I have a comfort system installed at my house and couple of months ago I upgraded UCM ETH03. Since then everything has been going fine.
There was a thunderstorm in our area few days ago and a loud cloud burst was heard over our house with possible lightening strike to our roof. Soon after this, our alarms went off, the outside siren was activated. The keypad inside house displayed RS232 communication failure with Slave 1. Since I was not home at the time, I asked my wife to disconnect Comfort (by turn AC input off and disconnect battery) which helped to turn siren off.
When I arrived in evening I connected Comfort back to power, tried to turn off siren from keypad. I checked RS232 cable from main board to SEM (slave), reinstalled my backup files into comfort. This resolved error displayed on keypad but siren still kept going.
I eventually disconnected siren from Comfort as its was becoming annoying to neighbours.
Everything else is working fine since, except if I connect siren cables back to comfort, it activates siren and sound doesn't turn off.
I would appreciate your help in resolving this error.
Thanks
