SAFETY PRECAUTIONS
Important! The AquaGuard system is a pool alarm; not a life-saving device. It should be used
along with other safety equipment and precautions. It is intended to provide an additional level of
security 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 detect
gradual 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 potential
EMERGENCY situation. When the alarm sounds, PROMPT ACTION by a responsible adult
is essential to preventing serious injury or death.
•Be sure a RESPONSIBLE ADULT is present to observe swimming activities whenever the
AquaGuard system is turned off.

AquaGuard Owner’s Guide RJE Technologies, Inc.

General Swimming Pool Safety Guidelines
•NEVER leave children unattended in or around the swimming pool or spa. Children under
five 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 when
several 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. BE
SURE that pool maintenance personnel understand and can properly operate the
AquaGuard 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 an
emergency.
•Learn CPR (cardiopulmonary resuscitation) and other life-saving techniques.
•Keep the pool area CLEAR of toys and other obstructions. Keep the water CLEAN and
uncontaminated.
•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.
ABOUT THE AQUAGUARD POOL ALARM SYSTEM
The AquaGuard Pool Alarm System is designed to detect a child, pet or object of a minimum size
falling into a pool or spa. The system monitors the movement of water caused by a fall into the pool
or spa by detecting changes in water pressure. When a change in water pressure is great enough
to indicate a fall may have occurred, a siren sounds at the Detector Unit (by the pool or spa) and at
the Remote Unit (inside the house).
AquaGuard technology has been extensively tested to the most rigorous standard in the world for
pool 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 performance
features combined with high immunity to wind, rain and other water surface disruptions.

•Hold the Remote Unit near the Detector Unit. Press the Remote Unit OK button 10 times,
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 the
Remote Unit is established.
If the Remote Unit sounds one low beep, it indicates the radio link is not established. Make
sure you have enabled the radio link at the Detector Unit, move the Remote Unit closer to
the Detector Unit, and repeat the procedure.
Testing the System
It is strongly recommended that a System Test be performed periodically, using the procedure
described in Installation , STEP 5 on page 8.
Special Considerations During Winter
The 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 to
maintain your pool in a heated state throughout the winter season, you should remove the Detector
Unit before freezing occurs. Store the unit indoors, under cover, and re-install when the water has
thawed.
Be sure to remove the batteries from the Detector Unit when placing the unit in storage for a
prolonged period. Corrosion may occur if the batteries are left in the unit during storage.
The Anti-Theft System
When the AquaGuard Detector Unit is installed and initialized, its internal “anti-theft” system is
enabled. Any attempt to dismantle or remove the Detector Unit without first turning the system off
will cause the alarm siren to sound. To turn off the “anti-theft” alarm, enter 1234*99 on the Detector
Unit keypad.
Be sure to turn the system “off” before removing the Detector Unit for maintenance or storage by
entering 1234*99 on the Detector Unit keypad.

AquaGuard Owner’s Guide RJE Technologies, Inc.

•Sensor Tube Check: Check the sensor tube monthly to ensure it is secure and damage-
free (no cracks, breaks, deformation, etc.). Make sure the bottom of the sensor tube is 5 - 6
inches (13 – 15 cm) below the surface of the water. Add water to the pool, or install a
Sensor Tube Extension (see System Components on page 3 for more information) if
needed.
•System Test: Perform a monthly System Test to ensure the system can detect a body of
weight 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 Special
Considerations During Winter on page 15 for more information).
Replacing the Batteries
Replace the Detector Unit or Remote Unit batteries whenever a low battery is indicated (see
Managing 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. If the unit is
not turned off, the unit’s Anti-Theft System will sound the alarm (see The Anti-Theft System
on page 15 for more information).
Detector Unit:
1. Press 1234*99 on the Detector Unit keypad to turn the system “off.”
2. Remove the two screws at the rear of the Detector Unit. Lift up slightly at the rear of the

