How does a Photoelectric Smoke Detector Work?

Russ Porteous, the CEO of Firewise, explains the workings and advantages of photoelectric smoke detectors in this video. These detectors can identify early-stage, smouldering fires by detecting airborne smoke particles. Their components include a durable housing, an insect-resistant shield, an optical labyrinth, an internal chamber with a light transmitter and sensor, and signal processing circuitry. They're effective, reliable, require minimal maintenance in line with Australian Standard AS1851, but need regular testing. Though the detectors typically last around ten years, their lifespan may be affected by contamination, aggressive environments, and ageing. Regular inspections beyond standard requirements can help avoid false alarms due to contamination.
