Fire protection retroreflective sensor
Описание
It is essential that fire is not allowed to spread in buildings should it break out. Fire protection regulations therefore prescribe fire barriers. These include fire doors, industrial fire doors and fire dampers, which are generally kept closed at all times. In areas where doors are left open, such as heavily traveled passageways and corridors, a self-closing mechanism must be automatically triggered in case of fire. However, the door must not close when persons or objects are in the closing area. Legislation consequently requires monitoring with appropriate safety devices. The technical challenge is to ignore the smoke and at the same time reliably detect objects in it. These certified photoelectric sensors fulfill this function. Compact fire protection photoelectric sensor for safety devices on fire barriers, Approval in accordance with VdS Test Report FSA and externally monitored manufacture (Ü Symbol), Not sensitive to ambient light, even with switched energy saving lamps, Housing: Plastic ABS, Light type: modulated visible red light , 660 nm, Operating voltage: 12 .. 240 V AC/DC, Signal output: Relay, 1 alternator, Degree of protection: IP67fa
