Alarm and acknowledge circuit ??

hello, can anyone help me to make alarm acknowledge circuit ? which can cancel the buzzer but if 2nd signal came it must active again ? please help me ..

Since you are posting in General Electronics, I am assuming you want a discrete solution. Google "RS flip flop transistor"

However, the Y part of your XY problem might be "how do I set and reset a latch in code?"

thank you for helping me,yes you are right. I need to make this without coding. I already tried RS FLIP FLOP CKT, but what can i do when I need to add more input, ??

I am not sure what you mean. Other alarm signals, with one acknowledge?

Can you give us a diagram?
