Fig 2. This summary of findings clearly shows there are problems with false alarms throughout Europe. Many countries employ verification techniques. Most still favour “call in” contact with the user to determine the cause. The largest proportion of false calls is down to user error and verification will not significantly improve this. Says the BSIA: “Clearly then, there are two areas that need to be addressed: product design and the user”.
