Whelen HornetEdit

The Whelen Hornet is an electronic civil defense siren. It was 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;[10] however, it is not voice-capable like the WPS-2900 and WPS-4000 series sirens. Whelen also produced the WPS-3000.
