Optical Smoke Alarms (12 results)

Optical Smoke Alarms are more expensive but more effective at detecting the larger particles of smoke that are typically produced by slow burning fires. For example, if a sofa is smouldering from a cigarette burn then an optical smoke alarm will be better. These alarms are also less likely to go off when toast is burned so they can be placed nearer (but not in) kitchens.
