Keri Systems PXL-500WNE Access Control Main Board

Deliver enterprise-grade security and flexible site-wide monitoring with the Keri Systems PXL-500WNE access control main board. Engineered as the core of the PXL-500 Tiger II platform, this access controller scales from a single door to a 256-door network per site and supports up to 65,000 users, enabling centralized management of distributed access points while keeping intelligence at the edge. Installers and security managers benefit from modular expansion—add one or two doors at a time—to grow capacity without major rewiring or downtime, lowering total installed cost.

The PXL-500WNE includes RS-485 networking for reliable multi-site connectivity and an RS-232 port with optional TCP/IP or modem links for remote monitoring and integration with security management and surveillance systems. Five-year memory retention protects user credentials and event history for compliance and incident response. Compatibility with existing Keri PXL-250 systems makes phased upgrades seamless.

Ideal for commercial facilities, healthcare campuses, education and government installations that require robust access control, auditability and integration with surveillance and monitoring platforms.
