Takeaways
- 🔍 Conduct thorough checks for open circuits, short circuits, and ground leakage before operating the ML120 2x Smart Addressed Fire Alarm system.
- 🛠 Ensure that the ring circuit wire used in the system is not longer than 1200 meters for a 0.8 mm² cross-sectional area, and not longer than 1500 meters for a 1.5 mm² cross-sectional area.
- 🔌 Check for continuity and proper connections in the ring circuit wiring, including the screen wire, to avoid open circuit issues.
- 🔍 Perform line checks to identify any open circuits by tracing the project and narrowing down the area with the fault.
- 🔌 Ensure that there are no missing connections in the ring circuit wiring, as this indicates an open circuit that needs to be resolved.
- 🔍 When checking for short circuits, verify that there is no direct connection between the positive and negative wires, the screen wire, and the earth wire in the circuit.
- 🛠 If a short circuit is detected, connections need to be made to the control center to resolve the issue.
- 🔌 In ground leakage checks, ensure that the positive and negative wires of the circuit do not touch water or ground through the ceiling, walls, or similar points.
- 🔧 Correct any identified points where the wires are touching water or ground to prevent ground leakage.
- 🔋 Measure the external voltage of the control center's 24V DC series with a measuring instrument, which should be within the range of 12.30 to 13.50 volts.
- ⚠️ If the measured external voltage deviates more than 20 millionths from the specified range, it indicates a ground fault that needs to be addressed.
Q & A
What is the main topic of the video script?
-The video script is about the installation and troubleshooting of an ML120 2x smart addressable fire alarm system.
What are the initial checks required before operating the fire alarm system?
-Before operating the system, it is necessary to check for open circuits, short circuits, and ground leakage to ensure there are no issues.
What is the recommended cross-sectional area for the circuit wire used in the system?
-The recommended cross-sectional area for the circuit wire is 0.8 millimeters for a maximum length of 1200 meters, and 1.5 millimeters for a maximum length of 100 meters.
What should be checked during the circuit installation?
-During circuit installation, it is important to check for any missing connections, reversals of positive to negative and vice versa, and the presence of a screen cable in the circuit.
What does it mean if there is a missing connection in the circuit?
-A missing connection in the circuit indicates a wire breakage, which is a problem that needs to be resolved.
How is a wire breakage or short circuit identified in the project?
-Wire breakages or short circuits are identified by following the project and using a narrowing method to locate the faulty cable or connection point.
What checks should be performed during a short circuit inspection?
-During a short circuit inspection, one should check for any shorts between the positive and negative, between the screen and the positive, and between the screen cable and the ground.
What is the acceptable voltage range for the external voltage measurement?
-The acceptable external voltage range is between 12.30 to 13.50 volts, with a tolerance of plus or minus 20 millionths.
What does it indicate if the measured external voltage deviates more than the specified tolerance?
-If the measured external voltage deviates more than the specified tolerance, it indicates a ground fault that needs to be corrected.
How is a ground leakage issue identified and resolved?
-A ground leakage issue is identified by following the project and using a narrowing method to locate the cable or connection point with leakage. The identified points must be corrected.
What is the final call to action for viewers in the video script?
-The final call to action is to subscribe to the channel for more information.

Highlights
Before operating the system, it is necessary to check for open circuits, short circuits, and ground leakage and resolve any issues.
The loop wire used in the system should not exceed 1200 meters in length with a cross-sectional area of 0.8 mm².
For loop wires with a cross-sectional area of 1.5 mm², the maximum length should not exceed 1000 meters.
When performing wire break checks, it is important to inspect the plus and minus connections in the loop wiring and the screen wire connection.
If any of the connections are missing, it indicates a wire break that needs to be addressed.
Short circuit checks involve verifying the connections between plus and minus, plus and screen, and screen and ground in the loop wiring.
If a short circuit is detected, connections to the control center must be re-established.
Ground leakage checks require inspecting whether the plus and minus wires in the loop wiring are in contact with water or ground.
Any points of contact must be corrected if ground leakage is detected.
During ground leakage checks, the control center should provide energy, and the control panel's 24V DC series should be measured.
The external voltage value measured should be between 12.30 and 13.50 volts with a tolerance of ±20 millivolts.
If the measured value deviates more than ±20 millivolts, it indicates a ground fault that needs to be corrected.
To resolve ground leakage issues, the project should be followed up, and the area should be narrowed down to identify the cable or connection point causing the leakage.
The video provides a step-by-step guide for troubleshooting common issues in the installation of the ML120 2x smart fire alarm system.
The importance of proper wiring and connection checks is emphasized to ensure the system's reliability.
The video covers the technical specifications for the loop wire, including length and cross-sectional area requirements.
Troubleshooting steps include checking for wire breaks, short circuits, and ground leakage to maintain system integrity.
The video instructs on how to measure the external voltage to diagnose potential issues with the system.
Corrective actions are detailed for resolving detected issues, such as wire breaks and ground faults.
The instructional video aims to assist technicians in the proper installation and maintenance of the fire alarm system.
