## Summary description

The ZKTeco GL-C3-PRO400 is an access controller designed for electronic access control systems. As a door/entry controller it integrates with readers and locking hardware, supporting centralized management of user credentials and door events. Suitable for offices, small-to-medium buildings and secured entry points where networked access control and event logging are required.

## Long description

The ZKTeco GL-C3-PRO400 is a networked door controller intended for electronic access control systems. It acts as the central unit that connects card or biometric readers, electric locks and alarm inputs to a building’s access management software. The controller supports centralized credential management, event logging and real-time door status monitoring, making it suitable for offices, small-to-medium buildings and secured entry points that require networked access control and audit trails.
Advantages
The device provides reliable integration between readers and locking hardware over a network, allowing centralized configuration and monitoring of multiple doors. It records and stores door events for audit purposes and supports real-time status reporting to management software. Designed for indoor installation, the controller offers a compact footprint and straightforward wiring for common access control setups.
Suitable for
Office buildings and administrative areas
Small-to-medium enterprises with multiple controlled doors
Server rooms, storage areas and secured entry points
Locations requiring event logging and centralized access management
When it may not be suitable
This controller is intended for integration into IP-based access control systems and may not be appropriate for fully standalone, offline installations that require no network connectivity. For very large scale deployments with hundreds of doors, a solution explicitly designed for high-density enterprise environments may be more appropriate.
Key specifications
Function: networked door/entry controller for access control systems
Interfaces: connections for readers, lock outputs, alarm inputs and network (Ethernet)
Management: supports centralized credential administration and event logging
Monitoring: real-time door status reporting to management software
Installation: indoor mounting, compact size suitable for standard control enclosures
How to use
Install the controller in a secure indoor location near the protected door and connect readers, electric lock, request-to-exit and alarm inputs according to the wiring diagram provided by the installer. Connect the device to the local network via Ethernet and register it in the access management software to configure users, access levels and schedules. Verify reader operation and test lock release and alarm inputs; monitor event logs from the central software to confirm proper operation.
What to consider before purchase
Ensure compatibility with the chosen card or biometric readers and locking hardware
Confirm network infrastructure and IP addressing for device integration
Check indoor mounting space and wiring access near the protected door
Plan software and user management requirements for centralized control
Usage recommendations
For reliable operation, use the controller with compatible readers and locking devices, maintain a stable network connection, and perform regular backups of access control configurations and event logs. Periodic verification of door sensors, power supply integrity and firmware updates will help maintain secure and predictable access control performance.
