I noticed via the comfort app last night that my system was reporting an RS485 comms failure with an IRIO.On investigating today, I've had a small fire :shock:
This panel is in a metal sealed/vented enclosure that controlls some of the garden lights.The board takes its logic power over cat5 from the main panel.The mains is supplied by an MK RCBO 6Amp (didnt trip)I can switch all the lights independently using mains switches and they all work fine.These lights havent been switched on recently.
It looks like something on the Relay Sub board has let go, and created a small fire.I'm not sure if the IRIO carrier board is damaged electrically. Its socket upstand is a bit melted. Both sub boards had their power leds on. 
So, the questions are:-should I expect this sort of failure ?-if I replace the boards what is to say it won't happen again ?-Would just the failure of a single sub-board cause it to report a comms failure, or is the main board damaged too ?-Chiu do you want more info to investigate ?-is there any good will discount / replacement on this ?
I will attached some pictures in a moment (already written all this once to then fail on attachment and lose it all :( )
Cheers,     John.
