This smoke alarm is equipped with a self-test mechanism. At least once a month at a random moment, the device automatically checks the functionality of the sensor and the siren. During a successful test, the detector will beep and blink briefly. If problems are detected, the detector switches to error mode. Replace the device immediately if the error message occurs!
