The Veritas 8 alarm ( internal sounder only) goes off intermittently, even though it is not set. The outdoor alarm sounder does NOT go off ( presumably because it is not set). This can occur at any time of the day( even 4.00am!) ; often with a gap of a week or more. A local security " expert" disconnected the tamper system, indicating this would clear the problem. It has not. Any ideas please. Thanks.

I would replace the battery inside the control unit,turn mains power off before opening the panel
and get the tamper circuit back online,(but get some one knows what there doing )
