L1-02B-13- Ionization Smoke Detector

L1-02B-13- Ionization Smoke Detector  Normal Situation A typical ionization chamber consists of two electrically charged plates and a radioactive source (typically Americium 241) for ionizing the air between the plates. The radioactive source emits particles that...

L1-02B-12- Ionization Smoke Detector

L1-02B-12- Ionization Smoke Detector Air in chamber is “ionized” to allow the air to conduct current. Smoke particles reduce the level of ionization, disrupting the electric current flow and producing an...

L1-02B-09- Photoelectric Beam Type Smoke Detector

L1-02B-09- Photoelectric Beam Type Smoke Detector The light obscuration detector employs a light source and a photosensitive receiving device, such as a photodiode. When smoke particles partially block the light beam, the reduction in light reaching the photosensitive...
