VdS Certifies Yokogawa DTSX1 Fiber Optic Heat Detector for EN 54-22

Amersfoort, The Netherlands - March 6, 2020

VdS, in Germany, has certified the Yokogawa DTSX1 Fiber Optic Heat Detector for EN 54-22 under approval No. G 220001. The European Standard EN 54-22 applies to resettable line-type heat detectors consisting of a sensing element using a fiber optic cable, for use in fire detection and fire alarm systems installed in and around buildings and other civil engineering works.

The Yokogawa DTSX1 fiber optic heat detector, an OpreX™ Field Instruments heat sensing and fire detection solution, is housed in an enclosure and suitable for use with Yokogawa-specified fiber optic cables. The DTSX1 is a cost-effective all-in-one facility monitoring and fire detection solution that is easy to install. It is expected that this solution will aid in the timely identification of maintenance issues and thereby improve plant uptime and reduce maintenance costs. The DTSX1 Fiber Optic Heat Detector is designed to withstand the effects of dust, corrosion, heat, smoke, vibration and exhaust gases in industrial environments.


Development Background
Due to ageing facilities, labour shortage related safety management issues, and various other problems, the risk of fire is always a concern at industrial facilities, and there is a growing need for heat detection solutions. With the ability to measure the temperature distribution and to pinpoint anomalies along the entire length of a fiber optic cable, fiber optic heat detectors are an excellent solution to such issues and fiber optic solutions are increasingly used for temperature monitoring at a broad range of facilities.

Product Features 
Cost-effective and easy-to-install all-in-one solution. All DTSX1 components, including an easy-to-read display, relay output circuits, alarm circuits, and other hardware required for heat detection, are housed in a single enclosure measuring 50 cm (W) × 50 cm (H) × 25 cm (D). This small footprint is wall-mountable. The DTSX1 is easy to install, takes less time to install*1, and costs less than a general-purpose fiber optic temperature sensor.

Along the length of the fiber optic sensor cable up to 1,000 alarm zones can be defined. In total, you can connect 4 fiber optic sensor cables with a length of up to 10km*2 each. The high-performance DTSX1 has a measurement period of only 5 seconds for each fiber.
