Next Generation High Powered Speaker Station

The Next Generation High Powered Speaker Station (HPSS) brings faster and more powerful processors, and additional interfaces, to the rugged outdoor electronic sirens that ATI Systems has been providing for large outdoor warning systems for over a quarter-century. This includes enhanced security and encryption, while minimizing the number of components, and increasing equipment longevity. The next generation product line combines ATI Systems’ field-proven features with several important enhancements delivering the most advanced solution on the market to date.

The High Powered Speaker Station (HPSS) provides exceptional voice clarity for outdoor mass notification applications where intelligibility of pre-recorded voice messages and live Public Address (PA) is critical. It is also capable of driving strobe lights and LED message signs for visual alerting in areas with high ambient noise levels. The HPSS is monitored, controlled, and activated by an ATI central control unit, REACT5000, or can operate as a standalone using the Local Operating Console (LOC) option.* It comes in two configurations, with either 1600 or 3200 watts of acoustic power. In the event of AC power loss, the batteries provide a full week of standby time followed by at least 30 minutes of continuous activation. In addition, ATI offers flexible on and off the grid power options. These units are recommended for use when intelligibility is the highest priority.
