Active vs. Passive Detection
VESDA: ActiveDetection Non reliant on air currentsfor smoke delivery
Functions effectively in wide range of environments
from high airflow to still air
Passivespot and beam type
detectors rely on thermal lift
to deliver smoke to detection
chamber.

Application Drivers - Early Warning
VESDA provides reliable detection during the incipient
stage of a fire
TIME to investigate
Maintain business continuity
Avoid smoke contamination
Avoid unnecessary suppression release

What Does VESDA Try to Avoid?
Detects in the smoldering
stage before visible smoke
Prevents damage,
downtime, pre-mature
suppression
Gives the earliest possible
warning in pre-combustion
conditions

VESDA ECO Gas Detector
-
8/10/2019 Xtralis Training 1
57/97
VESDA ECO Positioning
VESDA ECO adds gas detection capability to existing or
new installations of VESDA smoke detection systems.
VESDA ECO can detect a range of flammable, toxic and
oxygen gas hazards.
VESDA ECO can provide a greater area of coverage than
fixed point gas detection systems.
VESDA ECO is for indoor non Hazardous classified areas
only.
VESDA ECO is not intended to be a stand alone gas
detection system.
-
8/10/2019 Xtralis Training 1
58/97
A Cautionary Note
To ensure correct application of VESDA ECO, only fully
trained and accredited distributors / installers will be
permitted to sell VSDA ECO
VESDA ECO is for use exclusively with compatible
Xtralis manufactured ASD.
VESDA ECO has been third-party validated, ensuringXtralis ASD smoke performance is not compromised.
VESDA ECO is not approved or warranted for use on
other (non Xtralis) ASD products.
No other third party gas detector is approved for use with
Xtralis ASD and would void the Xtralis ASD warranty.

Features (Detectable Gases)
VESDA ECO detectors have a sensor cartridge containing 1 or 2 gas sensors.
VESDA ECO uses industry proven electrochemical & catalytic sensors.
Additional gases will be added to the range. All new requests welcomed.

gy
dust particles are counted as they pass through the
detector chamber.
You can enter a predetermine time stamp i.e.. 730
days (2 years) and at the end of that time a filterwarning is given to re-visit the detector to determine if
a new filter needs to be inserted.
Replace filters every 24 months, or as needed for
challenging environments. When the filter is removed from the VLP, the aspirator
shuts off, the buzzer sounds (if enabled) and an
urgent fault is raised.
