Detector
Head
If the detector head detects smoke aerosols in the air sample the current
smoke level is indicated by TITANUS
®
through the level display. The
three alarm levels alert, action and fire alarm are indicated by LED’s and
can be passed to the central fire panel via potential-free contacts. Differ-
ent delay periods can be set for the alarm levels. In the event of the de-
tector head becoming soiled a drift is effected. The drift complies with the
requirements of the valid European standard.
The alert alarm can be set to a latched (standard) or non-latched mode.
In contrast to this the action alarm and fire alarm are always set to the
latched mode. The alarm indications are to be reset after the cause of the
fault has been cleared.
Monitoring of the
Detector
Head
The detector head is checked for soiling, signal faults, detaching and volt-
age. A fault is indicated through the fault-LED of TITANUS
®
and can be
passed to the central fire panel via a fault contact.
Air Flow Monitoring
An air flow sensor checks the connected pipe system for fracture and
blockage.
Dependent on the pipe system design (refer to chapter 4 "Project Plan-
ning") the air flow sensor detects a blockage from 15% of the air sam-
pling points up to the complete blockage and a fracture of the pipe
system at the fares point. If the ventilator fails the air flow fault in the pipe
system is interrupted and a blockage is indicated. The air flow monitoring
is
temperature compensated
and can be set to an
air pressure inde-
pendent mode
.
After a delay period which can be programmed by switches the fault is
indicated at the air sampling smoke detection system and if required, the
fault signal is passed to the central fire panel via a fault contact. The
thresholds of the monitoring window can be adapted to the ambient con-
ditions (refer to chapter 4 “Project Planning“).
