Each AC-425 panel controls an entrance. The behavior of the panel is
controlled by DIP switch settings.
Select the appropriate DIP switch setting to operate the panel as either a single
door, a double door, or four doors (see Section 5.3).
Access control panels, configured as either single door or double door
controllers, have two readers, IN or OUT. Access control panels configured
with the MD-D04 expansion as either double door or four-door controllers
have four readers.
