The NX-492N-I is a wireless photo-electric smoke sensor with a built-in sensitivity meter monitoring continuous its own operational status and provides a visual trouble condition if it drifts out of the sensitivity range or fails internal diagnostics. The alarm sensitivity level can be determined at the alarm without a meter. Built-in drift compensation, usually only available in analog systems, allows the alarm to adjust automatically its sensitivity over time as it becomes dirty. This feature increases the time between cleanings and reduces false alarms.

Once a day and immediately upon the first power up, the alarm performs a full diagnostic test that includes a dynamic test of the sensing chamber and internal electronics.
