Aiphone TD-3H/B 3 Call Wall Mount Intercom

Product Description

The AIPHONE TD-3H/B is a 3-call wall mount audio intercom station designed for use in audio-only intercom systems. This unit mounts directly to a wall surface and provides three-call selection capability, allowing communication across multiple points within a facility. It is a master or sub station component in a wired audio intercom network and is typically installed by licensed electricians or low-voltage communication technicians.

It is designed for wall-mounted deployment in environments such as offices, multi-tenant buildings, schools, or access-controlled entry points where a compact, multi-call intercom station is needed. Installation is completed by a low-voltage or communications contractor familiar with intercom wiring standards.
