The AquaGuard system is a pool alarm; not a life-saving device. It should be usedalong with other safety equipment and precautions. It is intended to provide an additional level ofsecurity to your pool and/or spa.This device is not intended to replace any other safety consideration; that is, adult supervision,lifeguards, fences, gates, pool covers, locks, and so forth, and some devices may not detectgradual entry.Always observe the following safety guidelines: DO NOT allow children to operate the AquaGuard system without adult supervision. This system is a protection device that sounds an alarm to indicate a potentialEMERGENCY situation. When the alarm sounds, PROMPT ACTION by a responsible adultis essential to preventing serious injury or death. Be sure a RESPONSIBLE ADULT is present to observe swimming activities whenever theAquaGuard system is turned off.161

AquaGuard Owner’s GuideRJE Technologies, Inc.RJE Technologies, Inc.AquaGuard Owner’s Guide Hold the Remote Unit near the Detector Unit. Press the Remote Unit OK button 10 times,General Swimming Pool Safety Guidelines NEVER leave children unattended in or around the swimming pool or spa. Children underfive years of age are at GREATEST RISK for injury or death in pool-related accidents. DO NOT assume that swimming pool safety devices replace the need for adult supervision.ALWAYS have a responsible adult present to ensure safety. Give extra attention whenseveral people are swimming at the same time. Teach your children to swim at an EARLY age. Instruct ALL pool and spa users in the location and proper operation of safety features. BESURE that pool maintenance personnel understand and can properly operate theAquaGuard system. Keep RESCUE EQUIPMENT (such as a rubber life preserver and/or rescue pole)within easy reach. Keep a TELEPHONE close to the pool so it can be easily accessed in case of anemergency. Learn CPR (cardiopulmonary resuscitation) and other life-saving techniques. Keep the pool area CLEAR of toys and other obstructions. Keep the water CLEAN anduncontaminated. Keep security gates CLOSED when the pool is unattended.IF AN ACCIDENT OCCURS Get the person out of the pool as QUICKLY as possible. IMMEDIATELY call for help, and follow the advice given. Administer CPR (cardiopulmonary resuscitation) as directed or a necessary. Remove wet clothes and replace with warm covers.then pause; the Remote Unit will beep once. Press the Remote Unit OK button two times;the Remote Unit will beep twice to confirm the radio link between the Detector Unit and theRemote Unit is established.If the Remote Unit sounds one low beep, it indicates the radio link is not established. Makesure you have enabled the radio link at the Detector Unit, move the Remote Unit closer tothe Detector Unit, and repeat the procedure.Testing the SystemIt is strongly recommended that a System Test be performed periodically, using the proceduredescribed in Installation , STEP 5 on page 8.Special Considerations During WinterThe AquaGuard system will not operate if the water in your pool becomes frozen. Additionally,allowing water to freeze in the Sensor Tube can damage the system’s sensing mechanism.If your pool is located in an area in which freezing normally occurs, and you do not intend tomaintain your pool in a heated state throughout the winter season, you should remove the DetectorUnit before freezing occurs. Store the unit indoors, under cover, and re-install when the water hasthawed.Be sure to remove the batteries from the Detector Unit when placing the unit in storage for aprolonged period. Corrosion may occur if the batteries are left in the unit during storage.The Anti-Theft SystemWhen the AquaGuard Detector Unit is installed and initialized, its internal “anti-theft” system isenabled. Any attempt to dismantle or remove the Detector Unit without first turning the system offwill cause the alarm siren to sound. To turn off the “anti-theft” alarm, enter 1234*99 on the DetectorUnit keypad.Be sure to turn the system “off” before removing the Detector Unit for maintenance or storage byentering 1234*99 on the Detector Unit keypad.ABOUT THE AQUAGUARD POOL ALARM SYSTEMThe AquaGuard Pool Alarm System is designed to detect a child, pet or object of a minimum sizefalling into a pool or spa. The system monitors the movement of water caused by a fall into the poolor spa by detecting changes in water pressure. When a change in water pressure is great enoughto indicate a fall may have occurred, a siren sounds at the Detector Unit (by the pool or spa) and atthe Remote Unit (inside the house).AquaGuard technology has been extensively tested to the most rigorous standard in the world forpool alarms (AFNOR) as well as the U.S. ASTM standard. What does all this mean? It means,finally, there is a consumer-installed pool alarm system that provides excellent performancefeatures combined with high immunity to wind, rain and other water surface disruptions.215

