Smoke Detector

• Function: Smoke detectors are designed to detect the presence of smoke particles in the air. When smoke enters the detector, it triggers an alarm to alert occupants of a potential fire and give them time to evacuate or take appropriate action.
• Types: There are two main types of smoke detectors: ionization smoke detectors and photoelectric smoke detectors.
  • Ionization Smoke Detectors: These detectors contain a small amount of radioactive material that ionizes the air within the device. When smoke particles enter the detector, they disrupt the ionization process, triggering the alarm.
  • Photoelectric Smoke Detectors: These detectors use a light source and a light sensor. When smoke enters the detector, it scatters the light, causing it to be detected by the sensor and triggering the alarm.
• Power Source: Smoke detectors can be powered by batteries or be hardwired into the electrical system of a building. Battery-operated smoke detectors are typically easier to install and can be placed anywhere. Hardwired detectors require professional installation and may have backup batteries in case of a power outage.
• Interconnectivity: Some smoke detectors are designed to be interconnected, meaning that when one detector detects smoke and triggers an alarm, all interconnected detectors in the building will also sound their alarms. This provides enhanced notification throughout the premises.
