A small fire detector in Cycles.
Everything has a Subdivision Surface Modifier, so you can decrease or increase the level of detail.
The base model has 830 vertices and 386 faces. With low SSM settings you get approx. 7000 vertices and 6500 faces. With high settings (as used for the first render) you get approx. 98.500 vertices and 96.500 faces.
Feel free to use it for whatever you like - to use it in your own project just Link/Append the group "fire-detector".
