Linear smoke detectors
Detection through reflection
The linear smoke detector is the best choice for areas with limited access. It provides early detection of smoke-forming flaming fires in high-ceiling buildings like high-bay warehouses, atria or libraries. As these application areas have a high ceiling, point type detectors prove to be impractical. The linear smoke detector works according to the reflection principle: It sends infrared light to a reflector, which sends it back immediately. False alarms are reliably prevented with an additional distance measurement, which detects foreign bodies in the light beam – for example, if a fork lift truck should interrupt the beam. The linear smoke detector provides a flexible monitoring distance of 5 – 100 m. Moreover, it only has to be connected at one end. This means that no cable is necessary between the detector and reflector. As less cabling is needed, the linear smoke detector is a cost-efficient solution.
