Key Features
Each ECO detector contains a plug in gas sensor cartridge which houses up to two
gas sensors. This can provide significant cost savings over conventional point
systems which require two or more detectors. At the end of the serviceable life of
the gas sensors, a pre-calibrated plug-in replacement sensor cartridge can be
supplied and fitted.
Four colour indicators located on the cover show the power, alarm and fault
conditions.
Four fully configurable on board relays are provided to indicate alarm and fault
conditions and can be used to activate external remote indicators and beacons.
Two 4-20mA current source outputs are available, as supplied these are configured
to each of the gas sensors and scaled to match the measurement range.
An RS485 Modbus RTU interface is provided by which a number of detectors can
be interfaced to the Xtralis VSM4 monitoring package or other system.
Event logs are stored via the removable microSD card and retrieved to a host PC
running the Xtralis VSC software either directly using an SD Card connection or via
the USB interface.
VSC gives the user the facility to read current and historical events, change the
detector configuration settings and conduct detailed fault diagnostics.
An integrated gassing port allows simple application of zero and calibration test gas
for set up and routine maintenance.

Any installation of an ECO gas detector must comply with local
safety regulations and to the fire safety regulations
when being fitted as
part of a fire detection network.
Before commencing the ins
tallation process the system designer and installer must
first carefully consider where in the pipe network the ECO device is to be located.
The initial stage of the design process requires completion and submission of the
VESDA ECO application form. Thi
s is available from, and should be returned
your local Xtralis Field Applications Engineer or qualified distributor / installer.
To be effective the ECO device must be installed with a properly designed and laid
out aspiration pipe network. If the unit is to be
fitted to an existing pipe network, the
designer and installer of the system must ensure that the addition of ECO gas
detectors does not invalidate the certification of the installed system.
There are three possible mounting configurations for the
ECO detector
Figure 2 below.
Figure 2 -
Alternative gas detection configurations
•Localized Point Mounting -
mounting a detector at a specific location in
the pipe network permits local
ized monitoring to give earlier detection of
gas levels in a higher risk area, reducing both the transport time and
possibly the dilution of the sample.
•Inlet Mounted -
mounting a detector on one of the inlets of the aspirator
permits selective monitoring
of that branch of the pipe network.
•Exhaust Mounted - mounting a detector o
n the exhaust
permits the entire pipe network
to be monitored by a single detector.

6 Detector Location 17898_05
In choosing the location for the ECO detector(s) the installer must consider the
following issues
•Aspirator Proximity – When fitted to the inlet pipe of the VESDA detector,
the ECO should be located more than 0.5 m (20 inches) from the VESDA
detector inlet.
•Flow Restriction – When mounted locally to the gas source, i.e. some
distance away from the aspirating device, ensure that there will be
adequate sample flow through the ECO to permit adequate operation.
•Gas Density – The gas to be sampled may be significantly lighter, e.g.
Hydrogen, or heavier, e.g. Hydrogen Sulphide, than air and as such will
gather in higher concentrations in high/low levels within the detection
space, especially areas such as ceiling voids, inspection pits and
stairwells. NB. Training materials are available from Xtralis to provide a
full understanding of the implications of gas characteristics when designing
the installation.
•Cabling – The installer must consider the cabling requirements of the
ECO within the scope of the overall site installation, refer to the Electrical
installation section on page 11.
•Access – The installer must ensure that there is sufficient access to the
ECO detector, i.e. that the indicators can be seen, the cover can be
removed for service and maintenance activities and that there is sufficient
access to the gas test port if it is to be used.
•Mounting – Finding a suitably long straight section of pipe with sufficient
access to fit the body of the detector, without interfering with other
equipment in the location.
•Environment – That the ambient local environment where the unit is to be
placed does not exceed its specification, which must include the
consideration of local sources of heat (e.g. radiators), cold (e.g. freezers),
humidity and EMI (e.g. radio transmitters, electrical installations switching
high currents and/or voltages etc.).
Location of the ECO detector should be pre-planned to take account of all of the
above factors. In existing systems it may be necessary to run additional pipe work
for the benefit of gas detection.
For further information on designing air sampling pipe networks please refer to the
Pipe Network Design and Installation Manuals or contact your local Xtralis Field
Applications Engineer (FAE).

Mechanical Installation
Do not install your ECO detector if there are any signs of shipping
damage.
Inform your distributor if there is any visible damage.
Check the Model of
ECO Detector is correct as per design specifications for the
site. Refer to the Model number located on the main product
label
the gas types and ranges are of the correct specification.
Follow the steps below to fix the Detector to the pipe work
•
Before fitting the ECO unit to the pipe work, ensure that any glue used in
fixing the pipes has been given sufficient time to cure such that it any
vapours from the glue will not affect the gas detection.
•At the preferred location within the pipe
work, as determined by reference
to the previous section of this document, remove
a straight
the pipe. The exact length of pipe to be removed
will depend on the
tolerances of the pipe-
work being used, but as a guide the lengths are
approximately
o60 mm when installing in a 25mm OD pipe
o4 inches (100 mm) when installing in a ¾” BPS
pipe
It is suggested that the pipe is cut to permit subsequent adjustment if
required, to maintain a good airtight fit.
•Ensure that the cuts on the pipe are perpendi
cular to the pipe and that
there are no burrs or sharp edges present. If so, trim
the pipe to remove
these.
•Verify correct orientation of ECO detector, that
the flow arrow on the side
of the ECO enclosure
is in the same direction as the sample airflow
•In
sert the detector into the open segment of the pipe, ensuring that the
pipe entry to the detector is square and the pipes sit correctly in the
tapered receptacles
to provide a sufficient air tight seal between them
•DO NOT GLUE THE PIPES TO THE DETECTOR.
This is not necessary
and is an obstacle to future maintenance
•
If the gas test port is not to be permanently connected, ensure that the
blanking plug supplied with the unit is fitted firmly in place.
•Alternatively, if a permanent connection is to be made
to the gas test port,
use 6mm OD pipe to connect to the integrated pipe interface
is securely fitted and that it is closed at the opposite end during normal
operation.
•When mounting the ECO detector, ensure that
device is oriented such th
the Status Indicators are visible for inspection purposes.
