Spoken about above you can find three kinds of alarm, each having its own uses.
Optical Alarm: This sort of smoke alarm usually uses an infrared beam between two points, the alarm being triggered should the beam be disturbed. In similarly like a criminal might trip a security alarm when breaking into a financial institution vault or museum within the movies, if the beam is broken, the alarm will go off. It detects larger smoke particles best.
Ionisation Alarm: These alarms use 2 small plates (one charged positively, one negatively) with an alpha particle source to create a constant current running over the gap involving the plates. When smoke enters the chamber it interferes with this procedure, interrupting the charge. When the charge drops, the alarm is triggered. These alarms would be best at detecting smaller smoke particles.
Heat Alarms: A heat alarm will trigger in the event the 70 degrees reaches a particular level. They cannot detect smoke, and aren't to use alternatively to get a smoke alarm, but ought to be utilized in assisting these alarms for greater fire detection.
