Technology. Like the original SpectrAlert, the SpectrAlert ceiling mount series offer significant current draw reductions over other ceiling mount strobes and horn/strobes. Installation. SpectrAlert’s compact design also offers installation savings. The strobe and horn/strobe models mount to a 4˝×4˝×11⁄2˝ back box, and take up little room in the back box, making connections easier. And with SpectrAlert’s round shape, it is not necessary to align the back box with the room’s walls. SpectrAlert always lines up. Flexibility. SpectrAlert ceiling mount strobes and horn/strobes are available in seven different candelas, including 177 candela for sleeping areas. The horn/ strobe’s tones are field-selectable through the use of a three position switch located on the back of the unit. Selections include electromechanical and 3 KHz tones, temporal and non-temporal patterns, and high and low volume. Aesthetics. SpectrAlert ceiling strobes and horn/strobes offer a design that is sensi- tive to the aesthetic demands of ceiling mount applications. The round shape maintains a low profile appearance, similar to that of a smoke detector and provides clearly visible “FIRE” identification from all angles.

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. During 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. Those 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. Notes 1. Current draw for strobe-only products is shown in Table 1-A. Similarly, UL tests the audibility of devices in accordance 2. 24VDC 2-wire horn/strobe current draw is shown in Table 1-C. with UL 464 by measuring them across the operating voltage range to determine the minimum sound pressure level 3. Current draw for other horn/strobe power supplies can be calculated by adding the strobe current in Table 1-A to the produced at any particular setting. horn current in Table 1-B from the chosen settings.
