5-2 Ground Connection
Be sure to ground for noise prevention.
5-3 Water Leakage Sensor Connection
The structure and configuration of the water leakage sensor (AD-LS Sensor) used for the Water Leakage
Location Detector (AD-AS-1LDMA) are shown in Drawing 4 and Table 1.
* Shapes and functions of each wire vary, so extra care should be taken when connecting it to the detector.
(Refer to Drawing 5.)
Incorrect wiring will result in inaccurate indication of water leakage locations or break alarm output.
* While carrying out wiring, make sure that the power is switched off.
