EAO – Your Expert Partner for Human Machine Interfaces Series 56 | Multi-Tone Sound Module, Self-Adjusting EAO, the expert for innovative, reliable and intuitive human machine interfaces (HMIs) expands the successful Series 56 range with a new Multi-Tone Sound Module (MTSM) which automatically adjusts its volume to the ambient noise. Furthermore, it can be custom-programmed to emit unique warning sounds and alerts for different situations. By intelligently sensing the ambient noise and self-adjusting the sounder’s level, the appropriate volume is set. This prevents excessive noise and simplifies the set up process. Material The sound module is designed to meet EAO’s very high standards of quality, reliability, durability and design. ■■ Speaker housing: conical and flush-mounting housing moulded from rugged polycarbonate (PC) according to UL 94 V0 ■■ Front bezel: Die cast Zinc (matt chromium plated) or Polybutylenterephtalate (PBT) according to UL 94 V0 in different colours ■■ Connection cable: Flame-retardant halogen-free polyolefine mixture Electrical characteristics ■■ Operating voltage: 16 – 63 VDC and 50 – 143 VDC ■■ Current consumption: < 50 mA in reference to voltage and volume Mounting The sound module shares the same design and dimensions of other Series 56 products. ■■ Fast front mounting into panel with three fixing screws (supplied) ■■ Glass mounting, or panel mounting Mechanical characteristics ■■ Connection method: cable, 4 wires with crimped metal sleeves ■■ Connector on request ■■ Wire cross section: 0.5 mm2 or 0.25 mm2 ■■ Cable length: 200 mm, other lengths on request Hexagon socket screw: M4 x 8 mm (x 3) SW 2.5 The following two degrees of protection are available: – IP69K (front) / IP65 (rear) – IP40 (front) / IP65 (rear) Typical applications ■■ Transportation ■■ Public-use equipment ■■ Pedestrian crossings Acoustic characteristics The «MTSM self-adjusting» offers six individual tone sequences that can be emitted at different frequencies, number of repeats and durations. A set of TSI PRM compliant tones commonly used in public transport applications are typically pre-programmed. Additional customised tone sequences can be easily and quickly created with the tone editor program. The volume can be pre-set so it is always a specified number of decib
