Key points:
Door Capacity: It is the largest controller in the series, managing access for four separate doors.
Reader Support: It supports up to eight connected readers (four for entry, four for exit) when using RS485 terminals, or four readers using Wiegand terminals (typically one-way entry only).
High-Level Features: It includes advanced access control features like Anti-Passback and Interlocking (a feature it shares with the Ingressus II).
System Integration: Like other Ingressus models, it centralizes control, processes credentials (fingerprint, card, password) from connected terminals, stores up to 100,000 transactions, and communicates with the central Ingress software via TCP/IP or RS485.
