My house got hit by lightening last night... Happiness and burnt wires. For some reason it was only the circuit with the house lights... and the house alarm. (I have a house alarm?)
It became apparent that there was a house alarm when it started going off at 4am in the morning. This poses 3 questions... Where is it, Why is it going off, and How do I turn it off. After a short amount of time it became apparent that the pin-code was not known so it was not possible to electronically disable the sirens/speakers. These were physically disabled. Next up... the buzzers in each circuit board hidden in cupboards and other wonderful places. Removing those circuit boards solved that problem.
Great stuff. 6 hours sleep and a headache. Now to hope that the next door neighbour doesnt try to evict us.
