The Vortex-R Series is a line of electronic sirens produced by Whelen Engineering. It consists of four models, the VORTEXR1, VORTEX2, VORTEX3 and VORTEX4. All of which look identical from the outside. They can be identified by the square box protruding out from the rotator box. Older models also have large fins on the back. Unlike the 4000 Series they do not do voice.
