There doesn't seem to be any life to it when I connect the 12v There is nothing on the LED segment.
I have tried moving all the dip switches and still nothing. I would have expected some sign of life with the 12 v connected.
I have programmed it and loaded the numbers and the message. The last bit is the alarm to the dialler. I have the +12v and 0v, is it only one cable from the bell trigger to the dialler trigger?
