There are two main types of smoke alarm for home use: ionisation and photoelectric alarms.
Ionisation alarms contain a small amount of radioactive material. Photoelectric alarms are recommended by most fire authorities. Studies have shown that photoelectric alarms typically respond to smoky fires within about three to five minutes. Ionisation alarms can take much longer – up to 20 minutes or more – by which time escape can be much more difficult.
