Only markings I can find that aren’t referring to pads on the board is “TECHNO, INC. PCMAC100”

TLDR I got lucky and this alarm sounded in school and I almost got my phone taken away

For context, I’m Mexican, and of course I’m studying in Mexico. I study in a private, non-religious school, in which it’s very much banned to even bring a phone to the school. I’m in the equivalent of eight grade. Two days ago, I was in physics class, after I finished my work, i decided to watch Instagram Reels, because of course I was. The class had just ended, at 12 A.M., the first exact time the alarm sounded. I panicked, shut off my phone while the whole class laughed, knowing it was my phone. After physics, which was a blessing because that teacher doesn’t GAF about phones in class, so he didn’t inform the principal. After that period, I had technology, so we went to the computer lab, in which I sat next to one of my friends. He just so happened to have to go to the bathroom, where he passed by a friend on another group, where he told my friend that they were going through backpacks to take away phones from students all the way from 7th to 9th grade (the equivalent to middle school here in Mexico), long story short tech period passed and I went to last period, history, in which I was extra nervous, due to the fact that my history teacher is my home room (I think? Idk the equivalence) teacher, which could get me in trouble with the principal. Keep in mind, the likelihood of the principal or guidance counselor going through backpacks is still high at that point. I was so worried that I decided to just go to the restroom and try to calm myself down. My campus (if I can call it that, tbh idk) is divided between two institutions, one of them is middle school (7-9th) and the other is high school (10-12th). When I went to the bathroom, I saw high schoolers out in the hall. I realized they could no longer go through backpacks. I saw my classmates and they decided not to tell my history teacher. In second period, I tried to disable it, I disabled every government alert I could. But guess what? Here in Mexico, they didnt implement it correctly, and they set it as a presidential alert, one of the types of alert you can’t disable.