Swimming Pool Alarm Operation
One AquaGuard Pool Alarm System will cover a typical 16 X 32 foot (4.9 X 9.8 meter) rectangular
or kidney-shaped swimming pool. If the pool is larger, or irregularly shaped, two systems will be
needed (consult your AquaGuard dealer or call us directly with questions). When using two
systems, two Detector units can be operated by one wireless Remote Unit. A spa will require a
separate system.
The AquaGuard Pool Alarm System is operated using the keypad on the Detector Unit, or the OK
button on the Remote Unit. An audible "beep" sounds when you press a key on the Detector Unit
keypad:
•Short "beep" for valid entry
•Long "beep" when an error is detected
The AquaGuard Pool Alarm System provides ease of use and intuitive "messaging" that lets you
know the status of the system. When you wan to use the pool, you simply enter your access code
at 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 felt
that it is important for you to know the status of the system (whether it is "armed" or on "swim
standby" mode) or when a low battery condition was present. For this purpose, the Detector Unit
has a large red LED visible of the rear of the unit that shows system status (the Remote Unit does
the same). Whenever the system "re-arms", an audible "beep" sounds at the Detector Unit and the
Remote Unit.
ASSEMBLING THE AQUAGUARD SYSTEM
Installing the Batteries
It is recommended that you use “long life” Alkaline batteries in both the Detector Unit and the
Remote Unit.
Detector Unit:
1. Remove the two screws at the rear of the Detector Unit.
2. Turn the unit upside down. Lift up slightly on the base
plate (see photo). Slide the base plate toward the back
of the unit, and remove the base plate from Detector
Unit housing.
3. Install four “D” size batteries in the battery compartment.
4. Slide the tab on the front of the base plate into the slot in
the nose of the Detector Unit housing; then lower the
base plate into place.
5. Reinstall the two screws at the rear of the Detector Unit.
6. The system will now start the arming sequence. The
Detector Unit will emit 10 short beeps, followed by one
long beep, indicating that the system is armed. The rear
LED will begin flashing.

Detector Unit; then re-install the screw to
secure the tube in place.
Depending on the installation site for the
Detector Unit (see Installation on page 6 for
details), you may need to install one or more
Sensor Tube Extensions. If so, simply slide
the Extension(s) onto the end of the Tube.
The Tube must penetrate the water by 5-6
inches (13-15 cm).
INSTALLING THE AQUAGUARD SYSTEM
Installation Considerations
There are a number of features that can affect AquaGuard’s “detection” abilities. Keep the following
system 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 alarm
can be heard inside your home when testing the system during installation. Care should be
taken to place the Remote Unit in an accessible location, preferably plugged into a standard
wall 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 into
the pool can look like a small child to the AquaGuard system. False alarms can occur if the
pool sweeper hits the Sensor Tube.

AquaGuard Owner’s Guide RJE Technologies, Inc.

•Water movement caused by high velocity/high flow filtration systems can affect
AquaGuard’s “detection” sensitivity.
•Extreme environmental conditions (strong wind, heavy rain) can affect AquaGuard’s
“detection” sensitivity. The time required to return to “armed” mode under these conditions
may be longer than normal.
•In order to properly detect and signal a potential, the AquaGuard Detector Unit must be
installed within 22 feet (6.7 meters) of all possible fall locations. Larger pools should be
equipped with an additional Detector Unit to meet this requirement.
•Pools with perimeter overflow are not compatible with AquaGuard.
•Vanishing edge (Infinity or zero edge) pools typically require two AquaGuard Detector Units.
Tools Required
You will need the following tools and materials to install and test the AquaGuard system:
•Marking pen •Flat-head screwdriver
•Drill •2.5 (19.5 liter) gallon water container
•¼” (7 mm) Masonry drill bit •Rope
•Phillips-head screwdriver
Installation
STEP 1 - Choose the Detector Unit Installation Site
•The Detector Unit must be installed within 22 feet (6.7 meters) of all possible fall
locations, and must have direct view of the rest of the pool. In most cases, this location
will be at the middle of the longest side of your pool. Typical examples of installation are
shown below.
22 FEET

whenever you wish to use your swimming pool. When the
AquaGuard system is in “SWIM” Mode, activity in the pool will
not trigger the alarm. Be sure a RESPONSIBLE ADULT is
present to observe swimming activities whenever the system
is place in “SWIM” Mode.
To place the system in “SWIM” Mode:
•From the Detector Unit: Enter your Access Code on the
Detector Unit keypad.
•From the Remote Unit: Press the Remote Unit OK
button three times.

