Telephone Remote Control

This kit offers new and exciting possibilities for telephone lines, since it is possible to turn on or off up to three devices over the telephone. It is also possible to check the condition of a switch (open or closed), even at the other side of the world. Example: when you are away on holiday, you may switch on and off the lights from time to time, check the alarm or turn on the heating before you return home.
