Fibra devices work on 24V⎓ voltage.
The minimum allowable voltage for Fibra devices to operate is 8 V⎓. Such a voltage may be at the end of a line to which many devices are connected.
If the voltage on a device is below 8V⎓, a fault counter will appear on that device, and the Voltage field in the device States will turn to red color.
Thus, we recommend that you perform a Lines Power Test after installing the devices to ensure that they work correctly.
