Smoke Detector – Summary Description:
A smoke detector is a safety device designed to sense the presence of smoke, typically as an early warning of fire. It uses either photoelectric or ionization sensing technology—or a combination of both—to detect smoke particles in the air. When triggered, the device emits a loud alarm to alert occupants, giving them time to evacuate or address the danger.
• Key Features:
• Detects smoke from smoldering or flaming fires
• Battery-powered or hardwired with battery backup
