What is the purpose of overcurrent protection in fire alarm systems?

Overcurrent protection in fire alarm systems serves a crucial role in preventing damage to equipment. Fire alarm systems consist of various electronic components, and when excessive current flows through these components, it can lead to overheating, component failure, or even fire hazards. Overcurrent protection devices, such as circuit breakers or fuses, are designed to interrupt the electrical circuit when the current exceeds a predetermined threshold. This ensures that the sensitive components of the fire alarm system are safeguarded, maintaining the reliability and functionality of the system.

The other options do not accurately reflect the primary purpose of overcurrent protection. While enhancing efficiency, regulating power supply, or improving signal transmission may be important in different contexts, they do not capture the critical protective function that overcurrent protection provides in ensuring the safety and operational integrity of fire alarm systems.
