Warnings

<<<Important safety instructions>>>

Warning

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.

Never modify or disassemble the detector.

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.

Observe ratings of power supply voltage and contact capacity. * Application of AC 200 V to the AC 100 V terminal will destroy the detector.

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.

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.

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

Strict Prohibitions

Checkpoints

Do not install the detector in the following locations!

1. Scope This specification document is applicable to the single-circuit-use water-leakage detector, model AD–AS–1AM(RoHS-directive-compatible), developed to protect computer rooms, important facilities, warehouses, valuable documents, and similar objects from unforeseeable water leakage.

2. Overview of the detector

2–1 Internal Configuration of Detector

Fig. 1 Detector configuration

2-2 Typical configuration of detecting system

Fig.2 Typical detecting system configuration * Make a secure connection from the water leakage sensor to the instrumentation line and to the

break detection terminal; insulate connections with vinyl tape or similar material. It is recommended that the connections and the break detection terminal be housed in a joint box to be installed in a location safe from submersion in water.

* The factory default setting is the value at which our water leakage sensor*1 can properly detect the presence of common city water. *1: Line sensors (AD, AD-R, AD-H, and FR-AD): within 100 m; point sensor (AD-PA)

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

Break judgment level 30 kΩ ±20% or more Break recovery level 25 kΩ ±20% or less

Function of the outer cover operating button

Function Buzzer stop button

Reset button Action

Buzzer stop ¾ Pressing this button when the alarm is on stops the buzzer temporarily. * A new alarm causes the buzzer to sound again.

Alarm hold cancel ¾ This button cancels the alarm contact output and buzzer when alarm is being held as a result of activation of the alarm hold setting.

Lamp test ¾ Pressing this button causes all indicator lamps to light and the buzzer to sound when the alarm hold setting is not activated and under normal condition.

Water leakage/ break simulation test

Pressing this button for three seconds or longer outputs the alarm for a simulated water leakage detection state; three seconds later, the alarm for a simulated break is output.

Outer cover LED indication Power indicator lamp, yellow: One (stays lit) Water leakage indicator lamp, red: One (flashes) Break indicator lamp, green: One (flashes)

Alarm buzzer Water leakage: sound varies in frequency between 4 kHz and 2 kHz (repeated howling); break: sound alternates between 4 kHz and 2 kHz (repeated pee-poh sound)

Function setting and adjustment With the outer cover open, the following settings can be input using the internal switches and knobs:

Setting/adjustment item Setting/adjustment range Factory default setting
