Neural fire detector FDOOT241-x / -Ax (sensor mode 0)

Description
Parameter sets:
High Suppression (8)
The parameter set only reacts when a temperature increase of approx. 8 K is
detected in addition to the optical signal. Due to the combination of optical and
thermal signals, it has better properties than a pure heat detector. This parameter
set is also suited for applications that can otherwise only be covered with special
detectors. E.g., applications with permanent, optical deceptive phenomena (dry ice
in discotheques, welding).
Suppression (5)
The parameter set displays very robust behavior in rooms where deceptive
phenomena such as cigarette smoke or exhaust fumes can be expected. It reacts
in a very robust way to the deceptive phenomenon vapor.
High Compensation (7)
This parameter set reacts in the same way as the 'Robust (2)' parameter set,
however, the compensation range is twice as large. This parameter set is thus
especially suited for rooms in which a lot of dust and other deposits can be
expected during longer periods.
Robust (2)
The parameter set is intended for robust response. The sensitivity is the same as
with the 'Suppression (5)' parameter set; however, deceptive phenomena are not
explicitly analyzed and suppressed. It is particularly suited to application in rooms
where deceptive phenomena such as cigarette smoke or dust can be expected.
The 'Robust (2)' parameter set is suitable for higher rooms in comparison to the
'Suppression (5)' parameter set.
Insensitive (0)
The parameter set is only available for the FDOOT241-9 (ES <13) in collective
operation. Regarding visible aerosols the priority is on robust response. The
response behavior regarding open fires is sensitive and fast.
Balanced (4)
The parameter set displays a balanced response behavior in its response to fires
and robustness to deceptive phenomena. It reacts faster with open fires. It reacts
slower with vapor, cigarette smoke or smoldering fires.
Sensitive (0)
The parameter set is only available for the FDOOT241-8 in MS8 operation. It has
been specially developed for the migration of ionization detectors to MS8 control
panels.
Regarding sensitivity and response time, the parameter set reacts in a similar way
to an MS8 ionization detector. The difference in the response behavior of an optical
detector and an ionization detector is taken into account. When the detector is
migrated to an FDnet detector line, the parameter setting should be changed to
'Fast Response (6)'.
