What is the primary purpose of installing smoke detectors in residential homes?

The primary purpose of installing smoke detectors in residential homes is to detect smoke and alert occupants. Smoke detectors play a crucial role in fire safety by providing early warning of potential fires, allowing residents to evacuate the premises and seek safety. Early detection can significantly reduce the risk of injury or loss of life, as well as minimize property damage by facilitating a quicker response to a fire emergency.

While other factors like compliance with insurance policies or enhancing property value may influence the decision to install smoke detectors, they are secondary to the essential function of smoke detectors: to safeguard lives by warning occupants of smoke and potential fire hazards. This is why the correct answer focuses on their primary role in fire detection and occupant safety.
