The CD290 high-performance smoke detectors produced by Sentek are designed for fire detection of environment with some dust and water vapor.The detector adopts the newly developed red/blue double-beam detection chamber of the Sentek, According to the Mie scattering theory, the smoke particle size in the aerosol produces different scattering effects on the red/blue light, and generates different electrical signals through the internal circuit of the product. The sophisticated processing of the software further differentiates the size of the particles in the aerosol to determine the true smoke aerosols and non-smoke aerosols.
The product has high sensitivityto fire smoke, has strong anti-interference ability to non-fire aerosols (water vapor, dust,fiber, etc.), it can compensate for detector pollution caused by environmental pollution, and reduces the probability of false alarms. The detector has quick response to smoke, low false alarm rate and long maintenance cycle (maintenance costs less),it is an ideal detector to replace normal smoke detector.
