Will smoking call the police after the smoke alarm in the hotel room is wrapped?

Smoke alarm realizes fire prevention by monitoring the concentration of smoke. The smoke alarm adopts ion smoke sensor, which is a kind of sensor with advanced technology and stable and reliable work. It is widely used in various fire alarm systems, and its performance is far superior to that of gas-sensitive resistance fire alarm. ?

It has radioactive source americium 24 1 in the inner and outer ionization chambers, and the positive and negative ions generated by ionization move to the positive and negative electrodes respectively under the action of electric field.

Under normal circumstances, the current and voltage of the inner and outer ionization chambers are stable. Once there is smoke, the ionization chamber outside will disappear quickly. If the normal motion of charged particles is disturbed, the current and voltage will change, which will destroy the balance between the inner and outer ionization chambers. So the wireless transmitter sends out a wireless alarm signal to inform the remote receiving host and send alarm information.

Practical significance:

The "smoke alarm" consists of two parts: one is an induction sensor for detecting smoke, and the other is an electronic speaker with very loud sound, which can remind people in time once danger occurs.

In order to maintain the normal operation of the smoke alarm, only a 9 volt battery is needed. At present, the most widely used smoke alarms in the world are photoelectric smoke alarms and ionization smoke alarms.

On the characteristics of family fire and fire prevention countermeasures;

It is of practical significance to prevent family fires and reduce fire losses. In modern urban families, many people don't know the common sense of family safety and cause fire accidents, which destroy a happy family in a blink of an eye, and some even lead to family destruction and death. Moreover, in the event of a family fire, improper handling and slow alarm are the main causes of casualties.

Therefore, people should actively understand the main causes of family fires, master the knowledge of fire prevention and the methods to protect themselves in case of fire, and eliminate fires in time.

There are more than 50,000 serious family fires in Britain every year, most of which cause casualties and huge family property losses, and some even involve neighbors, and the fire losses are more serious.

When investigating the cause of the fire, most of the parties in the fire family said that they always thought that the fire was someone else's business and was far away from themselves, but they didn't expect it to happen to themselves this time.
