Product information "LA28/LK28-FC-Z/31/116"

Compact fire protection light barrier for safety systems on fire protection closures. Designed as a one-way light barrier with the longest range. Safeguards walk-through closures such as fire doors, gates, or dampers and closures in rail-bound conveyor systems. Reliable detection of people and objects for hold-open systems on fire closures, even in case of smoke development. Approved according to VdS test report FSA and externally monitored production (Ü mark). In the event of fire, smoke is ignored, but people in the smoke are reliably detected. Resistant to ambient light, even with pulsed energy-saving lamps. 

These fire protection light barriers are not smoke detectors!
