1、 Smoke alarms can be divided into two types based on information transmission methods: wired and wireless, from the detector to the host. Most wired alarms are networked and require an external power supply, but can be linked with other systems, such as sprinkler and alarm systems. Once an accident occurs, they can be immediately linked and processed, and are mostly used in supermarkets, office buildings, and other places.

而無(wú)線的則為獨(dú)立式，主要使用電池，相比有線來(lái)說(shuō)，安裝更方便，不需要額外找電源插口，但需要定期 更換電池。目前一些智能煙霧報(bào)警器，增加了WIFI模塊，即使是獨(dú)立式也可以與同網(wǎng)絡(luò)環(huán)境下的其他報(bào)警產(chǎn) 品聯(lián)動(dòng)。從安裝角度來(lái)看，獨(dú)立型大多為直接粘貼式，通過(guò)膠直接粘貼在天花板上即可。

The wireless version is independent and mainly uses batteries. Compared to wired versions, it is more convenient to install and does not require additional power sockets, but requires regular battery replacement. At present, some intelligent smoke alarms have added WIFI modules, which can even be independent and linked with other alarm products in the same network environment. From an installation perspective, most independent models are directly attached, which can be directly attached to the ceiling through adhesive.

二、煙霧報(bào)警器從使用的傳感器可分為

2、 Smoke alarms can be divided into

離子煙霧報(bào)警器

Ionic smoke alarm

離子煙霧報(bào)警器有一個(gè)電離室，離子室所用放射元素一一鋸241 (Am241),強(qiáng)度約0.8微居里左右，正 常狀態(tài)下處于電場(chǎng)的平衡狀態(tài)，當(dāng)有煙塵進(jìn)入電離室會(huì)破壞這種平衡關(guān)系，報(bào)警電路檢測(cè)到濃度超過(guò)設(shè)定的閾 值發(fā)出報(bào)警。

The ion smoke alarm has an ionization chamber, where the radioactive elements used in the ionization chamber are sawn 241 (Am241), with an intensity of about 0.8 microcuries. Under normal conditions, it is in an equilibrium state of the electric field. When smoke enters the ionization chamber, it will disrupt this equilibrium relationship. The alarm circuit detects that the concentration exceeds the set threshold and sends an alarm.

它是在電離室內(nèi)含有少量放射性物質(zhì)，可使電離室內(nèi)空氣成為導(dǎo)體，允許定電流在兩個(gè)電極之間的空氣中 通過(guò)，射線使局部空氣成電離狀態(tài)，經(jīng)電壓作用形成離子流，這就給電離室一個(gè)有效的導(dǎo)電性。當(dāng)煙粒子 進(jìn)入電離化區(qū)域時(shí)，它們由于與離子相接合而降低了空氣的導(dǎo)電性，形成離子移動(dòng)的減弱。當(dāng)導(dǎo)電性低于預(yù)定 值時(shí)，探測(cè)器發(fā)出警報(bào)。

It contains a small amount of radioactive material in the ionization chamber, which can make the air inside the ionization chamber a conductor, allowing a constant current to pass through the air between two electrodes. The radiation ionizes the local air and forms an ion current through the action of voltage, providing an effective conductivity to the ionization chamber. When smoke particles enter the ionized region, they reduce the conductivity of the air due to their binding with ions, resulting in a weakening of ion movement. When the conductivity falls below the predetermined value, the detector emits an alarm.

光電煙霧報(bào)警器

Photoelectric smoke alarm

光電煙霧報(bào)警器內(nèi)有一個(gè)光學(xué)迷宮，安裝有紅外對(duì)管，無(wú)煙時(shí)紅外接收管收不到紅外發(fā)射管發(fā)出的紅外 光，當(dāng)煙塵進(jìn)入光學(xué)迷宮時(shí)，通過(guò)折射、反射，接收管接收到紅外光，智能報(bào)警電路判斷是否超過(guò)閾值，如果 超過(guò)發(fā)出警報(bào)

There is an optical maze inside the photoelectric smoke alarm, which is equipped with an infrared tube. When there is no smoke, the infrared receiving tube cannot receive the infrared light emitted by the infrared transmitting tube. When smoke enters the optical maze, the receiving tube receives infrared light through refraction and reflection. The intelligent alarm circuit determines whether the threshold is exceeded, and if it exceeds the threshold, an alarm will be issued

它是利用起火時(shí)產(chǎn)生的煙霧能夠改變光的傳播特性這一基本性質(zhì)而研制的。根據(jù)煙粒子對(duì)光線的吸收和散 射作用。光電感煙探測(cè)器又分為遮光型和散光型兩種。

It is developed based on the fundamental property that the smoke generated during a fire can change the propagation characteristics of light. Based on the absorption and scattering of light by smoke particles. Photoelectric smoke detectors are divided into two types: blackout type and astigmatic type.
