INM 725B Rev 21455 SIGNAL VOLTAGE SETTING / WIRING5 1 Setting Inputs for use with 24VDC or 125VDCOn standard RTK 725B systems each 4 channel alarm card is suitable for use with 24VDC or125VDC signal inputs.Each channel on the alarm card is equipped with a 3 pin header and 2 way shorting bar thatallows the user to set the input to match the required signal input voltage level. (24V or 125V)5 2 Setting Inputs for use with 24VAC or 125VACRTK 725B signal inputs are bi-polar and therefore suitable for use with 24VAC or 125VAC.Each channel on the alarm card is equipped with a 3 pin header and 2 way shorting bar thatallows the user to set the input to match the required signal input voltage level. (24V or 125V)WARNING !Remove ALL power from the unit and fully remove the card before changingany jumpersHowever when using AC inputs additional filters are added which result in a 25mS response timebefore the alarm activates.In systems using Time Stamping the alarm would still indicate the time the alarm first occurredto the millisecond.To set the signal supply voltage on each input to either 24VDC, 24VAC, 125VDC or 125VAC adrop-down menu is provided in the Configuration Software. Selection is made under the Input tabusing the drop-down menu labelled “Field Contact Voltage (V)”LK1LK2LK3LK4125V 24V24V125V125V 24VORLK1LK1SIGNAL SUPPLYVOLTAGE SETTINGCHANNEL 1CHANNEL 1CHANNEL 2CHANNEL 4CHANNEL 3SIGNAL SUPPLYSET TO 24VSIGNAL SUPPLYSET TO 125V
