HC-202D Ionization Smoke Detector

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. Features : * With dual LED, easy to observe state of detector. * With dual LED flash once every 4 ~ 6 seconds in peacetime to show if the detector work normally. * The dual LED light up constantly when the detector alarms. * With ( -R) contact to connect to a remote indicating lamp to show alarm signal in different area.
