The Multi-Tone Sound Module (MTSM) answers the need for a sophisticated device that will emit a range of different sounds according to the change in status of equipment or machinery. For instance, it can be used on trains to help the visually-impaired locate a doorway and notify them that a door is closing. It is pre-programmed with 5 standard tone sequences that are commonly used as warning, orientation, acknowledgment or approval signals, but it is a significant improvement over conventional buzzers because the signals can be modified according to the customer’s needs.
The MTSM belongs to the market-leading Series 56 range of switches – one of EAO’s most well-known products. The distinctive, brightly coloured switch has been successfully used in over 100,000 applications throughout the world. Among the other products in the Series 56 range are single and double-sided pushbuttons and indicators and secret-until-lit indicators.
