TECHNICAL MANUAL
2.1.1 Function
The aspiration unit in the basic device draws air samples from the area to be
monitored via a pipe system with defined air sampling points. The air samples
are then passed to the sensitive detector module (refer to 2.1)
Detector Module
Dependent on the response sensitivity of the used detector module (up to
0.5%/m, 0.1
%/m or 0.015 %/m light obscuration) TITANUS
PRO·SENS
®
activates the alarm when the corresponding light obscuration is achieved. Four
different alarm thresholds can be set. The alarm is indicated at the device via
the alarm LED and can be transmitted to a connected fire detection control and
indicating equipment (F.D.C.I.E.).
Different delay periods can be set for the alarm thresholds and the fault display
and fault transmission (refer to chapter 5.3).
Alarm indications are stored and have to be reset after eliminating their cause.
For TITANUS
PRO·SENS
®
2 two detector modules allow to monitor two areas
the way described above. If one area is to be monitored, a two-detector
dependency and additionally through the choice of different response
sensitivities an action alarm can be realized.

TITANUS
PRO·SENS

incorporates an intelligent signal processing system with
LOGIC
·SENS
,
which can be activated and deactivated with a switch at the
detector module. This fades out interferences and contributes to a safe
operation without false alarms.
Monitoring the Detector
Module
Each detector module is checked for soiling, signal faults and detaching. In the
event of the detector module becoming soiled a drift is affected. A fault is
indicated by the fault-LED at TITANUS
PRO·SENS
®
and can be transmitted to a
fire detection control and indicating equipment (F.D.C.I.E.) via a fault contact. In
order to avoid false alarms faults are processed with a delay.
Air Flow Monitoring
An air flow sensor checks the connected pipe system for fracture and blockage.
Dependent on the design of the pipe system (refer to chapter 4 "Pipe Design“––
the air flow sensor can detect at least a blockage of 50% of the air sampling
points up to the complete blockage and a fracture of the pipe system causing a
loss of 50 % of the air sampling points. If the ventilator fails, the air flow in the
pipe system is interrupted causing a blockage which is indicated. The air flow
monitoring is temperature compensated and can be set to an air pressure
independent mode.
