SoundEar 2 Outdoor Industrial Noise Warning Sign - Weatherproof - [NM-SE2IND-W]

SoundEar 2 Outdoor Industrial Noise Warning Sign - Weatherproof - [NM-SE2IND-W]

The SoundEar 2 Outdoor consists of a standard SoundEar 2 Industrial Noise Warning Sign fitted inside a wall-mountable weatherproof case. A microphone is mounted on the base of the enclosure, fitted with a suitable windshield. A power cable also enters the bottom of the enclosure.

Outdoor Noise Warning Sign

The SoundEar 2 Outdoor Industrial is a noise activated sign for use outdoors, in any weather, and is also suitable for use in environments with high levels of dust. It provides an immediate warning of high noise levels.

Instant Noise Warning

This outdoor version of the SoundEar has all the same functions as the standard SoundEar 2, but comes with the additional weather protection and cabling. The green light is on all the time to remind people that the noise is being monitored. When the sound level gets close to the trigger level (within 5 dB) the yellow light comes on as a warning. As soon as the level goes above the trigger level the red light comes on - it is time to act to reduce the levels or deploy hearing protection.

Features

• Weatherproof outdoor noise activated sign
• Lights up when noise levels are too high
• Green = Monitoring : Yellow = Getting loud : Red = Too loud
• Adjustable trigger level from 40 to 115 dB(A)

Applications 

• Outdoor and dusty environments 
• Factories 
• Industrial sites 
• Hearing protection - time to act 
• Intermittent Noise - warns when it gets high 

The weatherproof noise sign can be mounted on a wall in an area of varying noise levels. It is particularly helpful in areas where the noise levels are only occasionally high, so people know when to take action to reduce the levels or protect their hearing. It will continuously measure the sound levels using its built-in microphone and light up to warn when the levels are too high and it is time to take action. 

Installation and Setup 

Installation of the SoundEar 2 Outdoor consists of two parts: mounting it on the wall and setting up the trigger level. 

• Wall Mounting -With the front cover of the enclosure removed there is access to four mounting holes through which the sign can be fixed to the wall. 
• Power- Power is provided to the outdoor noise warning sign by a 24 VDC adapter, which is included. The power adapter should be mounted indoors (it has no weather protection) and connects to the noise warning sign via a 10m extension cable, which runs through a gland directly into the base of the noise sign enclosure. 
• Setting Up - Trigger Levels - You need to choose the level at which you want the noise sign to light up. In some situations this can be done by trial and error. Set a level and see if that works, adjusting as necessary. A more scientific approach would be to use a sound level meter to measure the sound level at the position of interest and then adjust the noise sign to light up accordingly. To prevent tampering, the front cover has to be removed using a screwdriver to access the dial that sets the level. 

Noise Warning Displays 

The SoundEar 2 has three main display components in the shape of a standard hearing protection symbol: 

• Green light - Indicates that the sign is monitoring. Reminding people to keep the noise levels down. 
• Yellow warning light - Warns that the sound levels are getting close to the limit. 
• Red warning light - Indicates that the noise is too high. 

You choose the sound level at which the red light comes on. The yellow warning light comes on 5 dB below the red light.
