General
The HPSS-16R was a variant of the HPSS16, but it’s a rotating version. This siren is closely related to the Whelen WPS-4000 Series in how it functions, as well as it's physical appearance. Both using a throat to project sound, a very similar rotator; lacking collector rings and utilizing belts to drive the system. This siren operates with 2 speakers (drivers). These sirens are very uncommon, as they are said to have just released, and not known to be the most reliable. For a while, the HPSS-16R was also offered in a 3200 watt, HPSS-32 rotating variant, known as the HPSS-32R. The HPSS-32R was similar to the HPSS-16R, except it had four throats instead of two and double the wattage. The HPSS-32R is only known to be in at least one system. In 2018, ATI quietly discontinued the HPSS-16R and has removed the siren from their product line and website.
