"Regulated 24 VDC" refers to the voltage range of 16 to 33 VDC per UL Standard 1971, Signaling Devices for the <br />Hearing Impaired, changes effective May 1, 2004. This voltage range is the absolute operating range. Operation outside <br />of this range may cause permanent damage to the appliance. Please note that 16 VDC is the lowest operating voltage <br />that is allowed at the last appliance on the NAC under worst case conditions. <br />2. The maximum RMS current listed is the device nameplate rating. Strobe designs are constant wattage and the maximum <br />RMS current rating occurs at the lowest allowable operating voltage. (RMS is root mean square and refers to the <br />effective value of a varying current waveform.) <br />Installation Reference, Adapter Plate, Guard, and Adapter Skirt <br />45 Box <br />E <br />0 <br />Oj <br />O _ — O <br />Uo IF ONE A r <br />4905-9931 Adapter Plate <br />O 4905-9961 Optional Wire Guard <br />(shown here for reference only, <br />4905-9931 Adapter Plate can be used on other mounting options) <br />Surface Mounting Reference <br />with Optional Adapter Skirt <br />and Optional Wire Guard <br />Surface mount conduit and <br />box shown for reference <br />4" (102 mm) square <br />box profile, 1-1/2. ---- <br />(38 mm) deep l <br />Optional,— L : <br />4905-9961 <br />Wire Guard <br />Strobe '---- <br />Optional Surface Mount Adapter Skirt, <br />1-1/2" deep: 4905-9937, Red; <br />4905-9940, White (conduit knockouts <br />are provided on all four sides) <br />3 S4904-0005-5 9/2004 <br />
