About error scenarios on the ADAM box (explained)

When a failure on recording servers, hard drives or cameras is detected, the ADAM box' pins indicates which type of failure you are experiencing. If pin 0 is on, it indicates that a failure has been detected (or that the Test button has been pushed), if pin 2 is on, it indicates there is a recording server failure, if pin 3 is on, it indicates a hard drive failure and if pin 4 is on, it indicates that there is a camera failure.

The Test button has been pressed to show pin 0/error code 0x01.

Name	Description
Recording server failure:	The error code is 0x05, and pins 0 and 2 on the ADAM box are raised (pin 0 on means 0x01, pin 2 on means 0x04, so total 0x05).
Hard drive failure:	The error code is 0x09, and pins 0 and 3 on the ADAM box are raised (pin 0 on means 0x01, pin 3 on means 0x08, so total 0x09).
Camera failure:	The error code is 0x11, and pins 0 and 4 on the ADAM box are raised (pin 0 on means 0x01, pin 4 on means 0x10, so total 0x11).
A hard drive failure and a camera failure at the same time:	Pins 0, 3 and 4 on the ADAM box are raised (pin 0 for both hard drive failure and camera failure, pin 3 for hard drive failure, and pin 4 for camera failure).

When you click the Test button in System Watch, it raises pin 0 (and only pin 0) for a short while on the ADAM box (as seen in the screenshot above).
