Any smoke detected in the laser detection chamber is signaled to the main processor card. If the
presence of detected smoke is higher than the set thresholds it is reported as a Pre-Alarm or an
Alarm depending upon the alarm thresholds. The second stage filter further filters the air to
produce ultra clean air. The ultra clean air is used to clean the optical surfaces in the laser
detection chamber.
