The Aiphone DA-4DS + 4× GT-1D Intercom Kit is a professional multi-tenant audio entry system designed for apartments and commercial buildings.

Product Description

The Aiphone Intercom Kit combines the durable Aiphone DA-4DS 4-button audio door station with 4 × Aiphone GT-1D audio tenant handsets, delivering a complete multi-tenant entry communication solution for residential and commercial properties.

Designed for apartment complexes, condominiums, and professional suites, this system enables secure visitor screening and remote door release functionality. Visitors call individual tenants directly from the mechanical button panel, and residents answer using the telephone-style handset for private, clear audio communication.

The DA-4DS provides vandal-resistant silver metal construction and dry contact lock output, while the GT-1D tenant stations offer intuitive pickup-to-answer operation, door release control, and security/concierge call functionality. The GT-1D units are powered via the GT-BC bus controller (24V DC), supporting scalable deployment in multi-unit buildings.

This kit is ideal for buildings requiring reliable, audio-only communication with straightforward installation and long-term durability.
