NSI TA725 Light Duty Buzzer with Switch, 8-16VAC/3-6VDC, 1 A, 2" Width | 8-16 VAC; 3-6 VDC; 1 Amp Current; 2-1/2" Width; 3" Height; 1" Depth

Worked good for the application

This Saved me a lot of problems.The door buzzer at my Wife's store had died and it is an old buzzer system.I was dreading having to replace it when I found this which is exactly like the original.I hooked it up and it works perfectly. A bit loud for my taste but it does get the staffs attention.

This is definately great for a loud environment to hear. Better than the $9 item at your local big box stores. Appeared commercial grade.

I have tried it on both AC and DC voltage. This is 6vdc in this video. It’s loud but not too loud. It will definitely get your attention.

I really liked the idea of having a buzzer ringing vs. a bell style. This did not work for our usage and wished it did.

Works great discrete profile and just loud enough

We have mice that moved into one of our outside walls. My HOA takes a little while to get the exterminator going and I decided to take matters into my own hands by giving the mice a headache. I attached this buzzer to a block of wood, which then I carefully have attached at intervals to different areas on my cove base. Running on 5 volts from a repurposed power adapter, it produces a satisfying loud hum, and makes the wall vibrate. At first the critters moved, so I followed them. It sounds like they're gone now.

They work great. Incredibly loud, though. Louder and more startling than I thought it would be. I tried to attach a piece of acoustical felt to it, so it would absorb sound. It didn’t work. But the unit itself works great!

Good product

Worked as expected

As expected

Le signal sonore n'est pas très fort et quand il sonne on croirait qu'il est defectueux.

Ring ding a ling, great!
