Our solution is thoroughly tested and certified(VdS EN 54-22, UL521, ULC S530, FM 3210, ATEX II(1) GD M2, KFI, CCC, SIL2) with the industry's fastest fire detection and lowest false alarm rate. Our Distributed Temperature Sensing (DTS) system detects fires precisely and can accurately track the size and direction of a spreading fire, regardless of air currents. No other fire detection system can withstand temperatures up to 750 °C (1382 °F) without losing monitoring capabilities. With this unique feature, fire-fighting countermeasures can be used effectively during the fire event. Our solution also includes certified and maintenance-free sensor cables to fit your requirements.

The fiber optic-based LHD has multiple advantages in comparison to conventional fire detection systems or non-fiber optic LHD. One single passive fiber covers a long range up to 10 km, whereas traditional solutions would need many sensors as well as individual systems. The high sampling interval is less than one meter, which permits quick activation of countermeasures in an emergency situation. Because of its low laser power, AP Sensing’s LHD is well-suited for hazardous environments such as those found in chemical plants, coal storage facilities, mining conveyor belts, or other facilities requiring ATEX/IECEx certification. It is easy to integrate into existing fire alarm systems and can be utilized either as an alternative or an enhancement to existing fire detection systems. LHD enables early identification of rate of heat rise, and therefore detects heat abnormalities earlier than other technologies, with discrete trigger points at a higher temperature. Based on temperature delta, our LHD system differentiates between fire and temperature increases due to seasonal changes. Thanks to the distributed fiber optic technology, linear heat monitoring enables gapless monitoring and complete asset coverage.
