I currently have a bulldog garage door lock fitted to up and over door but after a speight of break-ins I'm looking to fit an alarm .I have power in garage so I'm looking to fit wired contacts to door and siren inside garage.I would rather have alarm go off as they are breaking in rather than pirs.Do I need to fit contacts to each corner of door? as I know they sometimes lever the doors up from the bottom or force the door in from the top.Is the a kit that does this or do I have to buy separates? I am diy capable any information advice gratefully received.
Thanks.
Thanks.
