Speakers are for connection to conventional fire alarm audio circuits.Anechoic speaker output ratings are typically more representative <br /> of actual installed sound output. <br /> 2. "Regulated 24 VDC"refers to the voltage range of 16 to 33 VDC per UL Standard 1971,Signaling Devices for the Hearing Impaired, <br /> changes effective May 1,2004.This voltage range is the absolute operating range.Operation outside of this range may cause <br /> permanent damage to the appliance.Please note that 16 VDC is the lowest operating voltage that is allowed at the last appliance on <br /> 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 maximum RMS <br /> current rating occurs at the lowest allowable operating voltage.(RMS is root mean square and refers to the effective value of a varying <br /> current waveform.) <br /> 85 <br /> E <br /> 83 <br /> O <br /> 82 <br /> 81 <br /> m 80 <br /> J <br /> ` 79 <br /> 7 <br /> y 78 <br /> mti <br /> IL 77 <br /> C <br /> e <br /> G 76 <br /> w <br /> 75 <br /> 90 80 70 60 50 40 30 20 10 0 10 20 30 40 50 60 70 80 90 <br /> Angular Displacement(Degrees)on Horizontal Axis <br /> -2kHz-4M <br /> 3 S4906-0003-4 512008 <br />
