    How long can this product can be used?

    Under normal circumstances, this product can be used for 10 years.


    What is the alarm volume of this product?

    ≥85 dB(A) at 3 meters.


    Why does the alarm do not respond when I simulate smoke to test?

    It may be that the concentration of smoke has not yet reached the alarm threshold. Simulating smoke yourself can easily cause a fire. For your safety, we recommend that you use our Test function to test the equipment.

    How to test whether the alarm function is normal?

    Install the bracket on the product (a short chirp will be heard when the installation is successful), press and hold the Test button, and then you will hear a chirp sound, which means that the alarm is working normally. If it does not sound, it may be an internal failure of the alarm, you can contact https://www.meross.com/support/Email_Support. You don't need to simulate the smoke test equipment yourself.

    I have bought multiple devices. When a fire triggers an alarm, will other alarms follow along with it?

    Sorry, this alarm does NOT support this function. But we have a smart smoke alarm that supports this function, the model is GS559A, you can search it.