(6.7 METERS)
22 FEET
(6.7 METERS)
•Assemble and position the Detector Units as described in STEP 1 and STEP 2.
•Establish the radio link between the Remote Unit and both Detector units as described
in STEP 4.
Be sure to set both Detector Units to the same radio channel; e.g., press 1234*7001 on
Detector Unit 1 and Detector Unit 2.
OPERATING THE AQUAGUARD SYSTEM
Refer to Controls and Indicators on page 3 for a description of the controls and indicators used to
operate and monitor your AquaGuard system. Once your AquaGuard system has been installed,
and the radio link established, you can control and monitor the system from either the Detector Unit
or from the Remote Unit.
A “Quick Reference” guide to operating your AquaGuard system is provided on the back cover of
this manual. For detailed operating instructions, see the following paragraphs:
•Refer to Setting System Parameters on page 10 for instructions on setting user-configurable
operating parameters for your AquaGuard system.
•Refer to Operating the System on page 11 for procedures to switch system operating
modes, cancel an active alarm, and turn the system ON and OFF.
•Refer to Managing the System on page 12 for descriptions of “alert” and “fault” indications
and corrective actions.
Setting System Parameters
The AquaGuard system has several user-configurable parameters. Each parameter has a factory-
set default value. You can leave these parameters at their default values, or modify the parameters
to “personalize” your system. The following table shows a list of user-configurable system
parameters, the key combination used to modify the parameter, and the allowable values for each
parameter.
All user-configurable parameters must be modified at the Detector Unit. Refer to Controls and
Indicators on page 3 for general instructions on using the Detector Unit keypad.

STEP 2 - Position the Detector Unit at the Chosen Site
•Place the Detector Unit at the installation site so the Sensor Tube extends into the
water.
•Make sure the bottom of the Sensor Tube is between 5 - 6 inches (13 – 15 cm) below
the water’s surface.
If the Sensor Tube is too short, install a Tube
Extension on the Sensor Tube to meet the
required depth (see Assembling the Detector
Base Unit and Sensor Tube on page 5 for
details).
If the Sensor Tube is too long, it may be
necessary to cut the Tube to the proper length.
BE SURE the water in the pool is at its normal
level before measuring. Fill the pool if
necessary. BE SURE to measure carefully
before cutting the Tube.
If the tube end is at less than 5 inches (15 cm), unwanted alarms may occur. If the tube
end is deeper than 6 inches (15 cm), the unit’s “detection” sensitivity will be lessened.
STEP 3 - Choose a Location for the Remote Unit
•The Remote Unit must be placed within 150 feet of the Detector Unit.
The Selected location should have as few obstructions between the Remote Unit and
the Detector Unit as possible. Interior and exterior walls or other obstacles will reduce
the range of the Remote Unit.
•Choose a location that will allow the Remote Unit alarm to be heard throughout the
house.
•Choose a location that is near an AC outlet to allow the Remote Unit to be powered by
the AC adapter.
The Remote Unit must always be powered by the AC adapter. The battery is for back-up
and emergency use only.
STEP 4 - Establish the Radio Link
The AquaGuard system uses a radio transmitter/receiver to allow communication between
the Detector Unit and the Remote Unit. You must establish the radio link to use the Remote
Unit to monitor and control your AquaGuard system.
•Ensure that the Detector Unit is on (the red LED on the rear of the Unit flashes slowly
when the Unit is on).
•Press 1234*7001 on the Detector Unit keypad to enable the radio link.
•Hold the Remote Unit near the Detector Unit. Press the Remote Unit OK button 10
times, then pause; the Remote Unit will beep once. Press the Remote Unit OK button
two times; the Remove Unit will beep twice to confirm the radio link between the
Detector Unit and the Remote Unit is established.

