If you're experiencing a 'DEVICE FAIL xxx xxx = ROX xxx = RIX xxx = Kpd xxx = Trd xxx = Pnl' error on your Pyronix Security System, it indicates that a wired device on the RS485 bus has been lost. To resolve this, identify the device, check that its address matches the programming, and inspect the connections and cabling. If everything appears correct, reboot the device, followed by a reboot of the End Station.
