NSI-TA725 Light Duty and General Purpose Buzzer with Switch, 8-16 VAC, 3-6 VDC, 1 Amp Current, 2-1/2" Width, 3" Height, 1" Depth, Ohm

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.

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.

Does what it is supposed to do, but it sounds awful mounted on a large sounding board.

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.

small but powerful

took a few tries from maintenance and we finally had to give up. I should return it -- it's still a ding dong not a loud buzzer which I needed

The media could not be loaded. 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.

The NSI-TA725 was dead on arrival. It would vibrate, but did not make any audible sound. The Thomas & Betts DH920 Series AP worked perfectly after installation!
