Aiphone AX-248C Central Exchange Unit for 24 Doors/Subs, 8-Masters

Optimize multi-point entry monitoring with the Aiphone AX-248C Central Exchange Unit, engineered for integrators and facility managers who need reliable, scalable intercom control. As the backbone of the Aiphone AX series intercom central exchange units, the AX-248C manages calling and communication for up to 8 master stations and 24 door/sub stations while supporting audio/video and audio-only connections over homerun CAT-5e with RJ45 jacks. The CEU delivers essential security and surveillance features — selective door release outputs, video and DVR trigger outputs, plus CO line transfer — enabling tight integration with access control and monitoring systems. Power is applied via redundant 24V DC inputs (two PS-242UL supplies supported), and system configuration or remote monitoring is handled through the serial interface and supplied software. Housed in a durable metal chassis that fits desk, rack, surface or wall mounts, the AX-248C reduces installation time and centralizes management for commercial, residential, healthcare or education environments. For integrators looking to expand or streamline security and surveillance deployments, the AX-248C offers a robust, configurable platform—contact your Aiphone supplier to configure and order.
