Setting up doors
Each door (or barrier) is controlled and monitored by a set of peripheral devices:
• IN Reader – a identification device (e.g. a card reader) that can identify a valid
credential (eg a card) to grant access to the protected area behind the door /
barrier.
• OUT Reader – an optional identification device (e.g. a card reader) that can
identify a valid credential (eg a card) to allow exit from the protected area.
• Door Contact (DrCnt) - a sensor that monitors the state of the door (open or
closed state)
• Request to Exit (REX) device – A switch or sensor that allows a person to unlock
the door without a valid identifier (eg a card) to exit from the protected area. A
REX device is not needed if and OUT Reader on that door is applied.
• Door lock / door strike / magnetic lock - a locking device that is controlled by the
panels Door output
Note: When wiring doors use separate cables for readers and monitoring / locking
peripherals
