Why smoke smoke detector why flash?
Under normal conditions, the internal and external ionization chambers are stable in both current and voltage. Once a smoke Cuantao outside the ionization chamber. Interfere with the normal movement of charged particle current, voltage will change, destroy the balance between internal and external ionization chamber, and a wireless transmitter sends wireless alarm signal to the receiving host notification from afar, the alarm message.
Smoke detectors are flashing because the electric current generated by charged particles in the smoke detector passes. Inside and outside the ionization chamber smoke inside radioactive americium 241, positive and negative ion generation, under the electric field respectively to the positive and negative electrode movement.
The smoke detector is by monitoring the concentration of smoke to achieve fire prevention, smoke detectors, the internal use of ion smoke sensor, ion smoke sensor is a kind of advanced technology, stable and reliable operation of the sensor, is widely used in all kinds of fire alarm system, fire alarm performance is far better than the gas sensing resistance type.
