ELECTRO-TECHNOLOGY FOR INDUSTRYSeeing and hearing –double alarms warn better!Visual-audible signalingdevices offer double theamount of safety in onepackageVisual-audiblesignaling devicesThere are many industrial areas of use for signaling devices thatare associated with adverse environmental conditions and higherdemands, making the mutual assistance of acoustic and visualsignals necessary. For example, when signals need to be noticedat great distances.Two scenarios make this clear. Visual signals, for example, areeasily recognisable in the dark. However, as soon as there issunlight, other lights, the factory lighting or welding fl ashes, theobserver is faced with a barely distinguishable light smog. Therefore,acoustic assistance of the visual signal is necessary.The same applies to acoustic signals that have to penetrate throughmachine noise, environmental noise, voice noise, echoes, runningmotors and hearing protection. They are only reliable in being noticedwith visual assistance.155