AquaGuard Owner’s GuideRJE Technologies, Inc. Sensor Tube Check: Check the sensor tube monthly to ensure it is secure and damagefree (no cracks, breaks, deformation, etc.). Make sure the bottom of the sensor tube is 5 - 6inches (13 – 15 cm) below the surface of the water. Add water to the pool, or install aSensor Tube Extension (see System Components on page 3 for more information) ifneeded. System Test: Perform a monthly System Test to ensure the system can detect a body ofweight falling into the pool (see Testing the System on page 15 for details). Storage During Winter: If the water in your pool normally freezes during the winter months,the Detector Unit must be removed for storage before freezing occurs (see SpecialConsiderations During Winter on page 15 for more information).Replacing the BatteriesReplace the Detector Unit or Remote Unit batteries whenever a low battery is indicated (seeManaging the System on page 12 for a description of the low battery indication).Be sure to turn the system off whenever replacing the Detector Unit batteries.

AquaGuard Owner’s GuideRJE Technologies, Inc.AquaGuard Owner’s GuideRJE Technologies, Inc.Swimming Pool Alarm OperationOne AquaGuard Pool Alarm System will cover a typical 16 X 32 foot (4.9 X 9.8 meter) rectangularor kidney-shaped swimming pool. If the pool is larger, or irregularly shaped, two systems will beneeded (consult your AquaGuard dealer or call us directly with questions). When using twosystems, two Detector units can be operated by one wireless Remote Unit. A spa will require aseparate system.The AquaGuard Pool Alarm System is operated using the keypad on the Detector Unit, or the OKbutton on the Remote Unit. An audible "beep" sounds when you press a key on the Detector Unitkeypad: Short "beep" for valid entry Long "beep" when an error is detectedThe AquaGuard Pool Alarm System provides ease of use and intuitive "messaging" that lets youknow the status of the system. When you wan to use the pool, you simply enter your access codeat the Detector Unit's keypad (or from the Remote Unit) putting the system in "swim standby"mode. A short while after everyone has left the pool, the system will automatically re-arm. We feltthat it is important for you to know the status of the system (whether it is "armed" or on "swimstandby" mode) or when a low battery condition was present. For this purpose, the Detector Unithas a large red LED visible of the rear of the unit that shows system status (the Remote Unit doesthe same). Whenever the system "re-arms", an audible "beep" sounds at the Detector Unit and theRemote Unit.ASSEMBLING THE AQUAGUARD SYSTEMInstalling the BatteriesAlert and Fault Signal IndicationsIndicationConditionFall or activity inthe pool whilesystem is in“ARMED” mode.Detector UnitSiren sounds.ResponseRemote UnitSiren sounds.

Place the back cover onto the Remote Unit, and re-install the four screws.The Remote Unit must always be powered by the AC adapter. The battery is for back-up andemergency use only.Assembling the Detector Base Unit and Sensor TubeYou must assemble the Sensor Tube and Detector Unit before installing the unit at poolside.1. Remove the screw from the front fitting of the Detector Unit.Make sure the o-ring is installed on the frontfitting of the Detector Unit before installingthe Sensor Tube.2. Slide the short end of the Sensor Tube ontothe front fitting of the Detector Unit. Twist theSensor Tube back and forth slightly whileapplying firm pressure to slide the tube ontothe fitting.3. Line up the hole at the top of the Sensor Tubewith the mating hole in the front fitting of theDetector Unit; then re-install the screw tosecure the tube in place.Depending on the installation site for theDetector Unit (see Installation on page 6 fordetails), you may need to install one or moreSensor Tube Extensions. If so, simply slidethe Extension(s) onto the end of the Tube.The Tube must penetrate the water by 5-6inches (13-15 cm).INSTALLING THE AQUAGUARD SYSTEMInstallation ConsiderationsThere are a number of features that can affect AquaGuard’s “detection” abilities. Keep the followingsystem limitations in mind to ensure optimum performance of your AquaGuard system: The AquaGuard alarm must be audible from inside your home. Be sure to verify the alarmcan be heard inside your home when testing the system during installation. Care should betaken to place the Remote Unit in an accessible location, preferably plugged into a standardwall outlet. This way you know where it is, and that it is powered. Pool cleaners (sweepers) that move around the pool, climb the pool walls, and fall back intothe pool can look like a small child to the AquaGuard system. False alarms can occur if thepool sweeper hits the Sensor Tube.125
