Optical Smoke Alarms
Optical smoke alarms, also called photoelectric smoke alarms, 'see' smoke. They have a quick response to visibly smouldering fires (e.g. from foam filled furniture & overheated PVC wiring). They are also particularly good in areas where you can otherwise expect false alarms (e.g. near kitchens). We recommend the use of optical smoke detectors in living rooms, bedrooms and hallways.
