fire alarms different smoke detector types 2/3/4 wired smoke detectors for you
Product introduction
This product is a photoelectric smoke detectorwith options of 2-wire model and 4-wire model. The smoke chamber using the principle of smoke particles reflecting infrared lights can accurately detect early smoke of a fire. The smoke detector will go intoalarmwhen signal level exceeds the alarm threshold and send the alarm signal to the control panel. During an alarm,the LED will constantly bright.
