NOTIFICATION
SPH-15 Series Supervised Horn Loudspeaker
Models Available SPH-15R
Product Overview 25.0 and 70.7 Vrms dual voltage settings Seven field-selectable watt/impedance selections Double re-entrant design Vertical and horizontal positioning Suitable for life safety and communications Available with red finish System Sensor's SPH-15 series speakers combine performance, functionality, and flexibility. Performance. Utilizing a high-efficiency compression driver, the SPH-15 loudspeaker is capable of projecting through high ambient sound levels typically found in warehouses, factory settings, and mechanical equipment rooms. The horn loudspeaker is equipped with a 7-position watt/impedance switch, providing for tap selection up to 15 watts RMS power handling capability. Functionality. The SPH-15 is listed to UL 1480, and is designed to provide accurate reproduction of audible emergency and protective signals/messages. The SPH-15 is weather-resistant to provide protection against water, humidity, and corrosion. Flexibility. The SPH-15 is equipped with a dual voltage transformer capable of operating on either 25.0 or 70.7 volts. A mounting bracket permits surfacemounting in either a horizontal or vertical position, allowing for directional sound dispersion, which maximizes sound projection and penetration.
