## Summary description

Grothe HT 1730/2 is a wired additional telephone handset designed for use with compatible Grothe intercom or door entry systems. It provides a simple wired connection for voice communication inside buildings, enabling residents to answer visitors at the entrance. Ideal for residential or small commercial installations where an extra internal handset is needed for convenience and clear audio between entrance and living spaces.

## Long description

Grothe HT 1730/2 is a wired additional telephone handset designed for use with compatible Grothe intercom and door entry systems. The unit is intended to extend internal voice communication points within a building, allowing occupants to answer and converse with visitors at the entrance from an extra room. The handset connects via a wired interface to the base intercom system and provides a straightforward solution for adding an internal extension without changing the existing door station or central unit.
Advantages
The additional handset offers a compact and reliable wired connection for clear voice transmission and simple operation. Its design focuses on functional compatibility with Grothe systems and ease of installation, reducing the need for complex wiring changes. The handset provides a consistent audio path and convenient internal placement for improved access to intercom functions across multiple rooms.
Suitable for
Homes where an extra indoor handset is needed for answering the entrance intercom
Small offices and retail premises requiring an additional internal communication point
Multi-room apartments to place an alternative listening/answering position
Renovation projects where adding a secondary handset is preferred over replacing the main system
Key specifications
Connection type: wired interface compatible with Grothe intercom systems
Function: additional indoor telephone handset for voice communication with entrance units
Form factor: wall-mountable/desk placement depending on installation
Audio: voice-only communication optimized for intelligibility
Controls: basic call/answer operation and handset cradle
Power: supplied through the intercom system wiring (no separate mains adapter required)
How to use
Install the Grothe HT 1730/2 by connecting it to the compatible intercom system following the manufacturer’s wiring diagram for additional handsets. Mount the unit on a suitable wall or place it on a desk where the cable reaches the system connection point. Once connected, use the handset to answer calls from the door station and speak with visitors; the device operates as an extension of the main intercom, with simple call/answer handling via the handset cradle and controls. If the system includes call transfer or multiple extension features, follow the main unit’s instructions to enable those functions for the additional handset.
Usage recommendations
The handset is intended for indoor use only; avoid exposure to moisture or direct sunlight. For reliable operation, use compatible Grothe intercom equipment and check wiring connections during installation. If unsure about wiring or compatibility, consult a qualified installer or refer to the main intercom system documentation.
