求助: smoke detector alarm sounded without any obvious reason

The whole house smoke detector alarm sounded loudly once last night, wake up everybody in the family, then, the sound stopped and nothing happened since then.

If it's lack of battery issue, then, it should have sharp reminder sound, also, it should continue every other several minitues. So, I suspect it's smoke detector system mulfunction.

What should I do next?

Appreciate your help!!!
