My new house has a DSC/ADT alarm system that I’m locked out of after trying various codes suggested on here. The system has motion sensors around the house but I have pets and so wouldn’t want to use these anyway. I simply just want a system that I can alarm and if any doors or windows are opened, for the alarm to sound.
Would I be better trying to get this system working and adding some contact sensors to doors and windows or should I think about starting a-fresh?
If keeping the existing system who would be able to reset it and set this up for me? I tried calling the security company stickers I found around the house and was told a sales member from my area would be in touch. I heard nothing and don’t really want to chase them to spend my money. What kind of company should I be looking for?
