Smoke Sensors Dealers in Meerut

We bring forth high performance Ionization Smoke Detectors. This Ionisation Smoke Detector is available under the name of Context Plus XP95 onization smoke detector. This Ionisation Smoke Detector comes with a molded self-extinguishing white polycarbonate case having wind resistant smoke inlets. There are stainless Steel wiper contacts that connect the Ionisation Smoke Detector to the terminals in the mounting base. Inside the Ionisation Smoke Detector case there is a printed circuit board that has the ionization chamber mounted on a side and the signal processing, address capture and communications electronics on the other. The ionization chamber system is an inner reference chamber which lies inside an outer smoke chamber. The outer smoke chamber is equipped with smoke inlet apertures fitted with an insect resistant mesh. There is radioactive source holder and the outer smoke chamber that are the positive and negative electrodes respectively. An americium 241 radioactive source mounted within the inner reference chamber irradiates the air in both chambers to produce positive and negative ions. On applying a voltage across these electrodes an electric field is formed. The ions are attracted to the electrode of the opposite sign, some ions collide and recombine, but the final result is that a small electric current flows between the two electrodes. Download
