What is the characteristic feature of the fire detection system that uses two wires embedded in a ceramic core?

• A. Kidde System
• B. Thermocouple System
• C. Fenwal System
• D. Lindberg System

Answer: (A)

The characteristic feature of the fire detection system that uses two wires embedded in a ceramic core is primarily associated with the Kidde System. This system employs a type of sensor that utilizes the principles of conductivity based on heat. The two wires create a circuit that becomes conductive at certain temperatures, indicating the presence of a heat source indicative of a fire. Such systems are designed for high reliability and quick response to temperature changes, which is essential for effective fire detection in powerplants. The choice of a ceramic core serves to enhance the sensitivity and durability of the sensors, making them suitable for harsh environments often found in power generation facilities.
