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.

Check the system following installation using the DIAG Diagnostic Software.
The device must be operated for at least 30 min prior to the airflow being initialized to
bring it up to operating temperature.
To initialize the connected pipe system, press the S2 flow-init button (see Figure 5,
Page 5) on the detector module concerned until the green operating LED on the unit
starts to flash. Initialization is complete after approx. 10 seconds. Following successful
initialization, the operating LED lights up permanently.
No further modifications may be made to the pipe system during or after initialization.
The unit's fan voltage must also remain unchanged following initialization. Otherwise, the
initialization procedure must be repeated.
By means of an LED on the detector module
By means of one or two LED(s) on the unit motherboard (one LED per detector module).
Airflow initialization active (flow-init)
Airflow too small (obstruction)
Airflow too large (pipe breakage)
