"Regulated 24 VDC"refers to the voltage range of 16 to 33 VDC per UL Standard 1971, Signaling Devices for the Hearing <br /> Impaired,changes effective May 1,2004 This voltage range is the absolute operating range. Operation outside of this range <br /> may cause permanent damage to the appliance. Please note that 16 VDC is the lowest operating voltage that is allowed at the <br /> last appliance on the NAC under worst case conditions. <br /> 3. The maximum RMS strobe current listed is the device nameplate rating.Strobe designs are constant wattage and the <br /> maximum 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 /> 3 S4906-0003-5 9/2009 <br />
