This is a tool I made a while back that will check model numbers of Simplex fire alarm horns, strobes, and horn/strobes in the 4901, 4903, and 4904 series. It will tell you what kind of signal it is and is useful for if you want to buy one on ebay, so you can make sure it is going to be usable or not.
