1 Issues to pay attention to during the installation of the electric security fencing

(1) Do not use the electric security fencing around flammable or explosive materials. When using it in special circumstances, maintain a safe distance.

(2) The electric security fencing host cannot be installed in damp, excessively high or low temperature environments.

(3) Do not install during thunderstorms.

(4) The main chassis is installed at a height that is easy to repair and maintain.

(5) Is there a strong interference source (such as high-frequency equipment such as radio transmitters) near the installation location of the electric security fencing? If so, it must be indicated in the construction drawing that the signal line must use shielded twisted pair cables.

(6) Once there is an abnormal situation with the electric security fencing, the power should be cut off first, and professional installation or maintenance personnel should be notified. Do not dismantle or repair it yourself.

(7) Users of electric security fencings must have knowledge of electrical safety and electric shock rescue, undergo professional training, and be familiar with the correct use of them.

2 Common faults and troubleshooting methods during the operation of the electric security fencing

Fault diagnosis: Disconnect the high-voltage insulated wires connecting the electric security fencing host and the front end, and connect the various wiring terminals of the electric security fencing host separately with ordinary insulated wires, so that the electric security fencing host can operate in a no-load working state. If the fault persists, it may be a problem with the electric security fencing host. If the electric security fencing host is normal, the fault occurs in the front-end. Please troubleshoot according to the following common faults.

(1) Fault phenomenon: The status bar of the electric security fencing host displays abnormally.

Judgment:

There is cable leakage or internal breakage of high-voltage insulation wire in the front fencing, causing ignition or leakage at the alloy wire connection.

Exclusion method:

A. Front end: Use a multimeter to segment test the resistance values at each joint to see if they are within the normal range. Otherwise, the metal alloy wire should be replaced. At the same time, check the resistance of the high-voltage line to see if there is excessive resistance caused by breakage or high-voltage ignition. If so, replace the high-voltage line.

B. Identify the metal brackets or conductors of the fencing that are too close, correct the distance between them, and maintain good insulation.

C. The power supply voltage of the electric security fencing host is too low (it is required that the power supply voltage should not be lower than 190V).

(2) Fault phenomenon: The electric security fencing host continues to alarm.

Judgment:

There are open circuits, short circuits, and ground short circuits in the front end.

Exclusion method:

A. Front end open circuit condition: Use a multimeter to check the continuity of the circuit and make a judgment.

B. Front end short circuit condition: Use a multimeter to check if there is a series short circuit in the circuit.

C. Front end ground short circuit situation: Use a multimeter to check the circuit ground resistance (in relatively humid weather). If the ground resistance is small, there is a ground short circuit situation.

(3) Fault phenomenon: The electric security fencing host is not working or there is no display.

Judgment:

It is possible that the power supply of the electric security fencing host is too low or the electric security fencing host is burnt out.

Exclusion method:

Determine whether the power supply of the electric security fencing host is normal. If the power supply is normal, the electric security fencing host may be burned out (due to high power supply voltage or lightning strikes).

(4) Fault phenomenon: The electric security fencing host is in an alarm state, but the linked alarm device does not sound an alarm.

Judgment:

Fault in the linkage alarm device or abnormal output of the electric security fencing host linkage.

Exclusion method:

Use a multimeter to test whether the electric security fencing host linkage output interface (normally open/normally closed) switches normally. If the switch is normal, it is a malfunction of the linkage device, otherwise it is a malfunction of the electric security fencing host linkage output module.

(5) Fault phenomenon: After troubleshooting the above 4 fault phenomena, the electric security fencing host still alarms.

Judgment:

The construction personnel did not operate according to the specifications during construction, and the accessories were installed incorrectly, resulting in abnormal operation of the electric security fencing host.

Exclusion method:

A. Strictly follow the specifications provided by the manufacturer for construction.

B. Eliminate incompatible products (such as high-voltage insulated wires with low voltage resistance).

3 Daily operation and maintenance essentials of the electric security fencing

(1) Power outage maintenance should be carried out every three months. Maintain a clean and well-ventilated working environment for the electric security fencing host, and to pay attention to moisture prevention.

(2) Regularly inspect the front end of the electric security fencing and promptly clean up any debris.

(3) Regularly check the pulse output voltage and energy (joules) of the electric security fencing host, and test whether the open circuit and short circuit alarms of the electric security fencing host are normal.

(4) The alloy wire at the front end of the electric security fencing should be kept moderately loose (especially in summer and winter).

(5) Timely replace aging alloy wires and accessories.
