Hi mate. I am currently in the process of selling my flat, which has an ADE Optima Compact alarm. My fiancee bought the flat and has never used the alarm since she moved in, but we would like to know if there is any way to re-activate it. Do you think it may be possible to reset the alarm code so we can do so? Unfortunately, as the previous owners have moved on from their last known address we have no way of locating the current code that may be fixed into the system. Any help would be appreciated.
