The XP95 Ionisation Smoke Detector uses a low activity radioactive foil to detect fires by irradiating the air in the smoke chambers causing a current flow. If smoke enters the chamber, the current flow is reduced leading to an alarm.

• Responds well to fast-burning, flaming fires
• Designed to operate in a variety of environments
• Minimal effects from the temperature, humidity, atmospheric pressure
• Well protected against electromagnetic interference over a wide frequency range
