Beaudreau Electronics, Inc. AB <br />10 0 <br />system and Model 522T Monitoring ng System. <br />Models 404 and 406 Liquid Level Sensors and Models EOS100 and 516 Discriminating Sensors are <br />reusable. <br />The polymer strip used in Model 510 Discriminating Sensor is designed to be replaceable if desired. <br />This design allows the end-user to immediately reuse the sensor by replacing the polymer strip, instead of <br />having to wait 24 to 48 hours) for the polymer strip to dry out. <br />Replacement lowers the risk of false alarms caused by the use of partially dried out polymer strips. <br />Model 516 Discriminating Sensor is designed to be placed in a sensor well in bottom of a containment <br />sump with at least one other sensor mounted higher as a high-water cut-off. <br />Both Models 510 and 516 Discriminating Sensors were not evaluated for the ability to detect a layer of <br />hydrocarbon on water. <br />Model EOS100 has 5 sensing points that can sense fuel or water over a 3.5 -inch range. The highest <br />sensor (level 5) acts as a high level switch. <br />If water is detected at level 5, a fuel alarm will be triggered instead of a water alarm. <br />If fuel is detected at any of the levels, a fuel alarm will be triggered. <br />The output from the system can be used to shut down the turbines when fuel is present or when water <br />reaches the high level switch. <br />Model 522 Remote Monitoring System: <br />Evaluation indicates that when threshold level of Model 406 Liquid Level Sensor, and Models EOS100, 510 <br />and 516 Discriminating Sensors was reached, Model 522 Remote Monitoring System produced (1) an <br />audible and visual alarm and (2) an output signal that was recognized by a Veeder-Root TLS -350 <br />Monitoring System. <br />The TLS -350 Monitoring System produced an alarm within 10 seconds, and displayed and printed a notice <br />of alarm and alarm time. <br />Manufacturer states that the output signal produced by Model 522 Remote Monitoring System can be <br />recognized by other monitoring systems designed to detect this output signal. <br />Model 522 Remote Monitoring System was evaluated only using the Veeder-Root TLS -350 Monitoring <br />System. <br />Model 522T Monitoring System: <br />Evaluation indicates that when threshold level of Model 406 liquid Level Sensor, and Models EOS100, 510 <br />and 516 Discriminating Sensors was reached, Model 522T Monitoring System will generate a visual (LCD <br />readout and LED "alarm" lamp) and audible alarm and also open up to three normally closed relay <br />contacts. <br />By using a Model 522R Relay, the system can use these normally closed relay contacts to control power to <br />turbine pumps. <br />Alternatively, the normally closed relay contacts can be used to send fuel alarm information to a <br />Veeder-Root TLS -350 for both positive shutdown and additional alarm notification (such as a printout <br />showing the date and time that a release has occurred). <br />Beaudreau Electronics, Inc. <br />23 Industrial Drive <br />Waterford, Cr 06285-9715 <br />Tel: (860) 443-6570 <br />E-mail: customerservice@beaudreauelectric.com <br />URL: www.beaudreauelectric.com <br />Evaluator: Ken Wilcox Associates <br />Tel: (816) 443-2494 <br />Date of Evaluation: 07/20/94 <br />(Revised 03/02/01, 09/23/02, 12/23/02, <br />08/28/03, 12/01/03) <br />3 of 4 5/26/2004 3:27 PM <br />
