2N® Helios Force

The Most Robust Door Guard for an Analogue Environment

The 2N® Helios Force door intercom guarantees reliable security for building entrances and, with the help of an analogue telephone line, clear communication with visitors. It provides the maximum possible coverage available on the market in accordance with the IP65 standard, thanks to which it is resistant not only to bad weather, water and dust, but also mechanical damage, including vandalism. It is therefore suitable as an analogue solution for door communication especially in places where there is a high demand for robustness and security for entry doors, e.g. in an industrial environment or prison.

Product highlights:

The 2N® Helios Force intercom comes with one integrated switch to control the door lock, for instance, while an extra switch may also be added to control other devices.
