CF-03-022- Photoelectric Smoke Detector A light source and a photosensitive sensor are arranged so that the rays from the light source do not normally fall onto the photosensitive sensor When smoke particles enter the light path, some of the light is scattered by...
CF-03-021- Photoelectric Smoke Detector A smoke detector using the principle of optical detection of visible particles of combustion. Two Types of Detectors Chamber or Light Scattering Projected Beam or Light...
CF-03-19- Ionization Smoke Detector A small amount of radioactive material is used to ionize the air between two differentially charged electrodes to sense the presence of smoke particles Smoke particles entering the ionization volume decrease the conductance of the...
