Private Handset Communication

The DA-1MD uses a traditional telephone-style handset for private communication between the tenant and entrance station.

Unlike an open-voice speaker station, the handset provides full-duplex conversation, allowing both parties to speak naturally without requiring push-to-talk operation.

This makes the DA-1MD well suited for:

• Apartments

• Condominiums

• Offices

• Small multi-tenant buildings

• Controlled commercial entrances

DA Series System

The Aiphone DA Series is a simple audio entrance system designed for:

• 1 entrance

• DA-4DS – 4-Call Audio Entrance Station

Each entrance call button is assigned to the appropriate tenant station.

Door Release

The DA-1MD includes a dedicated door-release button.

When pressed during a visitor call, the compatible DA entrance station can provide power to the electric door strike.

Aiphone specifies compatible locking hardware such as:

EL-12S – 12V AC/DC Electric Door Strike

The DA Series door-release output is designed for a lock rated approximately:

9.5–20VAC, 70 Ohms or higher resistance

Always verify the connected locking-device requirements before installation.

Service / Option Button

The DA-1MD includes a service button that can be used to control a compatible external device.

Possible applications can include:

Additional interface equipment may be required depending on the device being controlled.

A visual indicator shows when the call tone has been muted.

15VAC

Aiphone specifies the:
