Aiphone TD-24H/B 24-call Wall Mount Audio Intercom

Product Description

The AIPHONE TD-24H/B is a 24-call wall-mount audio intercom master station designed for multi-station intercom systems in residential and commercial installations. This unit handles call signaling and two-way audio communication across up to 24 stations, making it a practical choice for facilities that require organized, centralized call management without video. It mounts directly to a wall surface and is sold as a single unit. Electricians and low-voltage communication technicians are the primary trades responsible for installation and commissioning.

The TD-24H/B is suited for office buildings, schools, apartment entry systems, healthcare facilities, and similar environments where audio-only intercom coverage across multiple call points is required. Its 24-call capacity supports larger installations where a single master station must manage calls from numerous substation or door units within the same AIPHONE system.

Installation Notes

Installation is typically performed by a licensed low-voltage or communications electrician in accordance with NEC Article 725 for Class 2 and Class 3 remote-control and signaling circuits. Power down the intercom system at the power supply before making any wiring connections. Follow AIPHONE system wiring diagrams precisely for station addressing and bus connections.
