I have an old burglar alarm system (GE) with wireless GE smoke detectors model 60-848-02-95, NX-491NT The sound is emitted from Professional Installer PI-IDSP 15w8ohm indoor speaker. Since I no longer use Alarm Technology but the burglar alarm system still works, I found the "listener" will not work even with the microphone facing the speaker and only 1 inch away. If I can get the listener to work, this would be most idea which would enhance my RING system considerably. Did I have a defective listener, or is it just not compatible??
