LIOS DE.TECT Linear Heat Detection

The LIOS DE.TECT range of optical linear heat detection systems offers fast and accurate fire detection in tunnels, metros, and other large installations.
 

With fire detection projects in 18 different countries, our DE.TECT solution is trusted by installers of fire alarm systems, constructors of extinguishing systems, and general contractors across the globe. Since the introduction in 1997, the DE.TECT system has revolutionized the safety standard in underground transport facilities by enabling precise monitoring of an entire tunnel length with one system.
