Direction on Directional Sound

Directional sound technology is a quantum leap for fire-emergency egress systems. Along with standard audible-visible devices, directional sounders allow designers to specify "audible exit signs" or map egress routes to the nearest exit. Using broadband, multi-frequency sound, directional sound is adaptable for two different applications. In a Type 1 installation, the intent is to place a sounder near each exit, stairwell or area of refuge as an audible cue for locating an egress during an emergency. Type 2 uses directional sounders to guide occupants along an escape route.
