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

Description

(Parameter set numbers in brackets)
High Suppression (8):
To cover applications with permanent, optical deceptive phenomena (dry ice in
discotheques, welding), this parameter set only reacts when a temperature rise of
approx. 8 K is detected in addition to the optical signal. Due to the combination of
optical and thermal signals, it is better suited than a pure heat detector. This
parameter set is also suited for applications that can otherwise only be covered
with special detectors.
Suppression (5):
Thanks to its very robust behavior, the 'Suppression' parameter set is particularly
suitable for 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' 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 priority of the 'Robust' parameter set is to a robust response. The sensitivity is
the same as with the 'Suppression' parameter set; however, deceptive phenomena
are not explicitly analyzed and suppressed. It is thus 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):
This parameter set is only available with 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 'Balanced' parameter set reveals a balanced response behavior regarding
reaction to fires and robustness to deceptive phenomena. It reacts faster with open
fires. It reacts slower with vapor, cigarette smoke or smoldering fires.
