READER LEDS
The Openpath Smart Reader's LEDs indicate the following:
● If the center dot quickly switches between multiple colors and outer ring quickly spins once,
the reader has just received power
● If all lights are off, the reader is not connected to power (check to see if the power wires are
swapped)
● If the center dot is flashing red, the reader is connected to power but cannot communicate with
the ACU (check to see if the +B and -A lines are swapped)
● If the center dot is solid blue, the reader is connected to power and can communicate with the
ACU, but has not been configured as an entry in the online portal
● If the center dot is solid green, and the outer ring lights up and spins, that means the reader has
been identified via the Control Center.
● If the center dot is solid white, then the door is locked
● If the outer ring is solid white, then the door is unlocked
