Functions
1. Detection. Press detection button, it can fully check the alarm functions. And the alarm light flashes quickly with a rapid sound. 2. Alarm. In the normal environment, The alarm will flash automatically every 10S and automatically detects the concentration of smoke in the surrounding environment at regular intervals(around 1.6s),If the smoke concentration is close to the alarm value, the alarm starts to perform intelligent calculation, and the alarm indicator light starts to flash. If the calculation result reaches or exceeds the alarm value, the alarm will start the sound-light alarm and start the relay. When the ambient smoke concentration drops below the alarm value, the alarm will automatically return to the normal working state. 3. Output. Passive contact output. NC or NO two kinds of output.
