    How we test

    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.

    See "About our test" for more information.

    Noise is measured in a quiet room 3m from the alarm.
