Ionization Smoke Detector- for 12VDC Security System

Description

Ionization smoke detector responds to smoke. It has an ionization chamber inside. The ionization chamber with ions in it will generate a constant, small electric current.When smoke enters this detector, the smoke particles attach to the ions inside the chamber and neutralize them. That will cause the current inside the chamber drop, therefore trigger the detector alarm.
