Why VESDA Smoke Detection?
With its heritage tried and
tested in the specialist fire detection industry, VESDA is now recognised as
the trusted benchmark throughout the business for all air sampling, smoke detection and fire detection purposes.
FSL recommend and install
the entire VESDA product range as well as being able to supply the entire range
and accessories to trade clients and individual customers. Our services include a full area risk assessment, system design, system installation, as well as an excellent back-up service for system maintenance and training.
In addition to all of this FSL have
also designed and now manufacture itsÃ¢â‚¬â„¢ own high grade ABS piping and fittings
to ensure the very best protection within the industry, for your assets
and your business
Traditional smoke detection
systems have the drawback of having to be strategically, and often
inconveniently (sometimes incorrectly!) located to maximise their
VESDA control boxes can be
located in easy to reach positions The associated network of FSL ABS pipe work
is structured to comprehensively sample air right throughout any given risk
areas. All of this alleviates disruption to your business and makes for high safety
and lost cost.
VESDA detection for
VESDA smoke detection is a suitable replacement for conventional smoke detection where accessibility is limited. For example, VESDA detection will be better suited to a warehouse with smoke detectors situated at high levels. Conventional smoke detectors can become faulty and access equipment will need to be deployed, this can be extremely disruptive to operation and it is also dangerous. VESDA smoke detection eliminates this issue as the aspirating pipe work will be located at high levels and the VESDA detector will be located at accessible levels. Aspirating pipe will replace the smoke detectors at high level, with holes in the aspirating pipe replacing the smoke detectors. VESDA smoke detectors have 18000 events log memory. Smoke levels can be tracked and identified against time and density. Commissioning VESDA should include measure smoke tests. There are different tests for different applications, these are measure with a set amount of smoke and readings from the VESDA detectors tell us how the system will perform in a real life situation!
VESDA detection for cold
VESDA smoke detection is
commonly used where temperatures are not suitable for other types of smoke
detection. For example, a cold room operating temperatures ranging from 20Ã¢â‚¬â„¢C to
-20Ã¢â‚¬â„¢C is an ideal environment for VESDA smoke detection. Cold temperatures will
ice up the optical chambers of conventional smoke detectors rendering the system
useless. VESDA detectors are located outside the cold environment, with aspirating pipe work
located within the risk or outside the risk with capillary smoke sampling heads
located within the risk! The cold air is then drawn to the VESDA smoke detector
and is naturally heated before it arrives at the VESDA laser chamber. The
condensation is collected at a condensate water trap and dry air arrives for
sampling by the VESDA detector. In extreme cases air dryers may be needed, but
in the most, are not required for the VESDA system!
VESDA detection for
VESDA detection is ideal for
area that have high airflow. Conventional smoke detectors struggle to activate
with volumous air passing through their chambers. VESDA detectors draw smoke
from the aspirating pipe and the holes in the pipe collectively capture the air
and draw it back to the VESDA detector. Fire Suppression Limited have conducted
test which conclusively prove that VESDA smoke detection is far more responsive
than conventional smoke detectors. Measured tests again provide reports and
samples of how the VESDA detectors will operate in a high airflow environment.
VESDA detection for Fire
VESDA detection with Fire
Suppression is a fantastic combination. With ever increasing environmental
responsibilities, it is essential that a fire suppression system should deploy unnecessarily.
VESDA smoke detection use in conjunction with conventional smoke detection is a
perfect match. Preferably VESDA detection samples the air across the return
plenums of the air conditioning systems which provide primary smoke detection!
An alert alarm can be raised and human intervention can prevent the gas from
discharging! VESDA can also be used as a double knock system,
which provides the most suitable fire detection model for any automatic fire

With the recommendations of
the BS5839 that stipulates that any ceiling void over 800mm in depth must be
treated as the area below. With todayÃ¢â‚¬â„¢s modern architecture, many ceiling are
solid ceiling with little access. VESDA smoke detection is ideal for this, as
the aspirating pipe work will replace the conventional smoke detection, with
the VESDA smoke detector in an accessible location.
VESDA smoke detection in
VESDA smoke detection for
lift shafts enhanced that smoke detection within what is a high sensitive area.
It also makes maintenance safe as the engineer will not need to get into the
lift shaft for maintenance purposes.
