Service LED indicators and buttons
Flow OK
As soon as the selftest for normal operation has been completed successfully, the 'Flow OK'
LED starts to flash.
Smoke OK
As soon as the selftest for normal operation has been completed successfully, the
'Smoke OK' LED starts to flash.
Alarm
In the event of a smoke alarm, the 'Alarm' LED starts to flash.
Normalization of the airflow
To determine the nominal airflow of the detector, perform this function during commissioning.
The nominal value established during normalization of the airflow forms the setpoint value for
monitoring the airflow during normal operation.
To perform this function, use a thin object (such as a paper clip or a watchmaker's
screwdriver) to press the button in the opening.
Once you have finished with this function, press the button in the opening again.
The smoke detector uses standard values for monitoring during normalization.
Normalization of the smoke density
To determine the nominal air quality in relation to the smoke density, perform this function
during commissioning. The nominal value established during normalization forms the
setpoint value for monitoring the smoke density during normal operation.
To perform this function, use a thin object (such as a paper clip or a watchmaker's
screwdriver) to press the button in the opening.
Once you have finished with this function, press the button in the opening again.
The smoke detector uses standard values for monitoring during normalization.
The detector provides information about the current normalization process via
FDnet/C-NET (no distinction is made between smoke and airflow).
