Sleeping areas are typically surrounded by a curtain of Electric Fields from live electrical house wiring. The offending wiring is located inside the ceilings, walls and floors and is used to supply power to lights and receptacles in a particular room. These wires constantly emit Electric Fields even when all lights, electronics and appliances are turned off. These Electric Fields can only be eliminated by shutting off the power at the source (i.e. flipping off a breaker / removing a fuse). This is effective but not practical in most cases, so we came up with another solution. Our Automatic Demand Switch works by automatically shutting off the power at the breaker panel / fuse box, when there is no demand for it. The Automatic Demand Switch continually monitors the power requirements of the circuit and automatically restores power when necessary. This approach deals directly with the source of the problem and offers effective protection form AC Electric Fields including Dirty Electricity. This can be verified with a Body Voltage Kit or an AC Electric Field Meter.

THEORY OF OPERATION 

AC Electric Fields are produced by the presence of electricity. Their strength is determined by voltage; the higher the voltage, the stronger the field. AC Electric Fields are radiated form live electrical wires and generally travel 6-8 feet from the source, but in some cases further. An electric field will exist even when a device is not in use (turned off). In other words, these sources produce a continual emission. AC Electric Fields have a natural attraction to ground and are considered low frequency electromagnetic radiation. (5 Hz –400,000 Hz).

The Demand Switch was designed to eliminate the radiation of AC electric fields on a single branch circuit at the source of the problem, the main electrical panel (MEP). Controlled circuits typically include the sleeping area and adjacent living spaces. The Demand Switch works by automatically shutting off the power at the MEP, when there is no demand for it. Each demand switch controls a single branch circuit or single circuit breaker and switches the hot/black wire on and off. The Automatic Demand Switch continually monitors the power requirements of an individual branch circuit and automatically restores power when necessary. This automatic switching is load or current dependent. The demand switch is rated for 16 Amps AC and is compatible with standard and arc fault circuit breakers.

 

Note:  The Demand Switch simply interrupts the hot wire and switches it off and on. The switching is load dependent.

 

  • The demand switch has 2 modes of operation Protection mode and Normal mode. Protection mode means the 120 VAC will be switched off, thus protecting you from AC Electric Field exposure. Normal mode operation means the 120 VAC will be left on as in normal line conditions.
  • The front of the demand switch has 3 important items, the control lights Net and Load, the On/Off Switch and the load Current Adjustment Potentiometer.
  • The Net LED will illuminate green when power is applied to the device. The Load LED will illuminate green when the demand switch is in “protection mode”. In this mode the switch supplies a 9 VDC monitoring voltage to the circuit. The Load LED will illuminate red when the demand switch is in “normal mode” and supply 120 VAC to the circuit. Think of it as green is good, and red is a warning.
  • The yellow On/Off Switch located on the front of the demand switch will physically toggle up and down as the demand switch changes modes. You will hear a gentle clicking noise as it automatically changes position. Up is “normal mode” where the load LED is red and down is “protection mode” where the load LED is green.
  • The Current Adjustment Potentiometer is used to set the desired level of trigger current to control mode changes. The level is adjustable form 0 mA to 100 mA and can be adjusted with a fine slot screwdriver. When the circuit draws more current than the level of current set on the current adjustment potentiometer, the demand switch will be in “normal mode” supplying 120 VAC to the circuit. When the circuit draws less current than the level set on the current adjustment potentiometer, the demand switch will be in “protection mode” switching off the 120 VAC. A black dot beside the dial marks the Default Position and is recommended as the standard setting. The automatic feature of the demand switch can be bypassed when the potentiometer is turned completely counter clockwise, to the 0 mA position. When in this position the demand switch can be controlled manually by moving the toggle switch up or down. Please be gentle when rotating the dial.

 

LIMITATIONS 

The demand switch is designed for bedroom circuits with 120 volt lighting systems such as incandescent and halogen. Transformer based lighting systems will impede the automatic “Turn ON” function of the demand switch because of their non-linear load characteristics. To achieve a low EMF environment, the use of transformer based lighting systems is not recommended. However if change or removal is not possible then a constant load resistor can be installed across one of the lights or switches which will allow proper function. This would also apply to dimmer switches and compact fluorescent bulbs, “CFL’s”. This resistor should be installed on the load side of the light switch thus creating a constant resistive, linear load that the demand switch will recognize. See installation schematics for details on installation.

Another consideration is devices that create a phantom load. A phantom load occurs when a device always draws current even when it is turned off. Some examples are Alarm Clocks, TV’s, DVD Players, Stereo Equipment, portable music players and power adapters / charging units.

Items/appliances which can disrupt automatic function when installed on the controlled circuit: Smoke Detectors , Door Bell transformers, TV, VCR, Alarm Clock, Dirty Electricity Filters, Some GFI Outlets, Electronic Ceiling Fans, Fluorescent lighting (transformer based), Low voltage lighting (transformer based), Low voltage LED lighting, Compact fluorescent bulbs “CFL’s” (transformer based), Dimmer Switches, Electronic washing machines, Electronic Dish Washers, Refrigerators, Furnaces.
