Systems with a single master station:Ensure that you have a jumper in place between “E” and “-” on both the master station and the door station.
Systems with multiple master stations:With multiple master stations, the jumper between “E” and “-” is removed on both the sub/ door stations and master stations. With the removal of this jumper, a 3rd conductor is needed, connecting the “1”, “E”, and the “-“ terminals from the door/sub station to the master station.
Manually shorting the “E” and “-” terminals will also generate a tone. This can be done to verify the hardware is not damaged. Note that the screws are not conductive, only the metal plate surrounding the screw.
If there is also a missing call tone, check both the numbered (ex. 1,2,3) terminal and “E” terminals to ensure connections are made. The numbered terminal and “E” carry the communication once the talk button is pressed.
When the Key button is pressed while in communication, 9.5v DC should be metered on these terminals (note that the screws are not conductive). From the RY-PA, a continuity closure should be seen on the yellow wires at this time.
