Hello,

My Telegraph Transmitters are in a 100mA loop that is supplied power through a Power Regulator. It appears that my connection to the ground point in the building is correct, but nothing codes out when it goes into ground mode, although I can hear the transmitter coding out correctly. What am I doing wrong?

 

Use two wire link with your transmitter, do not ground your wiring separately.

Thanks for your response Dave, could you elaborate a little bit, please?

A little bit of background I didn't bring up before:

This is part of a fire alarm reporting proprietary system. The grounds are being used as a backup method of connecting to the receiver

 

As with all sensitive signals, local grounding leads to the problems you have describe.
Contact the supplier of the alarm system, they can explain it in detail.
The redundancy you describe is not redundancy in a real sense, as that requires independent installations.
