Firex Ionization Smoke Alarms
The Firex ionization smoke alarms are ideal for fast moving, flaming fires. Ionization-type smoke alarms work because there is a small amount of radioactive material between two electronically charged plates which causes current to flow between the plates. When smoke enters the chamber, it disrupts the flow of ions, thus reducing the flow of current and activating the alarm.
