I've got an old menvier ts700 intruder alarm installed about 25 years ago and haven't used it for over a decade. It's gone off a few times recently so would like to completely disable/disconnect it but there is nothing to show me how to do that in the useranual/online I'm not that practical on such things. ..is it a straightforward job?(I have my code plus what looks like factory reset code) Grateful for any assistance
