The SmartCover® system works by taking a distance measurement every 6 minutes <br />using the DSM (ultrasonic sensor). If the water is below the alarm level, the <br />SmartCover® logs every other distance reading and sends it to the historical server <br />every hour for long term trending. If the water level is above the alarm level, an <br />alarm notification is sent directly to the users. It is a 24 hour a day, 7 day a week <br />system. <br />Below is a typical graph from the City of Santa Ana secure web page. It can be <br />seen that everything is normal and then there is a high water level alarm. The <br />bottom of the sensor is 64 inches from the manhole cover and the alarm is set for 74 <br />inches below the manhole cover. <br />The City of Santa Ana will receive alarms through cell phone or pagers via Short <br />Message Service (SMS), or Smart Phones and emails via email messaging. A <br />direct - from - satellite handheld system is available upon request for highly critical <br />communications in case of massive power loss upon request. <br />A LEVEL MEASUREMENT IS TAKEN EVERY 6 MINUTES AND UPDATES THE <br />DATA ON THE SERVER EVERY HOUR. IN THE EVENT OF A HIGH WATER <br />EVENT, THE ALARM IS SENT THE NEXT TIME A LEVEL MEASUREMENT IS <br />MADE. IN THIS CASE THE LONGEST TIME BETWEEN THE TIME THE WATER <br />REACHES THE ALARM LEVEL AND WHEN THE ALARM SOUNDS IS 5 <br />MINUTES AND 59 SECONDS. <br />THIS TYPE OF OPERATION WOULD RESULT IN A POWERPACK LIFE OF 12 <br />MONTHS. <br />15 <br />Hadronex Inc. 2067 Wineridge PI, Suite E, Escondido, CA, 92026 <br />25L -24 <br />2012 - 05.0413:56 • 2012.05. 1213:56 Distance from Manhote Cover <br />Aiarm 5eitioint =74 <br />Sensor Position 64 <br />60 In <br />70 {n <br />75 in <br />,.....,.. <br />......... <br />........... <br />..... <br />.�.. <br />,......., <br />......w.:« <br />.,....,.,.._..... <br />80 in <br />85 In <br />90 In <br />95 Irfy� <br />N <br />a <br />6 <br />b <br />i4 <br />r+ <br />C1 iti <br />C5 W <br />fJ <br />9 <br />iY t5 <br />H CS <br />N <br />M <br />N <br />N N <br />N <br />N N <br />iV <br />(V <br />N <br />N <br />N <br />iV <br />tV <br />N <br />N <br />N <br />to <br />u, <br />,h <br />,n <br />u'x ui <br />u'w <br />n5 <br />vh <br />us <br />J, <br />�n <br />CJ <br />Ct <br />4 b <br />Gt <br />O f? <br />K� <br />i� <br />tl <br />t7 <br />Q <br />4 <br />53 <br />C3 <br />Q <br />4 <br />The City of Santa Ana will receive alarms through cell phone or pagers via Short <br />Message Service (SMS), or Smart Phones and emails via email messaging.
