Warranty for kits
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). 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.
- a relay is included for one output: 10A / 250VAC
- automatic pick-up can be selected for ± 8 or ± 3 rings
- automatic hang-up if no code is entered within 20 seconds
- supply voltage: 12VAC / 300mA
- dimensions: 105 x 130mm / 4.1 x 5.1"
