Need help for my ADT DSC Classic PC1555
I have an ADT DSC Classic PC 1555 with an LCD 55012 keypad. The main box is an Ademco Vista 10E. It is currently not monitored and last time I changed over to daylight savings time I must have made an error because it has started to automatically arm itself at 3:00 am each day. I can disarm it as normal but, if I forget and open the door without disarming it I don't get the normal 1 minute delay before it sets off the system. As this includes a very loud outside horn it is very annoying. Anyone have any idea how to reprogram it so that it will operate normally?
I appreciate any assistance you can offer me.
Thanks.

You must have a DSC system...it may have been installed in a vista can.
Read your manual, you can find it here:
