I've inherrited an SL compact alarm when moving home. I have the alarms codes for the engineer and both the user, but not the engineer manual. I've tried the ADE G3 install manual which seems to be similiar, but some of the program options do not work. The alarm was working fine, until I changed the user code. When exiting the house the alarm system will not set correctly and the exit tone is continous and doesn't go off. If I use the quick set option it works fine and the alarm sets and on entry the tone begins again. The quick set only give you 5 seconds to get out. I want to re-program zone 1 and reset the exit time, but I cannot with the similar install manuals I have. Does anyone have the correct install manual for the SL Compact?
