LIOS DE.TECT Linear Heat Detection

LIOS DE.TECT is a robust linear heat detection system based on optical fibers. With a range of up to 10 km and a sampling interval down to 25 cm, the system is ideal for fire detion in tunnels and metros as well as large facilities like warehouses and industrial facilities. In addition, the fiber optic system is well suited for hazardous environments such as those found in chemical plants, coal storage facilities, mining conveyor belts, or other facilities requiring ATEX certification. LIOS DE.TECT offers fast, accurate and reliable linear heat detection in any environment.

The LIOS DE.TECT linear heat detection system is easy to integrate in fire management systems. It can be configured with one, two or four channels each providing up to 10 km range (6 km for a four channel configuration).

Each channel has 1000 programmable zones that can all be set up with individual alarm and pre-alarm criteria for highly granular and precise fire detection. Combined with the high sensitivity and fast response time, this ensures quickest possible fire detection and precise localization of the source.

A linear heat detection system must meet the highest requirements for reliability and in this regard, the DE.TECT system is exceptional. The controller has no moving parts, it is immune to electromagnetic disturbances, and it has an MTBF of more than 30 years, ensuring reliable fire detection in even the toughest environments.

With thousands of LIOS linear heat detection systems installed Worldwide, the DE.TECT system is the standard within linear optical heat detection and the system behind the successful FibroLaser fire detection equipment from SIEMENS.
