Beaudreau Electric, Inc. AB 0 Page 3 of 4 Specificity Results: Manufacturer and evaluator claim sensors will respond to any liquid. No additional materials tested. Manufacturer's Specifications: Manufacturer states that systems require no calibration. Annual functional test required. Model 510 Discriminating Sensor and Model DFR-1 Liquid Level Switch are designed to work with Beaudreau Mode 404-4, 500, and 5000 Controllers. Model 516 Discriminating Sensor is designed to work with Beaudreau Models 500, 5000, and 512 Controllers. Model 516 Discriminating Sensor will not work with Model 404-4 Controller. Model EOS100 Discriminating Sensor is designed to work with Beaudreau Model 522 Remote Monitoring system, Model 522T Monitoring System, and ESite Monitoring System. Comments: Models 404 and 406 Liquid Level Sensors, Model DFR-1 Liquid Level Switch, and Models EOS100 and 516 Discriminating Sensors are reusable. The polymer strip used in Model 510 Discriminating Sensor is designed to be replaceable if desired. This design allows the end-user to immediately reuse the sensor by replacing the polymer strip, instead of having wait 24 to 48 hours for the polymer strip to dry out. Replacement lowers the risk of false alarms caused by the use of partially dried out polymer strips. Model 516 Discriminating Sensor is designed to be placed in a sensor well in bottom of a containment sump with Z least one other sensor mounted higher as a high-water cut-off. Both Models 510 and 516 Discriminating Sensors were not evaluated for the ability to detect a layer of hydrocarbc on water. Model EOS100 has 5 sensing points that can sense fuel or water over a 3.5-inch range. The highest sensor(level acts as a high level switch. If water is detected at level 5, a fuel alarm will be triggered instead of a water alarm. If fuel is detected at any of the levels, a fuel alarm will be triggered. The output from the system can be used to shut down the turbines when fuel is present or when water reaches tF high level switch. Model 522 Remote Monitoring System: Evaluation indicates that when threshold level of Model 406 Liquid Level Sensor, and Models EOS100, 510 and 51E Discriminating Sensors was reached, Model 522 Remote Monitoring System produced (1) an audible and visual ala and (2)an output signal that was recognized by a Veeder-Root TLS-350 Monitoring System. The TLS-350 Monitoring System produced an alarm within 10 seconds, and displayed and printed a notice of alarn and alarm time. Manufacturer states that the output signal produced by Model 522 Remote Monitoring System can be recognized t other monitoring systems designed to detect this output signal. Model 522 Remote Monitoring System was evaluated only using the Veeder-Root TLS-350 Monitoring System. Model 522T Monitoring System: Evaluation indicates that when threshold level of Model 406 Liquid Level Sensor, and Models EOS100, 510 and 51E Discriminating Sensors was reached, Model 522T Monitoring System will generate a visual (LCD readout and LED "alarm" lamp)and audible alarm and also open up to three normally closed relay contacts. By using a Model 522R Relay, the system can use these normally closed relay contacts to control power to turbine pumps. Alternatively, the normally closed relay contacts can be used to send fuel alarm information to a Veeder-Root TLS- for both positive shutdown and additional alarm notification (such as a printout showing the date and time that a release has occurred). ESite Monitoring System: Uses an array of EOS-100 fiber optic discriminating sensors to provide for continuous monitoring of interstitial spar or sumps. Detection of liquid triggers audible and visual alarms on the ESite user interface screen. Alarm informa can also be transmitted to remote locations through network or internet connections.
