磁性烟雾报警器固定座

Smoke detector is a common fire protection device which can sense the smoke in the early stage of fire and thus provide early warnings to people promptly.烟雾探测器是一种常见的消防设备,可以在火灾早期感知烟雾,从而迅速向人们发出预警。 Generally, fire development process can be divided to the initial stage, development stage, and attenuation stage.通常,火灾的发展过程可分为初始阶段,发展阶段和衰减阶段。 The common principle of the smoke detector is to avoid the fire through the smoke concentration detection.烟雾探测器的通用原理是通过烟雾浓度检测来避免火灾。 The production of smoke is earlier than visible and invisible light when substance burns, and smoke detector can capture the early signals of fire, then signals will be transmitted to the controller of automatic fire alarm system after converted into electrical signals.物质燃烧时,烟雾的产生要早于可见光和不可见光,并且烟雾探测器可以捕获火灾的早期信号,然后将信号转换为电信号后,将其传输到自动火灾报警系统的控制器。 Smoke detector also hastens a lot of demand for the magnetic smoke detector mount.烟雾探测器还增加了对磁性烟雾探测器安装架的需求。

Smoke detector can be classified into ionization type and photoelectric type.烟雾探测器可分为电离型和光电型。 For ionization smoke detector, positive and negative ions producing by ionization of对于电离烟雾探测器,通过电离产生正离子和负离子 Am-241来源 will move towards the positive and negative electrode under the action of the electronic field, respectively.会在电场的作用下分别向正极和负极移动。 Current and voltage of both internal and external ionization chamber are stable under normal conditions, but these two electrical parameters would be changed when smoke enter into the external ionization chamber, then undermine the balance between internal and external ionization chamfer, thus detector will transmit the alarm messages.在正常条件下,内部和外部电离室的电流和电压均稳定,但是当烟雾进入外部电离室时,这两个电气参数会发生变化,从而破坏内部和外部电离倒角之间的平衡,因此探测器将发出警报消息。 Photoelectric smoke detector is composed of light source, photoelectric element, and electronic switch.光电烟雾探测器由光源,光电元件和电子开关组成。 The light emitted by the luminous element will pass to photosensitive element and circuit maintains normal work.发光元件发出的光将通过光敏元件,电路保持正常工作。 The smoke will remarkably weaken the received light on photosensitive element and then the detector will send out alarm due to the current variation.烟雾会显着削弱光敏元件上接收到的光,然后检测器会由于电流变化而发出警报。
