Adds four more doors to the master controller.
A four-door slave control module that joins the master access controller over the CAN bus. It verifies cards, passwords and fingerprints at the door, and adds doors as the system grows, without breaking central management.
Capacity9 inputs and 5 relay outputs carry the lock, sensor and exit button lines of four doors.
Access controlIt applies anti-passback, multi-door interlock and multi-person unlock rules, and separates users as general, VIP, guest, patrol and block list.
AlarmDoor time out, intrusion, duress and tamper events are reported separately.
Reader connectionReaders connect over Wiegand or RS485, and the module joins the master controller through the CAN H and CAN L lines.
InstallationSurface mounting seats the module on the wall, and the watch dog function keeps the device from halting.
