Signal grounding electrode can short connect GND.
When organize a network, it needs connecting Detector in accordance with wire color.
VIII. Install Caution
Special Explanation: only if it forms a return circuit grounding connection system, it could directly install
and use. Otherwise, firstly it needs to set up an auxiliary grounding connection nearby to form a return circuit,
then to install the Detector.
1. Install the Detector to grounding down lead, and grounding down lead needs to unbuckle buckle,
convenient for product maintenance latterly. Installation must be waterproof, rainproof, anti-theft and
breakage-proof and so on in the open air.
2. Notice direction, try to be vertical and wire port downwards.
3. Notice height.
4. Deploy power supply and communication wire on the basis of field and distance.
5. Power supply wire

t work.
IX. Power Supply Way Choice
1. AC adapter converts power supply
’
s 220V AC into 6-9V DC, which can supply Detector.
2. 2 pieces standby batteries for alternate use.
3. As the picture below, solar cell panel supply is suitable for the places where can't get electricity. Solar cell
