CLASS A and CLASS B WIRING OF FIRE ALARM SYSTEM || FIRE ALARM WIRING |#firealarmtraining #firealarm

Summary

This video explains different types of wiring in system setups, particularly focusing on 'classy wiring' and 'ring wiring.' It highlights the importance of correct circuit configurations, including power and communication from both directions to ensure device functionality. The speaker elaborates on how open circuits can cause problems, and how the wiring methods, especially in large-scale projects like hospitals, ensure reliability and continuous operation. It also emphasizes the use of diodes, proper connections, and the role of the last device in the wiring loop for safety and efficiency in electrical systems.

Takeaways

• 😀 Proper wiring systems are essential in electrical panels to ensure reliable performance and safety.
• 😀 Classy wiring is a key method used for ensuring that power and communication flow from both directions in a system.
• 😀 Single open circuits can cause device failure, leading to issues such as power loss or communication breakdown.
• 😀 Classy wiring systems have a ring-type structure, allowing continuous power and communication flow even if one part fails.
• 😀 Troubles in a single open circuit can lead to serious issues, but the class wiring method minimizes such risks.
• 😀 Power and communication are provided through both directions in a classy wiring system, ensuring more robust functionality.
• 😀 The system wiring process involves careful planning, with safety and efficiency being prioritized.
• 😀 Classy wiring systems are often used in large government hospitals and other significant projects for enhanced reliability.
• 😀 Using a looped or ring wiring setup offers benefits like better monitoring, control, and continuous power to devices.
• 😀 Devices in the wiring system must be correctly connected to avoid problems like circuit breaks or short circuits.
• 😀 Different companies may use different wiring standards or materials, but the principle of ensuring safe and effective power distribution remains the same.

Q & A

What is the first type of wiring discussed in the script?

The first type of wiring discussed is 'Classy Wiring,' which is described as a ring-type wiring where power and communication flow in both directions.

What is the issue with open circuits in Classy Wiring?

Open circuits can cause trouble on the panel, as certain devices will not work if there is a break in the circuit. This can lead to a failure in the system.

How does Classy Wiring work differently from other wiring types?

Classy Wiring provides power and communication from both directions, making it more resilient. If a circuit opens anywhere, devices will continue to function due to power and communication still reaching them from the other direction.

Why is Classy Wiring important in large systems?

Classy Wiring is important in large systems like government hospitals and large projects because it ensures that devices continue to work even if there are faults like short circuits or open circuits. It maintains functionality and operation.

What happens in a system when there is an open circuit in Classy Wiring?

When there is an open circuit, the devices in the system might stop receiving power, which can lead to a breakdown in operation. However, because Classy Wiring has redundant paths for power and communication, it helps prevent complete failure.

What is the role of a return in Classy Wiring?

The return in Classy Wiring ensures that power flows back through the system to complete the circuit. This allows devices to operate properly and helps in monitoring and controlling the system.

What is the significance of the 'L1' and 'L2' connections in the system?

'L1' and 'L2' refer to different power lines that are used for safe power distribution. They ensure that power is properly supplied to all devices, and specific colors (like red) are used to mark these connections in the wiring.

What is meant by 'Offline Diode' in the wiring system?

An offline diode is used to ensure safety in the system. It helps in maintaining the correct flow of power and protecting the devices from possible faults like short circuits.

Why is the connection of power from both sides important in Classy Wiring?

Connecting power from both sides ensures that if one side fails, the other side can still provide power and communication, preventing system downtime and ensuring continuous device operation.

How does the monitoring and control work in a Classy Wiring system?

Monitoring and control in Classy Wiring are achieved because the system allows communication in both directions, enabling real-time tracking of device performance and enabling troubleshooting if needed.
