EAO – Your Expert Partner for Human Machine Interfaces Series 57 | Emergency-call Button EAO, the pioneer of illuminated pushbuttons and the expert for innovative, reliable and intuitive human machine interfaces (HMIs) has expanded its Series 57 range to include an emergency-call button. The emergency-call button with its raised bell symbol (conforming to TSI PRM & ADA) serves to call for assistance in public transport toilet facilities, in public buildings or at emergency terminals. The emergency-call button combines functionality and design. Two feedback rings illuminate when the button is activated. The robust anodized aluminium front ring protects the button against damage and avoids accidental actuation. The front is protected to IP69K and makes the emergency-call button ideal for outdoor use or applications in harsh environments. It shares the same design and dimensions as other products of the Series 57 range. The extra-large operating area enables a simple and safe operation in all situations.
