Self-adjusting OSID linear smoke detector emitter powered at 24 V. Designed, manufactured and certified according to EN54-12 standard. Linear detector based on transmission of infrared and ultraviolet rays, captured by a receiver with image detection. This type of technology allows OSID linear detectors a high immunity against structural movements. Able to completely discriminate smoke from dust or water vapor, due to the attenuation caused by these elements differently on both wavelengths (UV and IR), which makes them ideal detectors against adverse environmental conditions in the installation. Automatic alignment assisted by laser pointer and facilitated by the rotating head. Working voltage from 20 to 30 V. Consumption: 350 uA. Degree of protection IP44. Operating temperature between -10 ° C and 55 ° C. Dimensions: 208 x 136 x 96 mm.
