Optical sensors are more responsive to smouldering fires producing large particle smoke typical of fires involving furniture and bedding. They are more immune to invisible smoke produced by 'burning the toast' and similar cooking fumes. This makes them ideal for siting in hallways close to kitchens where false alarms from ionisation alarms may be a particular problem. It is recommended the use of optical detectors in circulation spaces of a dwelling, such as hallways and landings. Optical detectors are prone to false alarm if exposed to steam and should not be located too close to poorly ventilated bathrooms or shower rooms.
