How to clean the smoke detector in the fire fighting system of the engine room?
Smoke can be twisted down, the general is to remove the dust cover, please professional companies, their professional point is to use carbon tetrachloride, such as cleaning, there may be oil, etc.!
It inside and outside the ionization chamber inside the radioactive americium 241, positive and negative ion generation, under the electric field respectively to the positive and negative electrode movement. 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.
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.
