The WPS-2800 series was a line of electronic, omnidirectional sirens produced by Whelen Engineering. They were an update to the WPS-2700 series, supporting more cells in a stack.

They can be identified from the WPS-2700 series and WPS-2900 series by their large, visible screens close to the outer edges of the cells.

Controllers

The very first WPS-2800s used the same analog ESC-864 controllers utilized by their predecessors. These were soon replaced by digital ESC-864s running at a 465 hz base frequency. Towards the latter half of the series' production, the 864 was succeeded by the ESC-2020, which used 435 hz as a base frequency. These controllers soon became infamous for reliability issues and clipping tones, and soon before the 2800 series was replaced, a new revision of the 2020 appeared, using a 560 hz base frequency. Not many of these were installed with 2800s, as they were soon replaced by the WPS-2900 line.
