It is just more and more prominent." fire preventing and the harm for reducing fire " is the general overview to fire-fighting legislation meaning, includes two layers
Meaning：First, carrying out the work in every of fire preventing, prevent fire；Second is that fire is absolutely not impossible, and
Once occur fire, just should in time, be effectively performed and put out a fire to save life and property, reduce the harm of fire.
Ion smoke alarm is there are one ionisation chamber, radioactive element -- americium 241 (Am241) used in ion chamber, intensity about 0.8
Micromicrocurie or so is in the equilibrium state of electric field under normal condition, this equilibrium relation can be destroyed when there is flue dust to enter ionisation chamber,
Warning circuit detects can send out alarm when concentration is more than the threshold value of setting.
There are one optics labyrinths in photoelectric mist alarm, are equipped with infrared tube, infrared receiving tube can not receive when smokeless
The infrared light that infrared transmitting tube is sent out, when flue dust enters optics labyrinth, by reflecting, reflecting, reception pipe receives infrared light,
Whether intelligent alarm circuit judges are more than threshold value, if it exceeds sending out alarm.
The work of both the above smoke alarm has some defects, ion smoke alarm to when the particle in smog compared with
Small comparison is sensitive, and the smog generated when smouldering fire causes fire cannot timely enter ion-conductance room, while the smog generated
Particle is larger, will result in failing to report or the case where evening paper, causing and miss best fire extinguishing period for ion smoke alarm.Light
Electric smoke alarm pair compared with the reaction of the bulky grain in smog promptly and accurately, but when fire is initial is detected region
When interior smoke particle concentration deficiency, when have extension on the time that many smog enter optics labyrinth, cause evening paper the case where,
And will produce the phenomenon that wrong report when the koniology of working environment is larger, to there is certain requirement to working environment.
