All 12V products will be listed <br /> are made using RMS (root mean square) instead of peak between 8 - 17SV and all 24V products will be listed <br /> or average values. RMS measurements inore accurately between 16 - 33V Tliose devices are considered "regulat- <br /> predict tlle power consumption of a device since tlley take ed". Any product that does nat operate within these ranges <br /> into account the entire current draw profile including surge> will be ]isted as a "specia] application° witll its operating <br /> repetitive surge, arid peak values. The published RMS cur- voltage specified on the device. <br /> rent is the maximum operating current of that device within <br /> its operating voltage rarige. This current maximuin inay or Notes <br /> may not occur at the endpoints of the voltage range. <br /> 1. Current draw for strobe-only products is shown in Table 1-A. <br /> Similarly, UL tests the audibility of devices in accordance 2• 24VDC 2-wire horn/strobe current draw is shown in Table <br /> with UL 464 by measuring them across the operating volt- 1-C <br /> age range to determine the minimum sound pressure level 3. Current draw for other horn/strobe power supplies can be <br /> produced at any particular setting calculated by adding the strobe current in Tabie 1-A to the <br /> horn current in Table 1-B from the chosen settings. <br />
