JC-WS-ZN01 Smoke Detector

Self-check: Press the check button, the LED of the detector is always on, and an alarm sound is emitted at the same time (Note: The self-check only detects the internal functions of the detector itself, and there is no relay signal output during the self-check). Work: Normally, the indicator light of the detector will flash about every 6 seconds. The detector automatically detects the concentration of smoke in the surrounding environment, and automatically compensates for sensitivity according to the environment in which it is used. When the smoke density is close to the alarm value, the detector speeds up the intelligent calculation of the smoke density trend, and the alarm indicator starts to flash. If the calculation result reaches or exceeds the alarm value, the detector will start audible and visual alarm and start the relay output. When the smoke concentration in the surrounding environment drops below the alarm value, the detector automatically resumes its normal working state.
