Technical Description
06/13 25
Each detector module is checked for soiling, signal faults and detachment. A
fault is shown on the fault indicator of TITANUS
®
and can be transmitted to
the CFDU via a fault contact. Faults caused by short-lived surround fluctua-
tions can be masked out with a time-delayed setting.
An air flow sensor checks the connected pipe system for fractures and
blockages.
The air flow sensor can recognise a blockage of the air sampling points of at
least 50% to total blockage and any pipe fracture, which would result in a
50% loss of air sampling points. Depending on the design of the pipe sys-
tem, blockages of individual air sampling points can also be recognised. The
air flow monitoring system is temperature-compensated and can be set to be
air pressure-dependent.
After a delay period, which can be programmed by switches, the fault is indi-
cated on the air sampling smoke detection system and, if required, the fault
signal is passed to the CDFU via a fault contact. The thresholds of the moni-
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.

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.
