## Overview

The Projects Unlimited 12VDC Programmable Buzzer is a cutting-edge audio device that allows users to program up to 30 seconds of sound from WAV or MP3 files. It connects easily to any 12VDC source and is compatible with USB 3.0, making it a versatile choice for various applications.

## Description

This device connects to any 12VDC source in the same manner as commonly available buzzers and piezo sounders, yet allows you to program up to 30 seconds of any WAV or MP3 file via USB from your computer. With the flexibility of programming your own sounds, you are no longer required to listen to the standard tones, beeps, buzzes or alarm signals. The programmable indicator allows you to give voice instructions along with a warning signal or a unique tone if multiple warning devices are used in the same area. Wide frequency capability allows this indicator to play a variety of tones, alarm signals, or voice and music messages. Once programmed, the indicator will play the file repetitively until power is turned off. The file is stored on internal non-volatile flash memory that can be reprogrammed as often as you like and will not erase until another file is programmed over it. While rated for 12VDC, the actual operating range is 7~24VDC, enabling compatibility with a variety of power sources, including AC adapters, automobile systems, security system power supplies, or a simple 9V battery. Features: Ability to program any WAV or MP3 file Volume can be controlled by file programming Flash memory can be programmed more than once Pre-programming available on certain quantities Repeating continuous operation Simple-to-use Windows interface Wide frequency range DC operating voltage Flange mounting Specifications: Rated Voltage: 12VDC Voltage Range: 7 ~ 24VDC Frequency Range: 100Hz ~ 6KHz Minimum SPL (10cm w/default 1KHz tone): 100dBA Max Rated Current: 350mA Max File Length: 33 seconds Sampling Rate: 12KHz

## Questions & Answers

**Q: windows 10 wont recognize? is there a driver i can update? or do I just have to return it?**
A: It is not windows 10 that is the problem.  It is not compatible with usb 3.0.  USB should be backwards compatible but this device will not be recognized.

**Q: Does it need power to program? Also the software link doesn’t work!!**
A: Program it with just USB connected, wires can be connected but power off.  Go to puiaudio.com, resources, programmable indicator software for download. Also, be aware you need an older USB card on your computer, USB2.0 is too fast. I used my computer to set up the file then had to dig my old laptop out of the closet and email myself the file to get it to load onto the indicator

**Q: What is the maximum frequency this can output?**
A: Frequency Range: 100Hz ~ 6KHz

**Q: Is this compatible with an Apple / Mac computer?**
A: No, Just PC Microsoft
