Activate Sensors When You’re Ready To Use Them

Add the Sensor Activation & Test Utility (EPOCH-ACTI) to start the sensor battery when ready to use the transmitter.

  • The reusable activator is battery operated and can be used for any sensors that are ordered as deactivated.
  • Transmitters must be activated within 6 months of shipment to ensure the full 2-month or 6-month active battery-life.
  • Sensors will be shipped with the battery running unless requested as “deactivated” when ordered.
    • Request “deactivated sensors” in the comments section when ordering sensors or systems.
    • Deactivated sensors require that the user has an EPOCH-ACTI on-hand or includes one in the EPOCH order.
  • The activator utility can also output two independent channels of data (sinewaves) for testing purposes.
