eSSL C3-400
eSSL C3-400 – Four Door Access Control Panel with Browser Management
eSSL C3-400 is a powerful four-door access control panel that manages up to four entry points simultaneously from a single controller board. As part of ESSL's enterprise essl access control system range, the C3-400 is built on open, flexible technology with browser-based management—requiring no additional client software installation.
The C3-400 stores 30,000 card holders and 1,00,000 event logs, communicates via RS-485 and TCP/IP, and supports interlock, multi-card operation, anti-passback, and duress mode. CE, FCC, and RoHS certified, it integrates seamlessly with CCTV, fire alarm, and BAS systems via its 12 input and 8 output ports. An SDK is available for custom integrations.

Frequently Asked Questions – eSSL C3-400
How many doors can eSSL C3-400 control?
The C3-400 controls up to 4 doors simultaneously from a single panel, with 4 Wiegand reader ports and 4 relay outputs for electric locks.
Does C3-400 require client software?
No. The C3-400 uses a browser-based (B/S structure) management interface accessible from any PC on the network via IE/browser—no client software installation is required.
What security functions does C3-400 support?
The C3-400 supports interlock (one door open = others closed), multi-card operation (multiple cards required to open high-security doors), anti-passback, and duress mode.
Can C3-400 integrate with CCTV and fire alarms?
Yes. The C3-400's 12 input ports can connect to CCTV triggers, fire alarms, smoke detectors, and BAS systems for a complete integrated security solution.
Is an SDK available for eSSL C3-400?
Yes. ESSL provides an SDK (Software Development Kit) allowing system integrators to embed the C3-400 into existing access control software or develop new applications.
