Intercom Handset CYFRAL SMART 5P for Analog 4+N Systems, white-grey

CYFRAL SMART 5P is an intercom handset designed for analog 4+N door entry systems. Finished in white-grey, the SMART 5P functions as an internal unifon that provides two-way voice communication with an external door panel and enables basic call handling in multi-tenant residential or small commercial installations. The device connects to standard 4+N wiring and is intended where straightforward, reliable audio intercom capability is required without additional video or advanced access-control features.

Advantages

The handset offers a compact, wall-mounted design that simplifies installation on existing 4+N analog circuits and reduces the need for rewiring. Its user interface is intentionally minimal to ensure easy operation: answer and talk functions are accessible without complex menus. Built for routine daily use, the unit provides clear voice transmission suitable for door communication and call management in buildings with standard intercom infrastructure.

Suitable for

• Residential apartment buildings with analog 4+N door entry systems
• Small office premises requiring basic internal voice intercom
• Replacement or upgrade of existing unifons on 4+N wiring
• Properties where a compact, wall-mounted audio handset is preferred

How to use

Mount the handset on a suitable wall location near the entrance or within an apartment following the manufacturer’s mounting instructions.
