How we test
Overall score is based on smouldering and flaming fire sensitivity.
“Good” or “OK” meant the alarm sounded quickly enough to alert you to danger.
“Poor” meant the alarm took significantly longer to sound.
“Extreme” sensitivity meant the alarm sounded so quickly they are more likely to issue false alarms.
Ease of use includes instructions and ease of installation.
Noise is measured in a quiet room 3m from the alarm.
