Honeywell Pro4000 Series Controllers, including the Pro4000-2D (2-door) and Pro4000-4D (4-door) models, are advanced access control systems designed to deliver robust security and seamless integration for medium to large-scale facilities. Both models support multi-format readers, including Wiegand, RS-485, and OSDP, with the Pro4000-2D accommodating up to 4 readers and the Pro4000-4D up to 8 readers. These controllers feature Ethernet (TCP/IP) and RS-485 connectivity with secure TLS 1.2 encryption, enabling reliable communication across distributed networks. The systems are UL 294, CE, FCC Part 15, RoHS, and WEEE certified, ensuring compliance with global safety and environmental standards. With a database capacity of up to 100, 000 cardholders and 50, 000 events, they support multi-factor authentication, anti-passback, and anti-tailgating for enhanced security. Integration with Honeywell’s WIN-PAK and Pro-Watch, along with third-party BMS, intrusion detection, and CCTV systems, makes them ideal for scalable, enterprise-level deployments. Featuring configurable inputs and outputs, automated firmware updates, and reader port compatibility with modern tamper-proof OSDP communication, the Pro4000 series delivers unmatched reliability and performance for critical access control needs.
