Echoflex Device Linking Limitations


How many Echoflex devices can I link to a single unit?


  • Control devices (switches/sensors) can link to unlimited number of output devices, as long as the output devices are within range.
  • Output devices (controllers) can link to up to 20 control devices.
    • NOTE: there are exceptions for some interfaces
      • Contact Output Interface: up to 19 switches/sensors total across all 4 channels (not 19 per channel)
      • Echo Echoflex Interface: up to 35 switches/sensors total across all 4 inputs (not 35 per input)
