Ionisation type sensors are particularly sensitive to the almost invisible smoke produced by fast flaming fires. This makes them more liable to false alarm due to cooking fumes if sited in a hallway close to a kitchen. Ionisation detectors are recommended in living rooms and dining rooms where they are less vulnerable to false alarm caused by dense tobacco smoke, excessive dust and insect ingress.
