The WPS-4000 Series is a line of electronic sirens produced by Whelen Engineering. It consists of three models, the WPS4003, WPS4004 and WPS4008. The WPS4003 and WPS4004 are still in production, the WPS4008 is not. The WPS4003 and WPS4004 look similar from the outside. The difference between the two models is that the WPS4003 has three speaker drivers while the WPS4004 has four, which the last number of the models stands for.
