Battery Powered Self-Adjusting OSID Linear Smoke Detector Emitter. Allows you to install the OSID detector emitter without the need for additional cabling. Designed, manufactured and certified according to standard EN54-12. 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. Capable of completely discriminating 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 through internal batteries. Degree of protection IP44. Operating temperature between -10 ° C and 55 ° C. Dimensions: 208 x 136 x 96 mm.
