Selectable Output Wall Speaker/Strobes SP2 and SP3 Series Speaker/Strobes offer enhanced features that include the widest range of candela options available, the capability to self-adjust for 12 or 24 volt operation, and the fidelity sound quality expected from SpectrAlert speaker technology. Performance. SpectrAlert® Selectable Output Speaker/Strobes offer average current draws that are not only lower than conventional fixed-candela SpectrAlert products, but also lower than similar selectable candela products. In addition, the broad frequency response range and low harmonic distortion provided by SpectrAlert speaker technology provides an accurate and intelligible broadcast of evacuation messages. Installation. SpectrAlert Selectable Output Speaker/Strobes offer a variety of installation-friendly features, such as the ability to mount to a 4˝ × 4˝ × 21⁄8˝ back box without the need for an extension ring. Also, with the field-reversible strobe, the speaker/strobe may be either left- or right-mounted to avoid potential obstructions. Flexibility. SpectrAlert Selectable Output Speaker/Strobes offer the broadest range of candela options. In addition, the 15 cd and 15/75 cd options can operate on either 12V or 24V, with no setting required; the device recognizes the applied voltage and self-adjusts to the correct setting automatically. The speaker voltage, either 25.0 or 70.7, and power tap settings, ¼, ½, 1, or 2 watt, are field-selectable. Features • Fidelity sound quality (SP2) • Enhanced SPL (SP3) • Operates on either 12V or 24V • Widest range of candela options: 12V: 15 and 15/75 candela options 24V: 15, 15/75, 30, 75, and 110 candela options • Easy candela selection • 25.0 and 70.7 volt speaker with four field-selectable power taps • Field-reversible strobe for left- or right-mounting • Synchronizable with MDL Sync•Circuit™ Module • Optional surface-mount back box skirt available Aesthetics. SpectrAlert Selectable Output Speaker/Strobes incorporate the same stylish, low profile design as the conventional SpectrAlert products, for a consistent and aesthetically pleasing appearance across the entire product line.

INSERT SCREWDRIVER TO REMOVE Explanation of Published Strobe Specifications In May 2004, Underwriters Laboratories changed standard UL 1971 to require that operating current measurements are made using RMS (root mean square) instead of peak or average values. RMS measurements more accurately predict the power consumption of a device since they take into account the entire current draw profile including surge, repetitive surge, and peak values. The published RMS current is the maximum operating current of that device within its operating voltage range. This current maximum may or may not occur at the endpoints of the voltage range. In May 2004, UL also changed the way they list the voltage range of a device. All 12V products will be listed between 8–17.5V and all 24V products will be listed between 16–33V. These devices are considered “regulated.” Any product that does not operate within these ranges will be listed as a “special application” with its operating voltage specified on the device.
