Audible Alar,, iControls <br /> LC 1000 ; <br /> The LC 1000 series alarm consolesh <br /> are designed for use with any tanks ry <br /> mounted sensing device that trans- <br /> mits an alarm condition by opening or <br /> closing switch contacts.While the <br /> controls are usable with a variety of <br /> field sensors,the LC's are optimized <br /> for level control.They assure com- <br /> plete safety and minimum installation <br /> cost by requiring only low current, <br /> intrinsically safe wiring between con- <br /> sole and tank switch. <br /> Housed in a water tight enclosure, <br /> the solid state circuitry provides from <br /> one(1)to four(4)alarm channels for <br /> monitoring up to four independent ' '} , <br /> sensing points.Bright incandescentf <br /> alarm lights and a loud sounding horn t <br /> warn of alarm conditions.Dry con- <br /> tacts are provided for controlling your <br /> external devices such as pumps, <br /> valves,or remote alarm stations. <br /> Features <br /> Consoles can monitor multiple <br /> tanks - <br /> High and low level warning lights <br /> Audible alarm with reset button <br /> Multiple switches <br /> Push button test Meets Overfill Alarm Requirements <br /> Intrinsically safe operation of tank <br /> mounted sensors <br /> Operation <br /> e e e <br /> Each alarm channel transmits a 12 <br /> VDC signal to a tank mounted level <br /> switch.When the switch senses a <br /> level alarm condition,the switch <br /> transfers and the LC 1000 circuit <br /> energizes the audible horn and in- <br /> dicator light.The light will remain on <br /> after silencing the horn by pressing <br /> the reset button.At any time,an <br /> operator may test the alarm circuit by <br /> pressing the test button. <br /> APP <br /> F� File No.1Q3A4.AX — <br /> APPROM <br /> �EUECATOR <br /> T ical Application <br /> Li uid Level Control systems yp pp <br />
