ACON has a few minor changes.
The Red indicator on the front panel will always be on when the system has power (+12VDC supply operating). It will not go out when the EXIT button is pressed, as it had prior to today.
Added a Red light to the back of the box, next to the glass. This light is on when the door is locked. So, when you scan your valid card, the light should go out and the door may be opened. It will then go back on when the door locks again, after about 15 seconds.
