Just moved into new home fitted with this type of burgular alarm. Cannot afford engineers visit as out of work at the mo, and they don't want to help otherwise. Alarm panel seems to function in setting and disarming the alarm, with normal tones from the house internal sounder during setting/disarming, and when tested by opening the door. The outside alarm box doesn't seem to work at all despite a neighbour saying that before we arrived that it had activated outside once and turned off after a while. We have the manual and a password code (but maybe not an engineers code). We cannot set the time on the panel or access any of the other test functions. The manual tells you to go to 'set system' mode and say 'no' to display 'omit zone' and thereon to the 'program menu'. Unfortunately, when we say 'no' it just goes back to 'system off' mode' and doesn't allow us into any of the program/time/system test menus. Any advice ?
