Hello MR !

I have a hard-wired smoke detector upstair near the bedrooms, and it buzzed randomly for like 5 seconds last night at 4AM.
Very rough to wake up to that, obv. no smoke or anything.
So I tought the battery backup inside was dying, to my surprise, I cannot open the cover so there is no batteries inside.

So why the fck did it buzzed randomly ? Voltage spike ?

I took no chance and bought a new battery one and put it beside to be sure, still, i'd like to understand.
 
J'ai eu le meme probleme avec un des miens.

Il buzzait random et un soir je me suis décidé a l'ouvrir. Il avait fondu.....

C'était un Kidde, j'ai envoyé une photo de l'intérieur fondu a la compagnie, ils m'en ont envoyé un neuf avec une boite de retour pour le defect.
