Which of the following describes the components of a kidde continuous loop fire detection system?

The Kidde continuous loop fire detection system utilizes an Inconel tube with a ceramic core as its primary components. Inconel is a highly durable metal that withstands extreme temperatures and corrosive environments, making it ideal for aviation applications where reliability is critical. The ceramic core within the tube serves as a thermosensitive element, which expands and contracts with temperature changes.

When a fire occurs, the heat causes the ceramic material to expand, resulting in a change of the electrical impedance within the loop. This change triggers the fire detection system, alerting the crew to a potential fire hazard. The design of the Inconel tube ensures that the system can function effectively in high-stress environments encountered in aircraft operations.

Other options, while they may describe various types of materials, do not correctly represent the components and functioning of the Kidde continuous loop fire detection system. For example, a stainless steel tube does not have the same thermal properties as Inconel, and the use of ceramics provides the necessary sensitivity to heat that is vital for effective fire detection.
