First, ensure that the OFF button is pressed at the master station. There is no visual indication if it is pressed or not. “Off” is the standby position when not using the intercom.
Then, Ensure that you have a jumper in place between “E” and “-” on the door/sub station. The wire from that position on the door/sub station is to be connected to the “E” terminal on the master station.
Manually shorting the “1” and “E” terminals at the master will also generate a tone. This can be done to verify the hardware is not damaged. If you get a call tone here but not when you press the door/sub’s call button, then short the wires at the door/sub. If you get a call tone by shorting the wires, but not when pushing the call button, then it’s possible the door station has been power surged.
All wire runs should be at least 20 inches from any AC source, and always cross at a 90 degree angle.
