Optical Smoke Detectors/Alarms
Optical Smoke Detectors are also known as Photoelectric Detectors and more effective at detecting larger smoke particles produced by slow-burning fires.
Such as smoldering foam-filled upholstery and overheating PVC wiring.
They are marginally less sensitive to flaming FIRES.
