Relay Switch for External Devices

The relay switch for external devices allows the radar speed sign to trigger external devices* such as cameras, flashing beacons, and audible alarms to deliver additional warnings or messaging; or allows the external device to trigger the radar speed sign.

The relay switch option is available for use with the TC-600 and TC-1000 models. It can be programmed to trigger external devices based on:

  • Time and/or Speed
    Triggers messages or alerts based on time of day and excessive speeds. Especially useful for school zones or event areas.
  • Temperature
    Triggers messages or alerts based on temperatures. Especially useful to notify drivers of hazardous road conditions or other weather related warnings.
