What are the smart smoke alarm solutions?
Intelligent smoke alarm solution:
1. Ion smoke alarm: there is an ionization chamber. The radiation element used in the ion chamber -- americium 241(Am241), with the intensity of about 0.8 microcuries, is in the balance state of electric field under normal state.
2. Photoelectric smoke alarm: there is a optical maze, equipped with infrared tube, smokeless infrared receiving tube when not receive infrared transmitting tube infrared light, when smoke into optical labyrinth by means of refraction, reflection, receiving tube receives the infrared light, intelligent alarm circuit judge whether more than threshold, if more than an alarm.
