DTSX1 Fiber Optic Heat Detector

The DTSX1 addresses the need for maintenance to avoid accidents caused by high-temperature heat, such as equipment failures due to heat and equipment abnormalities. This product focuses on fire detection *1 applications and is also pursuing ease of introduction. Since the fiber optic sensor cable is prepared as a standard product, it is seemingly trivial, but there is no need to worry about unexpected equipment selection.
*1: Fire detection standard (EN 54-22) certificated
       VdS-approval No. G 220001
