A noisemaker.

The noisemaker was a home-made device which continuously emitted a pitched noise when triggered, attracting a lot of attention. It could either be thrown, causing it to immediately being to beep for a few seconds before playing the noise, or placed, which would also result in it immediately beeping than playing the noise.

The upgraded version of the noisemaker had a longer duration and attracted attention over a wider area.

In 2137, residents aboard Sevastopol Station created blueprints to craft noisemakers.
