Access Controllers
Access controller
Bring readers, locks, door contacts and exit buttons together in a four-door access controller. Ethernet connects the controller to your system, with RS485 connections for the readers.
Inside FCC4904
FCC4904 brings four door circuits to a central controller. Reader connections receive credential data; lock outputs, door contacts and exit inputs handle the door-side connections. Ethernet links the controller to the host system. Plan each door as a complete circuit before commissioning the installation.
Plan the installation
Choose around your project
Identify the reader, lock, door contact and exit button for every door. The approved reference labels four RS485 reader ports and four exit inputs.
An RS485 interface alone does not confirm reader compatibility. Confirm the reader model, firmware, protocol and cable arrangement with the selected controller configuration.
Use one of the two alternative 12 V power inputs. FIRE and TAMPER inputs are documented; their behaviour must be checked in the complete installation.
From credential to action
This is a functional outline. Use the approved wiring guide for terminal positions, then confirm the actual reader, lock and power arrangement for your installation.
A compatible reader supplies credential data to the configured access system.
The controller and host configuration determine the permitted action for the relevant door.
The door circuit uses the lock output, contact and exit input. Test each door and its feedback before handover.
Example workflow · confirm the configuration and wiring for the supplied equipment.

Shared table for single-door and four-door versions. Confirm variant, chassis dimensions and capacity before ordering or installation.
No. Credential modules, interfaces, mounting parts, network options and software can vary within the same product family. Confirm the exact model and selected options in writing before designing an enclosure, cable set or integration around it.
No. A device can have local network access without maintaining its platform or messaging connection. Check the physical network, IP settings and service connection separately, using the indicators or logs available for the selected system.
Identity verification, access permission and the physical control output are separate parts of the workflow. Have a qualified installer check the operating mode, permission result, relay timing, controller output and lock wiring against the installation instructions.
