Water Leakage Detector
AD-AS-1AM
Instruction Manual
We thank you for using our Model AD-AS-1AMWater Leakage Detector.
Be sure to read the following instructions before installing, adjusting and using the detector.
Cautions in installing and handling the detector
 Use the detector in a working environment with a temperature range between -10˚C, and 50˚C and a
humidity range between 35%RH and 85%RH.
 Avoid using the detector near sources of vibration, harmful gas, or strong electromagnetic induction.
 For connection to the power supply, avoid using receptacles (sockets); use fixed wiring connection.
 Use our products for sensors and break detection terminals (excepting AD-LS sensors and ZT-L2
products).
 Be sure to affix the insulating sheet to the terminal block, fix the outer cover and check detector operation.
 Smoke or abnormal sound occurrence with the power indication LED turned off indicates detector failure.
Switch off the main power breaker, stop using the detector and contact us.
Maintenance and inspection
 Check at least once every six months to confirm that detector is operating normally. At the same time,
check to see that screws on different parts of the detector are tightened properly.
 Be careful of water-repellant substances, such as oil, adhering to sensor surface and interior; this may
interfere with correct detector operation.
 If a sensor is stained with dirty water, replace it with a new one.
Guarantee
This detector is delivered to customers after strict quality control and inspection. Should it fail under normal
usage, we will repair it free of charge or replace it during the warranty period (within one year of delivery).
* Detector failure due to natural disaster, fire, unauthorized repair, dropping or damage after purchase is not
covered by the warranty.
Ask place of purchase for the guarantee document.
When asking for the guarantee document, provide detector serial number (indicated on label on right-side
face of the right-side terminal block).
If you have any questions about handling the detector, contact:
Handling Method
 Typical Configuration of Water Leakage Detection System
* Using vinyl tape or similar material, insulate the connections of water leakage sensor break detection
terminals and instrumentation wires (it is recommended that they be housed in a box.), and fix them at a
location above the floor to keep them from getting wet.

 Checking power-on
Power-on causes the power indicator LED (yellow) to light.
 Checking water leakage detection function
 Checking water leakage detection test function:
Pressing buzzer stop and reset buttons simultaneously for three seconds or more causes output of
simulated water leakage alarms (water leakage indicator LED flashing output, buzzer sounding
output,and water leakage alarm contact output).
 Checking water leakage detection function with water:
By allowing tap water to drip on the sensor, you can check how well the sensor detects water
leakage. Wipe off water with dry cloth after check to restore sensor to operational state for water
leakage detection.
 Checking of the break detection function
 Checking break detection test function:
You can check break detection function without removing break detection terminal or sensor.
Pressing buzzer stop and reset buttons simultaneously for three seconds or more causes output of
simulated water leakage alarm; pressing both of them for three seconds after this causes output of
simulated break alarms (break indicator LED (green) flashing output; buzzer sounding output; break
alarm contact output).
Note: Break alarm is also output when the break detection function is "not activated."
 Checking actual break detection function:
Remove outer cover
insulating sheet and the terminals connected to sensor (I) on the terminal block
,
to check actual break detection function.
After checking, reattach terminals, insulating sheet and outer cover.
 Buzzer stop button
If this button is pushed while buzzer is sounding, buzzer stops sounding until next alarm.
 Reset button
 If reset button is pushed while the alarm is being held with alarm hold setting activated, alarm output is
reset.
 If reset button is pushed with alarm hold setting not activated or under normal conditions, lamp test can
be performed.
All LEDs are lit and buzzer is sounds (with monotonous tone). Under this condition, control output
contacts do not operate.

<<<Important safety instructions>>>
Erroneous operation of this water leakage detector not complying with the warning labels or the following
warnings may lead to fatal accident, serious injury, electric shock, fire, or detector failure.
Strict Prohibitions
 Never modify or disassemble the detector.
 Observe ratings of power supply voltage and contact capacity.
 Allow only persons responsible for handling this product to perform installation work on it or to adjust
or inspect it with the outer cover opened.
 After the detector is installed, do not leave it with the cover open, except for inspection and
maintenance purposes.
 Do not touch any internal component with wet hands.
 When performing maintenance on the product, avoid using organic solvent. Use dry wiping rags or a
small amount of diluted neutral detergent.
Note: Be careful not to allow detergent solution to remain on the sensor.
Checkpoints
 Check detector supply voltage and rated voltage before installing.
 When installing and electrically connecting the detector, follow the instructions in the instruction
manual.
 When inspecting and maintaining the detector, follow the instructions in the instruction manual.
 When using control output contacts, check the contact rated load in the instruction manual.
Do not install the detector in the following locations!
 Locations easily accessible to the general public
 Locations close to sources of vibration, organic gas or strong electromagnetic induction.
 Locations with much waste and dust
 Locations where there is possibility of water leakage and temperature and humidity are high

* "Alarm hold" denotes function of holding alarm until reset button is pressed.
* "Fail-safe setting" denotes setting to reverse contact logic so that system can judge detector power
supply OFF state to be an abnormality. This setting reverses action of N.O. (Normally Open) contacts
and N.C. (Normally Close) contacts. Under this setting, power-on causes contacts to operate.

Our suggestions: When detecting a low conductivity liquid or using a low-sensitivity water leakage
sensor (such as AD-FH), raise detection level; conversely, when detecting a high conductivity liquid or
installing detector in a high-temperature, high-humidity environment, lower detection level.
