Outdoor NoiseSign Overview

The NoiseSign is a wall-mounted sign that lights up when the noise levels are too high. With protection against the weather and high dust levels, this version of the NoiseSign is ideal for outdoor use.

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.

Range and Applications

Due to its very wide range of operation, 40 to 114 dB(A), the NoiseSign is suitable for most applications. Around hospitals, schools, or other quiet environments, 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.

Display Settings

For use in differing environments the brightness of the NoiseSign can be adjusted. In a bright area it would be set to its brightest, but for use in a hospital it might be set to a less intrusive level.

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.

Hospital Noise

  • Level adjusts to a very quiet 40 dB(A)
  • Brightness can be reduced for sensitive areas
  • Attractive wall-mounted design

To remind staff and visitors outside the hospital, at the entrance or in smoking areas, to keep the noise levels down and not disturb patients.

An indoor version of the NoiseSign are also available for use in corridors and treatment rooms.

Schools and Libraries

Mounted near the entrance, playground and outdoor rest areas, the all-weather NoiseSign reminds people to reduce noise.

Entertainment - Pubs & Clubs

Many noise complaints aimed at entertainment venues come about because of noise from visitors leaving the club or whilst standing outside smoking.

Mounted outside the venue, the NoiseSign helps to reduce complaints from local residents. It reminds visitors that they are no in a "Quiet Zone" and so should keep their voices down.

Installing the NoiseSign

The NoiseSign is very quick and easy to install:

  • Select the sound level at which to light up
  • Fit to the wall with two screws
  • Plug in the mains power supply

The trigger level is adjustable between 40 and 114 dB(A) in 1 dB steps. The adjustment is made using controls that are usually out of site on the back of the unit.

Mounting on the Wall

The sign is fixed to the wall or other suitable surface using two screws.


For a single sign, the only connection to make is for power. A power adapted is included and this should be connected to the NoiseSign and then plugged in to your power outlet. The power adapted should be plugged in indoors, an extra 9ft weatherproof extension cable is included.

Noise Beacon

The NSB-RED and NSB-BLUE are low power, high visibility LED beacons that connect to the NoiseSign to give a clear warning of high noise levels. They light up at the same time the NoiseSign lights up.

  • Low power, high visibility red or blue beacon
  • Up to three beacons on one NoiseSign
  • Weatherproof to IP65
  • Includes 10 m (32 ft) of cable
  • No additional power needed

Ordering Information

The noise beacon does not work on its own, it must be connected to the NS-QZON NoiseSign. You can connect one, two or three beacons to each noise warning sign.

The order code for the noise beacon is NSB-RED or NSB-BLUE, and this includes a 32ft cable to connect back to the NoiseSign or to daisy-chain to another beacon. The beacons get their power from the NoiseSign, so no extra power supply or power outlet is needed.
