1.4. LED Operation

The two−color LED of the detector indicates the operation and alarm statuses.
During the whole life cycle, the sensors are self−monitored and the sensitivity is self−
adjusted according to the programmed threshold. In case the detector is heavily conta-
minated, a message is sent to the fire panel.
In case of an alarm, the LED flashes red. The detector is set back to standby if the
alarm is reset via the fire panel and if the cause of the alarm is gone.
