Fire alarm systems are the silent guardians of our safety. Ideally, you never need them. But when you do, safe operation is literally life-saving. The most advanced technological system is only as good as the user interface that bridges the gap between human and machine. The demands on these interfaces are far greater than with many other devices and systems, because here it is literally a matter of split-second decisions – as well as the prevention of false alarms. An inadequate interface is not just frustrating – in a critical moment, it can actually increase the danger.
