The NoiseSign is a wall-mounted sign that lights up when the noise levels are too high. It can be used to warn workers to fit hearing protection, or to remind visitors in hospitals and libraries to keep their noise down.
The level at which the sign lights up can be set using controls on the back of the unit to anywhere between 40 and 114 dB(A) in 1 dB steps. It can be set to switch off immediately when the level falls, or to remain lit for 30 seconds. A small plate can be fitted over the controls to avoid tampering.
The Noise Sign is easily mounted to the wall using two screws, making it suitable for use on brick, wooden or plaster surfaces. It is lightweight so there is very little strain on the mountings.
Due to its very wide range of operation, 40 to 114 dB(A), the NoiseSign is suitable for most applications. In factories and other industrial applications, the trigger level will be set to warn workers that the noise levels have exceeded 80 or 85 dB(A). In a hospital, school, or other quiet environment, it would usually be set somewhere in the region of 45 to 60 dB(A) as a reminder to people to keep the noise levels down.

For use in differing environments the brightness of the NoiseSign can be adjusted. In a factory it would be set to its brightest, but for use in a hospital it might be set to a less intrusive level.
To deal with short and intermittent noise levels the NoiseSign display can be set to remain lit for 30 seconds.
For environments where the sign might not be easily seen, up to three remote LED beacons can be attached. These beacons can be set to flash to make it clear that the noise levels are too high. More information about the Noise Beacon...
