Product classification

ANKA Sci-Tech Co.,Limited | Updated: Dec 17, 2015

Smoke alarm from sensors can be classified as Ionic smoke detectors and photoelectric smoke alarms, and so on.

Ion smoke

Ion smoke detector has an ionization chamber, ion Chamber radiation elements-americium 241 (Am241), is about 0.8 MC around under normal conditions in the electric field of equilibrium, when smoke enters the ionization chamber would destroy the balance of alarm circuit is detected when the concentration exceeds a set threshold alert will be issued.

Photoelectric smoke

Photoelectric smoke alarm has a maze of optical, infrared tube is installed, when smoke-free infrared receiver cannot receive the infrared light from infrared transmitting tubes, when smoke enters the optical labyrinth, by refraction, reflection, receiver receives the infrared light, alarm circuit judge whether it exceeds the threshold, if more than alert.
