How do fire alarms work?

    Optical fire alarms – a laser inside the alarm is shone over a receptor, which when blocked by smoke causes an alarm to sound. Optical alarms are good for detecting slower burning fires which give off larger smoke particles.
    Ionisation alarms – two electronically charged plates and a small amount of radiation ionise the air inside this type of alarm system; smoke from a fire neutralises this air and sets off the alarm. Ionisation fire alarms are best at detecting small smoke particles which are typically given off by high flaming fires.
    Combined alarms – contain both optical and ionising systems for the best protection.
