Wolo Alert 4000 Electronic Siren and P.A. Systems

Wolo Alert 4000 P.A. combo systems feature a powerful electronic siren with three different sound alerts--a wail, a yelp, and an air horn. The sirens are built with state-of-the-art electronics to provide years of dependable service. You can easily mount the compact controller on a dashboard with little space available. The three emergency sounds and public address system have a full range of adjustable sound output, controlled by a simple turn of the rotary volume control; select air horn or siren sounds with the push of a button. Model 4000 systems are great for volunteer fire personnel in states that permit the use of sirens. The 12 V units come complete with a 100 RMS speaker, a plug-in microphone, a metal mounting bracket, and mounting hardware. Choose from among the standard 50 watt systems, or a Wolo Alert with more wattage for a cleaner, richer sound. Show Less
