烟雾探测器 3D模型

Description: A high poly detailed model of a Smoke Detector Textures: No texture just diffuse color. Background models on the renders are not included on this model. Its for render purposes only. History: A smoke detector is a device that detects smoke and issues a signal to a fire alarm system, or issues a local audible and/or visual alarm from the detector itself.A household smoke detector will typically be mounted in a disk-shaped plastic enclosure about 150 millimetres (6 in) in diameter and 25 millimetres (1 in) thick, but the shape can vary by manufacturer. Most smoke detectors work either by optical detection (photoelectric) or by physical process (ionization), but some of them use both detection methods to increase sensitivity to smoke. Smoke detectors are usually powered by battery; some are connected directly to power mains, often have a battery as a power supply backup in case the mains power fails.The smoke detector is one of three items of fire safety apparatus which are both recommended for homes and can be selF installed by the consumer. The second is a fire extinguisher, and the third is a fire blanket.
