## Summary description

ZKTECO GL-C3-PRO400 is an access controller designed for single-door access control installations. It operates as a networked controller providing centralized management of door entry, suitable for integration with card readers and electric locks. Typical uses include small offices, retail premises and residential buildings requiring controlled entry and event logging.

## Long description

The ZKTECO GL-C3-PRO400 — single-door networked access control unit is a network-capable controller designed to manage one door with centralized logging and remote configuration. It supports integration with standard card readers and electric locking mechanisms, providing basic access control functions for locations that require authorized entry and audit trails. The unit connects to a network for real-time status updates and event recording and is intended for straightforward single-door installations.
Advantages
The controller offers network connectivity for centralized management and real-time event reporting, enabling remote administration and monitoring. It supports common reader interfaces and standard locking outputs, which simplifies integration into existing systems. Its single-door focus reduces complexity for small-scale deployments while still providing reliable logging of access events and straightforward power and communication wiring.
Suitable for
Small offices and administrative rooms requiring one controlled entrance
Retail premises with a single staff entrance or back-office door
Residential buildings or gated units where one controlled access point is sufficient
Server closets or equipment rooms that need logging and restricted entry
When it may not be suitable
This single-door controller is not intended for multi-door or large-scale access control deployments where centralized multi-door coordination, advanced anti-passback across many points, or high-availability failover is required. Installations that require embedded biometric processing or on-device user databases for dozens of doors may be better served by multi-door controllers or a different product family.
Key specifications
Supported doors: single-door controller configuration
Connectivity: network interface for centralized management and event reporting
Reader interfaces: standard card reader input compatibility
Lock control: electric lock output and auxiliary relay for door release
Event logging: local event recording with network transmission to management software
Power: local power input and standard power supply requirements for access controllers
How to use
Mount the unit near the controlled door according to installation guidelines, connect the electric lock, reader, and request-to-exit devices to the appropriate terminals, and provide a power connection. Configure network parameters so the controller communicates with the chosen management software, then register readers and enroll access credentials through the management interface. After configuration, use the software to assign access levels, schedules, and to review event logs for auditing.
What to consider before purchase
Ensure the unit supports the reader types you plan to use and that wiring distances comply with installation limits
Confirm network compatibility with your existing infrastructure and management software requirements
Verify power supply specifications and whether an external power source or battery backup is needed
Assess whether a single-door controller meets future expansion plans or if a multi-door system would be more appropriate
Usage recommendations
For reliable operation use the controller with compatible ZKTECO management software or third-party platforms that support networked access controllers. Keep firmware updated, use a stable network connection, and implement a backup power solution for uninterrupted access and logging.
