Fire protection sensors
In the event of a fire in a building or plant, fire barriers such as fire doors, gates and dampers help prevent the spread of fire and smoke in corridors, aisles and shafts. A reliable automatic closing mechanism is critical in this regard.
Fire doors serve as safety devices for locking systems on fire accounts. Normally they are open and close in case of fire. Fire Protection Sensors ensures that the closing edge will close only in the case if no obstacles in the closing area.
For fire protection gates, the Sensotek line includes specially certified and approved light barriers. These are for use in fire protection doors, gates and shutters which normally remain open, but must be closed in case of fire.
The German fire protection regulations require monitoring with appropriate safety systems. The technical challenge is to reliably detect people in smoke filled areas, despite the influence of any smoke build-up. This function is fulfilled by the fire protection light barriers by Sensotek.
In the range of the sensors for fire protection light barriers there are two different principles of operation:
- Thruw-beam fire light barrier
- Fire protection reflection light barrier with polarization filters