If the Remote Unit sounds one low beep, it indicates the radio link is not established.
Make sure you have enabled the radio link at the Detector Unit, move the Remote Unit
closer to the Detector Unit, and repeat the procedure.
STEP 5 - Test the System for Detection
Prepare a Test Simulator
•Fill a 2.5-gallon (19.5 liter) water container with enough water to weigh approximately 15
pounds (6.8 kg).
•Tie a 6-foot (1.8 meter) length of rope to the container handle.
Perform Test One
•Make sure both the “ARMED” LED on the Detector Unit and the “green” LED on the
Remote Unit are on.
If the LEDs are not on, the system is not “armed”. Allow additional time for the water in
the pool to settle enough to allow the Detector Unit to “arm.”
•Place the test simulator on the edge of the pool, 4 - 6 feet (1.2 – 1.8 meters) from the
Detector Unit.
•Hold the rope, and roll the test simulator into the pool. Both the Detector Unit and the
Remove Unit alarms should sound.
If the alarms do not sound, it may be necessary to change the location of the Detector
Unit.
Reset the System
•Press any key on the Detector Unit keypad to turn the alarm off.
•Remove the test simulator from the pool.
•Wait 6 to 10 minutes to allow the unit to automatically “re-arm.” When the water has
stabilized and the unit is “armed”, the “ARMED” LED will blink and the beep sequence
will repeat.
Perform Test Two
•Make sure both the “ARMED” LED on the Detector Unit and the “green” LED on the
Remote Unit are on.
If the LEDs are not on, the system is not “armed”. Allow additional time for the water in
the pool to settle enough to allow the Detector Unit to “arm.”
•Place the test simulator on the edge of the pool, at the point farthest from the Detector
Unit, not to exceed 22 feet (6.7 meters).
•Hold the rope, and roll the test simulator into the pool. Both the Detector Unit and the
Remote Unit alarms should sound.
If the alarms do not sound, it may be necessary to change the location of the Detector
Unit.

Reset the System
•Press any key on the Detector Unit keypad to turn the alarm off.
•Remove the test simulator from the pool.
•Press 1234*99 on the Detector Unit keypad to turn the system “off.”
The Detector Unit's "anti-theft" alarm will sound if the Unit is dismantled while the system is
on. Enter 1234 on the Detector unit keypad to deactivate the "anti-theft" alarm.
STEP 6 - Mount the Detector Unit Base Plate
•Mark the location of the Detector Unit on the pool deck. Remove the Detector Unit from
the pool.
•Remove the two screws at the rear of the Detector Unit, and slide the base plate off the
Detector Unit housing. Remove the batteries from the Detector Unit to prevent the "anti-
theft" alarm from activating.
•Place the base plate at the previously marked position. Use a permanent marker to
mark the locations of the three holes in the base plate. Set the base plate aside.
•Use a drill and ¼”(7 mm) masonry bit to drill three holes, ¾” (19 mm) deep, at the
marked locations.
Be sure to drill the holes straight and perpendicular to the surface of the pool deck. If the
hoes are drilled at an angle, the base plate may not secure properly.
•Install one plastic insert (provided) into each of the drilled holes.
•Place the base plate on the pool deck over the drilled holes. Secure the base plate to
the pool deck with the three screws provided.
•Re-install the batteries in the Detector Unit. Place the Detector Unit housing over the
base plate. Lift up slightly on the rear of the housing. Slide the tab on the front of the
base plate into the slot in the nose of the Detector Unit housing; then lower the housing
onto the base plate.
•Re-install the two screws at the rear of the Detector Unit.
STEP 7 - Confirm the System is On and Armed
•Wait 6 to 10 minutes to allow the unit to automatically “arm.” When the water has
stabilized and the unit is “armed”, the “ARMED” LED will blink and the beep sequence
will repeat.
•Establish the radio link as described in step 4.
•Repeat the tests described in step 5.
