Air flow monitoring
An air flow sensor checks the connected pipe system for breaks and blo-
ckages.
The airflow monitoring is
temperature-compensated
and can be config-
ured
air pressure-dependent
.
After an adjustable fault delay period finishes, the fault is displayed on
the front panel and, if connected to a fire alarm system, an appropriate
signal is forwarded to the fire alarm system via a potential-free contact.
The basic signal process in the air flow sensor is shown in Fig. 2.3.

1U system is fully
automatic by pressing the “Config” and “Reset” buttons simultaneous on
the front panel. This reduces commisssionig time to a minimum.
Reset
A fault signal is reset using the reset button on the front panel of the de-
vice or by remote reset either via the connected fire alarm system or by
an external contact.
Optical
and
acoustic alarm
In the event of a main alarm in the TITANUS
RACK·SENS
®
1U system,
an internal optical and acoustic alarm is activated. The optical alarm is
provided by a red alarm lamp on the front panel. The acoustic alarm is
performed by an integrated buzzer.
