toring window can be adapted to the surrounding conditions. The dynamic
air flow sensors are only activated when the air flow threshold is set to low.
Following figure shows the signal curve of the air flow sensor.
Figure 5: Signal curve of air flow sensor during fault
A fault in the detector module or air flow activates a fault signal which is dis-
played on the TITANUS
®
display. The fault display can be set to latched
(standard) or non-latched mode.
An indication of faults and certain device states is effected through 5 differ-
ent flash codes of an LED on the (electronic circuit board) of the detector
module. This allows to quickly distinguishing between faults caused by a de-
fective detector module, a blocked or fractured pipe system.
A fault signal is reset via a connected central fire panel. If it is required to re-
set alarm and fault signals together with the detection line (when operating
TITANUS
®
connected to a CFDU), an optional reset board can be installed.
It automatically resets the TITANUS
®
alarm and fault signals in the event of a
temporary interruption in the line voltage.
The reset board can only be used if the quiescent current of the line is be-
tween 5 mA and 50mA. The line must be without current during resetting.
Each TITANUS
®
is equipped with a voltage-free change-over contact for the
three existing alarm thresholds and the collective fault. Thus, the air sam-
pling smoke detection system can be connected to collective and address-
able (Via addressable modules of the relevant central fire panel) detection
lines on any central fire panel.
