                   optical smoke alarm

Optical Smoke Alarms can be used in hallways, landings and your living room. Optical smoke alarms are very effective with detecting larger particles produced by slow-burning fires such as smouldering foam-filled upholstery and overheated PVC wiring. They are also slightly less sensitive to flaming fires. Expect to pay a bit more for optical smoke alarms.


Ionisation Smoke Alarms are ideal for use in bedrooms. This is because Ionisation smoke alarms are very sensitive to small particles of smoke produced by fast flaming fires such as fires from wood, pans and paper. This also means an Ionisation Smoke Alarm will not work appropriately near a kitchen as something as small as burnt toast could set the alarm off. They are therefore marginally less sensitive to slow burning and smouldering fires, which give off larger quantities of smoke before flaming occurs. These alarms also tend to be cheaper than the optical smoke alarms.
