Optical smoke alarms, also known as photoelectric detectors, are less prone to false alarms than ionisation models and are slightly quicker at detecting slow smouldering fires that tend to produce a lot of smoke.

What’s the difference between ionisation and optical smoke alarms?

Types of smoke alarms Ionisation alarms are very sensitive to cooking vapours and if placed near a cooker or toaster are likely to give frequent false alarms. Optical alarms detect larger particles of smoke, the kind that are produced by a slow smouldering fire before it bursts into flames.
