It includes a lightweight supply, that is positioned indirectly to The sunshine sensitive electric sensor. Ordinarily, light from the light source shoots straight across and misses the sensor. When smoke enters the chamber, it scatters The sunshine, which then hits the sensor and triggers the alarm.
