What is the difference between Photoelectric and Ionisation and Photoelectric smoke alarms?
Ionisation Smoke Alarms are generally more effective at detecting flaming fires, which consume combustibles quickly and spread rapidly. Sources of these fires include paper burning in a wastebasket, or grease firs on a stove. Photoelectric Smoke Alarms are generally more effective at detecting smouldering fires, which smoulder for hours before bursting into flame. Sources of the fires include cigarette smouldering in couches or bedding. For maximum protection, install both types of smoke alarms on every level of your home.
