FAQs
Why is my StarLink communicator sending nonstop 373 troubles from the communicator inputs?
Verify the control panel is not sending signals to the inputs (if used). Also verify that 12 - 25VDC regulated (filtered) voltage is being delivered to the communicator terminals TB1 and TB2. To verify whether the voltage is regulated, perform the following tests:
Remove power from the StarLink communicator, and re-power from a 12V battery. After the communicator is fully powered and has checked in, determine if the troubles/signals from the inputs are still being received. If you are not receiving the same troubles/signals, verify that the NAPCO NOC (www.NapcoNoc.com) has not put that signal "on test".
If the runaway signals do not return, it is likely that the control panel is powering the communicator with unregulated (unfiltered) voltage. We suggest using a StarLink communicator model ending with "CFB-PS" or "CB-TF", as these models are powered with a separate power supply and transformer, isolating the communicator from the control panel voltage.
