Project Highlight | JR101-FK Installed in UK Subsea Tunnel (Silvertown)

We're proud to share another successful installation of our JR101-FK waterproof emergency telephone - this time in the Silvertown Subsea Tunnel, UK, a major infrastructure project supported by Indra Sistemas, S.A.

Designed for harsh environments like tunnels and offshore applications, the JR101-FK has once again proven its durability, clear audio performance, and IP-rated waterproof design in real-world conditions.

To make this collaboration even more meaningful, our engineers were specially invited on-site by the client for a firsthand inspection and discussion - an opportunity that strengthens trust and technical integration.
