A solid amber/yellow LED indicates that the device is booting (upon power cycling, the device LED will be yellow (20-30s) and then there is a short beep and the LED turns red; indicating the device is fully booted).
If this occurs after a credential is presented* it is normally attributed to one of the following:
- Backfeed: This is generally caused by connecting an electric strike to the RC04's Red and Black wires without installing a Back EMF Diode Assembly in-between.
Can also be caused by voltages from outside the RC04 entering the device. Example: Connecting a wet DC output from a REX device to the RC04's REX input.
- In Rush: If a maglock is connected to the RC04's Red and Back wires without the integration of an in-rush suppressor.
- Overdraw: If the combined current draw for the locking device and any accessory devices being powered by the RC04 exceed the RC04's 600mA MAX output.
This includes a short circuit created by an approval. For instance, if the device is configured for Fail Secure and there is a short circuit between the red and black wires (could be a strike itself is shorted) when the output goes high it will short the device out by exceeding the 600mA output via a dead short.
*After presenting a Pure Mobile credential to the reader, the LED will illuminate Amber/Yellow before turning either Green for approval or Red for decline.
