Hi Sue, you have an intermitten tamper fault, The Active 5 control panel is more for the diy person, your battery should be changed at least every 5 years, but i doubt this is the reason for the false alarms, I have an ACT battery tester which tells me the condition of a customers battery in seconds, you dont, so change it regardless. At a guess i would say its your bell box tamper, but remember im guessing from this end as i have only got your 3 lines to go on,
I would suggest you call me, as a lot of people do from this site, give me an idea as to where you are, and i might be able to help, otherwise its gonna be a visit from your local rip off alarm company charging you a fortune, so be careful if you choose not to call me.
