CLIMAX MOLYBDENUM COMPANY <br />SUBJECT: UTE PARK RADIO ALARM MONITOR <br />TO: ALL CONCERNED <br />FROM: GRANT BURGER <br />A new radio alarm monitor system has been installed at Ute <br />Park Pump House and the Boiler room. This system is connected to <br />two panel alarms in the Boiler room. The alarms are labeled High <br />Seepwater and Ute Park Power Failure. <br />High Seepwater: This alarm monitors the water level in <br />the Seepwater sump at Ute Park Pump House. If this alarm occurs, <br />this means that the water level in the sump has passed the start <br />probe commands for all three pumps and is still rising and the <br />pumps are not keeping up. <br />Ute Park Power Failure: This alarm monitors the existence <br />of power at the Ute Park Pump House. The Power Failure means the <br />Seepwater Pumps, Decant Pumps, Numa -Logic control system, and <br />High Seepwater Alarm do not work. There will be no pumping going <br />on at the pump house. <br />If both High Seepwater Alarm and Ute Park Power Failure <br />alarms go off at the came time, there has been a radio <br />transmission failure. The radio monitor system is set up to <br />transmit a test signal every 35 minutes. The receiver in the <br />Boiler room will check to see if it has recieved a transmission <br />every two hours. If there has been none, it will give both alarms <br />at the same time. If the unit does not clear from this condition <br />within two hours, then radio communication has totally failed and <br />the Instrumentation Department needs to be notified as soon as <br />possible. Any transmission from the pump house will reset the <br />condition. <br />This system is totally independent from the normal pump <br />house control system. <br />cc: file <br />Scott Johnson <br />Jim Mahon <br />Harry Roop <br />Carl Wood <br />Bruce Goff <br />Gib Salberg <br />Jeff Ludwig <br />Dave Lorenz <br />Toby Romero <br />A DIVISION OF AMAX INC. <br />HENDERSON MILL <br />INTER - OFFICE MEMORANDUM <br />INSTRUMENTATION FOREMAN <br />GRANT BURGER <br />Clyde Edmondson <br />Bob McCoy <br />May 17, 1991 <br />
