Aiphone AX-320C Add-On Exchange Unit for 32-Doors/Subs

Scale your access and monitoring infrastructure with the Aiphone AX-320C add-on exchange unit — a purpose-built intercom central exchange unit designed to expand AX systems up to 32 doors/substations. As the AX system wiring hub, the AX-320C uses CAT-5e connectivity and four RJ45 master station ports to simplify cabling and centralize communications, making integration with security and surveillance systems faster and more cost-effective.

The AX-320C controls core intercom functionality, supports a programmable door release (24V AC/DC dry contact, 500mA) and fits neatly in a 19" EIA 2U rack or on a wall for flexible deployment. With a door-to-exchange distance of up to 980', it supports medium- to large-site layouts common to corporate campuses, education, healthcare and multi-tenant buildings. NDAA and TAA compliance ensure suitability for public sector projects.

Choose the Aiphone AX-320C when you need reliable, wired connectivity for scalable access control, secure site monitoring and streamlined installation. Contact your systems integrator or Aiphone dealer to configure this unit for your next security or surveillance deployment.
