Notice!
When the fire panel is in revision operation, the LOGIC×SENS is temporarily deactivated. This
allows the detector module to be checked quickly and directly.
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.
Fire source identification
With the device variants FAS-420-TM-R and FAS-420-TM-RVB, it is possible to assign each of
the five monitored rooms a designation. To do this, click on the corresponding room and enter
the designation for this room in the "Label" field. The designation can be a maximum of 31
characters. In the event of a fire, this designation is displayed on the fire panel's operating and
display unit, making it possible for the fire source to be clearly pinpointed.

Fire source identification
Notice!
The term "ROOM×IDENT" is used in the FAS‑ASD‑DIAG Diagnostic Software for identifying the
fire source.
Fire source identification is activated/deactivated using the FAS‑ASD‑DIAG Diagnostic
Software via the "Settings" screen. The "ROOM×IDENT" function is deactivated as standard.
Main alarm following Fire source identification
For certain applications, it is practical to perform the alarm signaling once the fire location has
been identified. To do this, the Fire alarm after ROOM·IDENT must be activated. It is important
to remember that when this function is activated, the ROOM·IDENT function must also be
activated; otherwise, the fire location cannot be identified.
The Main alarm after ROOM IDENT function is deactivated as standard.
