Review on DiversiTech UA 1 Universal Alarm 24V by Knate Scarpelli

I bought this as a horn for my aquarium (the apex controller will turn it on if it detects a problem). It beeps intermittently when it turns on, and the mute button is great for turning it off when troubleshooting. My only complaint about it is that it's too quiet. I had to install it outside of the aquarium cabinet to make it loud enough and distracting enough. Probably around 75 dB. It would be ideal if it were a little louder and/or had an adjustable volume control.
