Why Yokogawa’s DTSX™1 Is the Right Solution for Demanding Fire Protection Applications**
In many industrial and infrastructure environments, conventional point‑type fire detectors quickly reach their limits. Long distances, harsh ambient conditions, and hard‑to‑access areas make reliable fire detection a real challenge. This is exactly where the DTSX™1 fiber optic heat detector from Yokogawa comes into play. As a resettable linear heat detector certified according to DIN EN 54‑22, it enables early, precise, and continuous temperature monitoring over many kilometers – with no blind spots.
Typical Fire Safety Challenges – and How the DTSX™1 Solves Them
1. Overheating and smoldering fires in cable trays and service tunnels
Cable trays and service tunnels in industrial plants, data centers, and infrastructure facilities represent a significant fire risk. Overheated cables, loose connections, or insulation damage often cause gradual temperature increases that point‑type detectors fail to detect in time.
The DTSX™1 addresses these challenges by offering:
- continuous temperature measurement along the entire fiber optic cable
- meter‑by‑meter hotspot localization
- reliable fire detection over distances of up to 16 km per channel
This allows critical temperature developments to be identified at a very early stage – well before a fire breaks out.
2. Fire risks in tunnels, underground parking garages, and transport infrastructure
Road tunnels, rail tunnels, metro systems, and parking garages subject fire detection systems to extreme conditions such as dirt, humidity, vibration, and long monitoring distances. Traditional sensors often struggle under these conditions.
The DTSX™1 is specifically designed for such environments:
- certified according to DIN EN 54‑22 and approved by VdS
- robust fiber optic sensing cables with no electrical components in the field
- redundant system design options to ensure continued monitoring even if a cable is damaged
As a result, the DTSX™1 is ideally suited for mission‑critical fire protection applications where maximum reliability is essential.
3. Early detection of thermal abnormalities in conveyor systems and industrial processes
Conveyor belts, bulk material handling systems, and industrial production lines present a high risk of heat‑related incidents. Blocked rollers, bearing failures, or hot transported materials can remain undetected for long periods and often lead to fires or unplanned downtime.
With the DTSX™1, operators benefit from:
- continuous temperature monitoring along the entire conveyor route
- freely configurable alarm zones and temperature thresholds
- easy integration into fire alarm and control systems via standard interfaces such as Modbus TCP/IP
This makes the DTSX™1 not only a fire detection solution, but also a powerful tool for preventive maintenance and operational safety.
Technology and Key Benefits at a Glance
The DTSX™1 uses fiber optic Distributed Temperature Sensing (DTS) technology, where a single fiber optic cable acts as a continuous temperature sensor along its entire length.
Key advantages include:
- resettable linear heat detector compliant with DIN EN 54‑22
- VdS‑approved (e.g., classes A1N, A2N, BN, CN)
- precise localization of temperature events with high spatial resolution
- long monitoring distances with minimal maintenance requirements
This makes the DTSX™1 particularly suitable for large‑scale and safety‑critical applications where conventional heat detectors are insufficient.
Conclusion: Greater Safety Through Linear Heat Detection
Whether in tunnels, cable trays, or industrial conveyor systems, the DTSX™1 from Yokogawa provides a reliable, certified, and proven solution for demanding fire protection tasks. By combining fiber optic sensing technology with long monitoring ranges and precise localization, fires and thermal anomalies can be detected early and addressed effectively.
