What is the purpose of a smoke detector breaker and how does it function in a home's fire safety system?

A smoke detector breaker is a device that controls the power supply to smoke detectors in a home. Its purpose is to ensure that the smoke detectors are functioning properly and can alert residents in case of a fire. The breaker is designed to cut off power to the smoke detectors if there is a malfunction or if the detectors detect smoke, triggering the alarm system and helping to keep residents safe.
