Uhppote Sound-light Fire alarm sound won't stop after it turned off

I’ve already figured out the issue. Look at this video to see how I solved the issue. I try to install Uhppote Sound-light Fire alarm, but the sound won't stop after it turned off. How do I solve this issue? Any help would be appreciated thank you.

You’re supposed to add a 9 V

The problem is you have to wire it directly to the switch.

I'm having the same issue how do I wire directly to the switch

[@VOLTRONDEFENDER4440]

I had wired it and it works but YOU SHOULDNT WIRE THE FIRE ALARM DIRECTLY TO THE POWER SUPPLY THATS WHAT CAUSED IT! one wire goes to the board another goes to the fire alarm then one wire from the board goes from that to the fire alarm!

The problem is he has not wired it directly to the switch.
