KAC develops ExitPoint, a directional sounder designed to reduce building evacuation times during fires by as much as 75% |
|
In the great majority of commercial and industrial premises, the building's fire system is the most likely method of warning about a potential threat to the occupants. The typical audible visual warning generated by the system alerts the occupants to the fact that there is an emergency, but doesn't provide any help or guidance to show people the optimum escape route. To address this important issue, KAC has introduced ExitPoint, a directional sound technology which, triggered by the fire system, instinctively attracts people towards its source in both good and poor visibility. The units generate sound pulses of low, medium and high broadband noise that make it possible for people to identify accurately the location of the source. Directional sound is recognised by a primitive part of the human brain and because of this people are instinctively drawn to the noise. They can therefore be aurally directed to the nearest emergency exit, reducing evacuation times by up to 75% in tests.
ExitPoint operates at 24VDC, has five user-selectable power settings so that it can be optimised to its installed environment. It is also available with an optional voice messaging capability that will reinforce the meaning of the tones to people, advising them that following the tones they are being led to the nearest emergency exit, further improving the effectiveness of the units in reducing evacuation times. Different tone combinations are also programmed into the unit that people instinctively recognise and follow. These combinations are designed to instruct occupants that they are nearing an exit, a stairway up or a stairway down.
