About us

With the LIOS Sensing product line, NKT Photonics is the market leader in distributed optical sensing of temperature and strain for security, safety and fire detection.

Backed by more than 20 years of experience and thousands of systems in the field worldwide, we deliver LIOS monitoring solutions with unrivaled quality and performance.

We provide full solutions from the early design phase, over installation and commissioning, to service and maintenance when the system is deployed. Everything made in Germany under ISO 9001 and 14001 certification.

Products and services

The LIOS DE.TECT range of optical linear heat detection systems offers fast and accurate fire detection in tunnels, metros, and other large installations.

With fire detection projects in 18 different countries our DE.TECT solution has become a trusted partner with installers of fire alarm systems, constructors of extinguishing systems, and general contractors across the globe.

Since the introduction in 1997 the DE.TECT system has revolutionized the safety standard in underground transport facilities as it enabled complete and precise monitoring of an entire tunnel length with one system.

LIOS DE.TECT Linear heat Detection

LIOS DE.TECT Linear heat Detection

LIOS DE.TECT is a robust linear heat detection system based on optical fibers. With a range of up to 10 km and a sampling interval down to 25 cm, the system is ideal for fire detion in tunnels and metros as well as large facilities like warehouses and industrial facilities.

Linear Heat Detection Sensor Cables

Linear Heat Detection Sensor Cables

NKT Photonics provides the appropriate sensor cable for every application and when working with us we will help you pinpoint the exact cable design and installation appropriate for your project.
One vital component in the DE.TECT smart sensor design, is a tube that accommodates 2 optical fibers. The coating of the optical fiber can be tailored to optimally suit the required resistance to temperature conditions and mechanical impacts in your specific project.

Charon Visualization and Monitoring Software

Charon Visualization and Monitoring Software

Charon is the software that binds all sensing data together in one platform. Compatible with all LIOS sensing products and a range of third party sensors, Charon can combine data from multiple sources and store them in a common SQL database. From the database, the sensing data can be presented both visually in one big overview where you can quickly get a status on the entire installation being monitored, or split up in graphs, tables or any other format you may want.
