Large Piezo Alarm - 16 Tone Product Help and Resources
Core Skill: Soldering
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Rookie - The number of pins increases, and you will have to determine polarity of components and some of the components might be a bit trickier or close together. You might need solder wick or flux.

Core Skill: Electrical Prototyping
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Loud & Easy to use.
This Alarm arrived fast and was very easy to use I was amazed at the volume, I would buy this again in a heartbeat.
Large piezo 16 sounds alarm buzzer
Very loud (can be dimmed), 16 very different tones! I am very happy with it.
Pretty neat device
It is so adjustable to so many different tones and sounds. It's also pretty loud for such a small device.
Simple loud siren
I needed a siren to beep whenever a door is opened. This is a little loud for that, but it could be covered to dampen the noise if needed. One interesting thing I found is I was able to run it on 3.3v and only draw 2ma. This allowed me to power it directly off an IO pin from an esp8266 module.
How hard do you think it would be to crack into that dip switch so that an Arduino Uno could control the tones ?
I am not sure but I think it would be easier to use a normal piezo buzzer and control the tones directly from the Arduino. You could use the tone(pin, frequency, duration) function to do so.
