My insteon module is constantly beeping…

I’ve tried hooking up a SwitchLinc Dimmer model 2476D, and I’m getting a continuous tone.

According to Smarthome, In the SwitchLinc, KeypadLinc, and ToggleLinc dimmer models revision 5.0 or higher, there is a detection circuit that tests the load (your lights) for mis-wiring or an incompatible load when power is first applied.

The Insteon module will test the circuit, and if it fails (or your load or wiring wrong), the sounder will beep continuously and no control (local or remote) will work.  SmartLabs did lots of testing, to try to ensure that the units would not false trip…
