A button behind a pane of glass. Pressing the button opens a hatch in the ceiling from which water runs, the Redstone torch flashes and you hear an alarm sound.
Instructions:

Try to recreate the redstone circuit from the picture.
On the top left of the screen is a memory cell to store whether the alarm is currently active or not. At the top right is a pulse generator which triggers the alarm redstone flare and the note block.
To reset the alarm, simply reset the memory cell, e.g. by means of a button, and replace the glass pane.
both ideas work. very good in warehouses or schools
How did you make the piston retract after you push the button?
To reset this you have to press a button, which is attached to the single block on the left in the second screenshot. This resets the memory cell.
I see. The top left is this "memory cell
I'm putting this in my house.
Super cool ! Make more so redstone
the redstone torch can not flash at all because it is washed away by the water^^
You shouldn't put them on the floor either
...I've been hit in the face again!
I built it without the water.
How do you get the disk in front of the button?
Just build in front of it :P. The button is one block further back than the disc.
oh soo thank you
Is great must say in my current project I have also installed such a fire alarm system. Only I did it a little differently with a command block system. So it is more economical space and thus you can install almost anywhere a system. But thanks xxluke for the idea.
@ChaosCole how did you build this? Can you send me a screenshot?
this is very cool please more of this xxluke
IS NOT ABOUT GOING DOWN
@just399 what's your problem?
Yeah, what's wrong? If you can't provide a critique, but instead grumble so outrageously, then at least justify the whole thing.
wussste not that you can build a fire alarm so realistic xD
That might be a cool idea too.
Good idea, but the fire alarm can also be automated with command blocks.
That's a great idea. Could have used it when I was experimenting with a fireplace in the log cabin yesterday. It caught fire three times until I started experimenting on wood to fire spacing first. If there's nothing on this yet, I might post it here again because it's a common question on the net.
@Thragor: There are already a few fireplaces here, so please don't upload any more.

Well Gera de space-saving is not. The once to build goes yes Still but just in a yoke house on each floor. That needs space... But good idea, in practice difficult to not satisfactorily implementable.
Neutral
Super
The one in front of the button, is that a block of glass or a sheet of glass???
@cola: With me, it's a glass block, because there were no discs back then. But of course you can also just take a pane.
ok
I can't get a button on the talkstine block.
This is red wool, not redstone block.
Cool
