Note:
The Alarm input hardware interface is normally open by default. So only the normally open
signal is allowed. It can be linked to the buzzer of the card reader and access controller,
and the alarm relay output and open door relay output.
For single-door access controller, the Wiegand card reader 1 and 2 respectively correspond
to the entering and exiting card readers of door 1. For two-door access controller, the
Wiegand card reader 1 and 2 respectively correspond to the entering and exiting card
