Smoke Detector Alarm
This smoke detector alarm is generated when smoke is detected in the unit or air stream. When the smoke detector alarm
is generated, “ ALARM ” will be displayed next to “ Smoke Det. Status ” on the Alarms screen.
This alarm is generated via the opening of the normal closed smoke detector circuit and will trigger an emergency shutdown
of the unit.
When the smoke detector circuit is closed, the alarm will automatically reset.
