Batboard

I will be using a maxtrac and the horn lights feature for a station alert reciever. I need some help with the alarm ideas. I found burgaler type alarms but at 110db they are much too loud and are difficult to "muffle". Anyone have a better and inexpensive idea of some type of 12 volt alarm that is not too loud?

Here is one i have used before, it can be muffled fairly easy while still getting plenty of noise to wake the dead if needed.

It's inexpensive and worth a shot to tinker with and see if it suits your needs. They have other piezo buzzers as well if you want to try others.
