Radio Remote controls

Each button on each sender sends a unique coded signal (one of 4 billion codes).

A simple set-up procedure enables any chosen receiver to respond to the signal from any chosen sender button. The sender button then controls the receiver (and its connected load). This simple procedure is repeated, creating links between various sender buttons and various receivers.

As shown, almost any control set-up is possible; from a single room to an entire building.

For the simplest set-up, one receiver can be controlled by one sender.



Any receiver can be programmed to respond to the unique coded signal from any sender button. Hence, a sender button can control any number of receivers simultaneously.

Also a single receiver can be controlled by up to 15 sender buttons.

These control combinations can be mixed and matched, making it possible to have almost any control set-up desired; from the simplest single room to an entire building.

In the above control set-up, one button on the left hand sender controls the first receiver. A different button on the left hand sender controls the first and second receivers simultaneously, and so on.


Typical penetration of radio signals


The radio signals cannot pass through the entire length of walls.

The radio signals achieve a range of approximately 30-50m inside a building; 100-150m in free air.

Brick walls: approx. 60-90% penetration Timber framework with sandwich plasterboards: approx. 80-95% penetration Reinforced concrete: approx. 20-60% penetration Metal walls: approx. 0-10% penetration Conventional glass: approx.
70-90% Insulating glass (with vaporised metal coat): approx. 30-60% penetration
Plastics: approx. 80-95% penetration
