Al Rayyan Cable Tunnel Protection

The Public Works Authority of Qatar required a reliable monitoring solution for several new electrical cable tunnels. The solution must function alongside other monitoring technologies and interface with the local Fire Alarm Control Panel (FACP). Six AP Sensing Linear Heat Detection (LHD) devices were selected for this project.


AP Sensing's solution is ideal for electrical cable tunnels, as the fiber optic cable itself is small, lightweight and easy to install - fitting the twists and turns of a tunnel. As the project location is typically hot and humid year-round, engineering reliability was also a requirement. 

The project was commissioned in stages, and some of these tunnels have now been protected with fiber optic LHD since 2016.
