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.
●
The DIP of RS-485 card ID is set as 1 and 4 by default. 1 is for
entering, and 4 is for exing. If the user has congured visitor
card, you should connect two card readers on the exing side.
