Extended functions:
The fire linkage door linkage door has an alarm if it is not closed for a long time, an illegal intrusion alarm, an illegal card swiping alarm,
and a coercion alarm function (if the fire and alarm linkage expansion board is not connected, it only has a software interface alarm prompt
and drives the computer speaker to give an alarm. If the expansion board is connected, it has a hardware alarm output function and can drive
devices such as lights or sirens). The forced door status is normally open or normally closed, and the remote door opening function is available
Interlocking function (dual door and four door controllers have controller multi door interlocking function) Anti submarine return and anti tailgating function
Multi card simultaneous verification with door opening function, timed constant door opening function
Emergency door closing function (emergency double closing) with the first card opening the door
External password keyboard function (card+password, super pass password) for operators to manage permissions, departments, and areas, etc
