Parameter Settings via RPS
The parameters for each detector module are specified in the relevant "Sensor" dialog window
via drop-down fields.
–
Enter the used detector module.
–
Select all other parameters (see tables).
The default settings in RPS are in bold in each table.

Notice!
When the fire panel is in revision mode, the LOGIC·SENS is temporarily deactivated, allowing
the detector modules to be checked quickly and directly.
The sensitivity value is based on measurements with standard test fires (old value in
brackets).The activation threshold for the airflow malfunction is set to 20% volume flow
change by default. Higher values are not permitted within EN 54‑20 or ISO 7240-20.

For commissioning and initialization with S2 flow init button, refer to graphic
1.
Check the system using the FAS‑ASD‑DIAG Diagnostic Software.
Notice!
The Aspiration smoke detector must be operated for
at least 30 min prior
to the airflow being
initialized to bring it up to operating temperature.
