The Whelen Company is divided into four divisions and has a subsidiary called
Whelen Motorsports. The four divisions of the company are as follows: • The
Automotive Division — provides lightbars, dashlights, strobe kits, siren boxes, and other public warning systems to be mounted on or within vehicles, rotating sirens, and student alert systems with voice broadcast capability. • The
Industrial Division — provides public alert hardware for clientele in an industrial plant forum. • The
Aviation Division — provides warning equipment specifically for use on aircraft or airport directional lighting. • The
Mass Notification Products Division — provides hardware for mass notification, such as omnidirectional sirens (
electronic civil defense sirens), rotating sirens, and student alert systems with voice broadcast capability. An example product from the Mass Notification Products Division is the Whelen Hornet, which is an electronic
civil defense siren introduced in 1995. It contains a single 400-watt
speaker. The siren's appearance is best described as a small dish on a square rotator platform, with the single driver located at the center of the horn. It is the smallest outdoor siren made by Whelen. The siren can sound six signals, just like most other sirens produced by Whelen; however, it is not voice-capable like the company's WPS-2900 and WPS-4000 series sirens. Whelen also produced the WPS-3000. The
