Product Name: dB alert - Personal Noise Activated Warning Unit Model NO.: DB-602 Trademark: HANDSUN Specification: CE Product Description dB alert - Personal Noise Activated Warning Unit According to industrial safety law, areas subject to hazardous noise must be clearly defined, and workers notified of the danger. In most industrial settings, the noise hazard will vary throughout the premises and employees are often mobile. This is precisely where the dB alert - Personal Noise Activated Warning Unit comes into play. dB alert activates only when the noise exceeds a pre-set level, warning exposed workers that noise levels have become dangerous and to put on their ear-defenders. Perhaps more importantly for the employee, this means that they will also know when they can legally take them off! Being of rugged construction, dB alert is suitable for most industrial situations. It comes complete with a pocket clip and the membrane keypad means that integrity and simplicity of use are maintained. dB alert also includes a vibrating alert, which gives the wearer the added warning of a mobile phone style vibrating alert to bring attention to the fact that dangerous noise levels have been exceeded. dB alert is a self-contained unit housing its electronics in a tough case, and is easily set-up to company specific levels meaning it will be ready for action within moments of leaving the box. The Ultra-bright warning LED is brilliantly lit when activated and is designed to catch the wearer's attention by using their peripheral vision giving an easily noticed warning.
