations become much more profitable. A new level of customer satisfaction also means more DHC business for you.

    Noise on the line- A part of every electrical system
    Powerline carrier home controls systems are easy to install because the home's existing AC wiring is used to carry command signals. However, in many homes, electrical interference can prevent receiver modules from operating properly. Electronic equipment found in virtually every household generates disruptive noise interference: TV's, VCR's, stereo equipment, computers and peripherals, air conditioners, FAX machines, electronic lighting ballast and many other electronic devices.

    How noise can disrupt powerline carrier systems
    Powerline carrier systems transmit and receive command signals at the zero crossing of the AC power curve. That's because electrical noise is at a lower level here than at any other point in the cycle. The zero crossing point is the Signal Window where receiver modules listen for the special coded command sequence. If the receiver hears a steady stream of signals in every signal window, it interprets this as random noise and does not respond.

    Amplifying the command signal may not solve noise problems
    Problems from noise interference are more related to receiver sensitivity than to signal strength. The sensitivity of a receiver determines the minimum amount of signal it can recognize. In order to deliver reliable performance in a variety of applications, powerline carrier receivers must be sensitive to command signals that are lower than 1/10 of a volt (.100) volts). Boosting the command signal does not change a receiver's sensitivity. No matter how powerful the command signal is, the receiver will still be sensitive to noise that's only a fraction of a volt, and noise will still be capable of disrupting the system's operation.

    Automatic Gain Control is needed, but not just any kind
    Automatic Gain Control (AGC) is a special circuit that adjusts receiver sensitivity to help eliminate noise interference. While Automatic Gain Control can be very effective in reducing noise problems, some types of AGC circuits yield mixed results when it comes to overall system performance. Until now, only a "non-gated" type of AGC was available in powerline carrier receivers. Non-gated AGC circuitry is not synchronized with the signal window. Instead, non-gated AGC desensitizes a receiver to high noise levels that occur throughout the entire AC cycle. Powerline carrier receivers are only affected by noise within the signal window, which is the lowest level of noise in the entire AC cycle.

    Therefore, non-gated AGC desensitizes the receiver from noise to such a degree that it also desensitizes it to command signals. There are installations where non-gated AGC circuitry can create as many problems as noise does.

    A New Built-in Feature Provides Outstanding System Reliability

    Leviton's DHC receivers feature Intellisense™ technology, the right type of Automatic Gain Control Leviton DHC receivers use Intellisense™ technology, a special gated-type of AGC, to help eliminate noise problems. The Intellisense™ gated AGC circuit is ideal for powerline carrier systems because it only operates during the signal window when receivers listen for command signals. Noise levels in the signal window are never as high as they are during other portions of the AC power curve. Therefore, Leviton's Intellisense™ gated AGC will desensitize a receiver to noise signals with only a minimal reduction in command signal sensitivity. The result: problems from noise interference are dramatically reduced without affecting overall system performance.

    Leviton's new Intellisense™ technology is built into DHC wall-mounted switch and receptacle receiver modules. These devices are installed exactly the same way as they were before, and there's no change in their popular Decora designer styling, either.
