System Sensor's new ExitPoint sounder uses Directional Sound to identify escape routes leading to perimeter exits. ExitPoint, fitted in conjunction with normal building evacuation sounders, offers a way to draw people to exits in perfect visibility and in smoke. Directional Sound technology consists of a broadband, multi-frequency low-, mid- and high-range signals. The distinct directional sound helps occupants find the exit and can even guide people up or down stairs.
