Regarding the operation when the alarm hold setting is activated
When the alarm hold setting is activated, the alarm status is held until the cancel switch is pressed.
Electric power failure or power-off returns the contact operation status to that when the power source is shut off.
When alarm holding is not set, refer to Drawing -15 and Operation Chart 1.
Regarding the Alarm Indicator LED
The Alarm Indicator LED does not maintain alarm status. The Alarm Indicator LED goes out when the system detects
recovery from water leakage status and break status.
If the Alarm Indicator LED continues to flash even after the water leakage sensor is wiped with rags etc., this indicates that
water leakage may occur at multiple locations.
After completely drying the water leakage sensor at the location that the indicator displays, press the alarm cancel switch.
* If drying is insufficient, deviation may occur between the water leakage location displayed after the alarm cancel switch is
pressed and the actual water leakage location.
8. Indication of Detector Number
Related settings are necessary to be carried out if it is expected to indicate number on the indicator, in the case of
multiple indicators are used together. Turn the Detector Number Setting Switch and select a number that you want to
indicate. (Refer to Attached Drawing 19)
The detector number is indicated on the leftmost 7-segment LED.

9. Detection Sensitivity Setting
Changing operational setting switches changes the detection sensitivity level.
(Refer to Drawing 20.)
*The water leakage sensor detects water leakage even it is caused by only a small amount of water (condensation, for
example). Therefore, if the sensor is installed in a location subject to high temperature and high humidity, set the
sensitivity level lower.
* In the case in which it is necessary to detect fluid with high electrical resistance, such as pure water, in an environment where
the temperature and humidity are stable, such as a clean room, it is recommended to set the sensitivity level high.
