Details of the product function:
Standby mode:after the product is installed, if the smoke alarm device is operating properly, the red LED-Flashing once every 40 seconds;
Alarm mode: when the smoke alarm device detect particles of combustion and the concentration of smoke reaches the alarm threshold, the red LED will flash once per second with pulsating alarm until the air is cleared.
