Wow - they weren't kidding about deafening!

Reviewer: from MARSHALL, MN US

I swapped out the buzzer on my water alarm kit (All Electronics P/N MK-108) with this piezo siren. The result is a siren that can be heard very clearly two floors up. This unit has the ability to put out a louder, more irritating, sound than units twice it's size. The very low power consumption is the icing on the cake.

Perfect Recovery siren

Reviewer: from Asheville, NC

Our team used this for the recovery siren in our near-space balloon payload. (Along with a GPS Radio Tracker) We probably would never have found it up in a tree without it. Survived two flights so far, each more than 20 miles up in the atmosphere!

Use a decoupling cap if you use a resistor

Reviewer: from US

To the last poster: you cannot put a resistor in series to drop the voltage. Piezos have capacitance which is charged - which results in motion of the ceramic material - which is what you hear. Also, the chip which drives the piezo has a minimum operating voltage to function - which is not met with a resistor in series - due to huge voltage drops as the piezo charges.

To lower the volume, use a REGULATED supply of lower voltage, or if you use a series resistor - a cap across the module - consisting of at least 100 uF - paralleled by a 1 uF ceramic.

These approaches will allow you to get quite a dynamic range.

LOUD!!!

Reviewer: from Lititz PA

Almost too loud @ 12VDC. I bought this to wake me up for ambulance call in the middle of the night & thinking about getting something not as loud. This would be perfect if you a distance from the siren or in a noisy enviornment. You won't be disappointed with this siren!!

I've seen these before

Reviewer: from Denver, CO

These are commonly used on those emergency "If opened alarm will sound" doors. Very loud and annoying. I can't even imagine the sound it would make inside a car at 12v.
