Custer Electric, Inc. is an Indiana-based electrical contractor that specializes in outdoor lighting systems and outdoor warning siren systems. While mainly a siren maintenance contractor, they also have produced a few small electronic sirens that are made to be as inexpensive as possible. None of these small sirens exist outside of east-central Indiana. The largest and most well-known system of these sirens is in Rushville, Indiana, which has around 5 of these sirens.

All of the installations have controllers consisting of an older, analog fire truck siren and a radio, with a set of speakers and a battery on top of the pole. The model of speakers used varies greatly between installations. The most common of these speaker types is the Electro-Voice/University Sound Cobreflex model, which is used on the installations in Rushville and Knightstown.

Many younger/inexperienced enthusiasts will find one of these speakers on an unrelated PA speaker installation and believe that it is a Custer Electric siren, when it is little more than a basic PA speaker. It is very unlikely that Custer would install any sirens very far from where they are headquartered.
