This kit makes it possible to turn up to three devices on or off over the telephone. It is also possible to check the condition of a switch (open or closed), even from the other side of the world. Example: when you are away on holiday, you may switch the lights on and off from time to time, check the alarm or turn on the heating before returning home. A major advantage of this circuit lies in the fact that audio signals are used to tell whether a specific output has been turned on or off. Operation is protected by a user defined code, which is simply keyed in from the telephone keypad. Uses now discontinued UM92870 DTMF decoder IC.
