Photoelectric smoke detectors use a light source (typically an infrared LED) and a photosensitive sensor arranged in a light-tight chamber. When smoke enters the chamber, it scatters the light beam, directing it toward the sensor and triggering the alarm. This method offers:
More effective detection for smoldering fires which produce large visible smoke particles
30-50% fewer nuisance alarms compared to ionization sensors
Better performance in residential settings with cooking activities
More stable calibration over time with less sensitivity drift
Environmentally friendly – no radioactive material (unlike ionization detectors)
Wanlin's optical smoke sensors are factory calibrated for consistent performance across temperature ranges from -10°C to +55°C and humidity up to 95%. We offer both standard sensitivity (1.5-2.0%/ft obscuration) and high-sensitivity versions (0.5-1.0%/ft) for different market needs.
