Photoelectric/Ionisation (Dual Sensor) smoke alarms are designed to
detect both the visible particles (associated with slow smouldering fires)
and invisible particles (associated with fast flaming fires). Home fires
develop in different ways and are often unpredictable. For maximum
protection against fast flaming fires and slow smouldering fires, both
ionisation and photoelectric alarms should be installed.
