Hi guys, welcome everyone! Maybe you'll have any idea? Risco Lightsys 2, no issues over last 5 years. I assume the battery just died (due to its age) and this is what happened then: 1. Power outage in my house 2. Alarm can't boot - it turns on for 0.5sec and resets again and again 3. I disconnected all the sensors - it boots 4. Connected the sensors again - still up and running 5. I replaced the battery, just in case 6. Another power outage 7. Alarm is not booting anymore: If I disconnect the sensors - it's booting for up to 0.5 sec and resets If I disconnect the sensors and battery - it's booting slightly longer (maybe 2 sec) and resets again I managed to boot it once and it showed an "AC failure". It seems that the motherboard is broken - do you have any idea what else could I check before I'll start looking for a new one? Thanks!
