Hi,
I have had a stable Simplisafe installation or some years now. Of recent I am getting the 'panic button not responding' errors. The battery is OK, the battery connection is OK, I have tried keeping the panic button right next to the keypad, or close to the base station, but i still get the error. The last time around, I plugged in the USB fob into the base station to check if the panic button was registered, it was and after i re synced the base station, and ran a test mode sequence, the panic button error went away.
Now it has come back. Do i have a defective panic button?
