after a power cut my optima xm6 house alarm has locked up,none of the buttons work,i can't reset it!!?

Question

I have removed the cover and detached the battery then turn the power off but the siren keeps going (where is it getting power from?)When i reconnected the battery and power the box buttons still don't work

Answer 1

It's powered by the battery in the bell box. put the cover back on to close the tamper switch, the sounder should stop in 20 mins. Then you can reset it. You need to put the mains power back on though. Sounds like your main battery is flat if it went to alarm because of a power cut. (No hold off voltage) Replace the battery and it should be ok.

Answer 2

Call the people who maintain it. That is why u pay them.
