4.2.2 Parameter sets: Sensor mode 0 'Neural fire detector'
4.2.2.1 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 (5)' parameter set is
particularly suitable for rooms where deceptive phenomena such as vapor, very
dense cigarette smoke or exhaust fumes can be expected. It reacts in a very
robust way to the deceptive phenomenon vapor.
Suppression CO (12):
Thanks to its very robust behavior, this parameter set is particularly suited for
rooms where deceptive phenomena such as vapor, cigarette smoke or exhaust
fumes can be expected. It reacts in a very robust way to the deceptive
phenomenon vapor. In the event of smoldering fires or fires in rooms where
cleaning products are stored, the parameter set reacts quicker than the
'Suppression (5)' parameter set as it takes the CO concentration into account.
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 priority of the 'Robust (2)' parameter set is on 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 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.
Balanced (4):
The 'Balanced (4)' 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.
