This is a map of their system. They had a system of Whelen WPS-4004s prior to the installation of the ATI system in 2006-07. The ATIs replaced them directly with one being mounted on the same pole or indirectly. Prior to 2012 the system consisted of rotating HPSS32Rs, but after issues arose the year following the installation of the sirens that progressively got worse and worse the replaced the heads with the more common omni version of the HPSS32. They still have issues with the system which eventually led to them testing weekly when the system had glitches during a warning back in 2015.
