eSSL-Access-8004 – 4‑Door Multi Door Access Control System
The eSSL-Access-8004 multi door access control system is a compact, high‑performance IP controller designed for 4 doors. It combines 20,000 card capacity, 100,000 event logs, dual‑door management, advanced anti‑passback and interlock, and real‑time PC monitoring – making it the ideal choice for offices, manufacturing facilities, residential towers and institutional campuses.
The eSSL-Access-8004 forms the core of a robust multi door access control infrastructure for mid‑sized and large premises. By connecting up to four Wiegand 26/34 readers, it gives you full two‑way access control while logging every event from a -40°C to +70°C operating range. With 256 time zones, 256 access levels, anti‑passback, interlock, multi‑card opening and optional fire alarm linkage, this 4‑door controller offers the kind of advanced security normally found in much larger access control systems.
🔑 Core Multi Door Access Control Capabilities
✅ 4‑Door Control with Flexible Modes
Control up to 4 doors. Configure each door as “entry with card, exit with button” or “entry with card, exit with card” – the choice is yours.

✅ Anti‑passback & Interlock
Prevent tailgating and enforce “one‑card‑one‑entry” rules. Interlock ensures that a second door cannot be opened while the first one is open – essential for high‑security zones.
