Air Inlet/Outlet Pipe Connections
The tapered shape of the air inlet/outlet port of the ECO is designed to accept standard

Flow Shutoff
Due to the effects of pressure variations across an installation it is recommended that
a suitable shutoff valve is installed immediately before the ECO in the pipe work, i.e.
on the sample inlet side. This will help to prevent ambient pressure differentials caused
byaggressiveairconditioningfromgeneratingsampleowthroughtheECOduring
calibration when the aspirator is shut off.
DuringcalibrationorbumptestingnoairowshouldpassthroughtheECOdetector.The
shut off isolation valve will provide a simple means of accomplishing this.
Notes: Do not install your ECO detector if there are any signs of shipping damage.
Inform your distributor if there is any visible damage.
Check that the model of the ECO detector is correct as per the design
specicationsofthesite.Refertothemodelnumberlocatedonthemain
product label and ensure that the gas types and ranges are of the correct
specication.
When using VESDA ECO with the VESDA VFT-15 or ICAM IFT-15 detectors a
special adapter is required, part number ECO-FT15.

2. Remove a straight section from the pipe at the preferred location within the pipe work.

3. Ensure that the cuts on the pipe are perpendicular to the pipe and that there are no
burrs or sharp edges present. If so, trim the pipe to remove them. Ensure the pipe is
free of any debris.
4. VerifythecorrectorientationoftheECOdetector,inthattheowarrowonthesideof

5. Insert the detector into the open section of the pipe, ensuring that the pipe entry to the
detector is square and the pipes sit correctly in the tapered air inlet/outlet ports and
provide an air tight seal.
Note: 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 to a remote gassing
pipe,ensurethattheblankingplugsuppliedwiththeunitisttedrmlyinplace.
Alternatively, if a permanent remote gassing pipe is to be installed, use 6 mm

6. Ensure that the device is oriented such that the status indicators are visible for
inspection purposes.
7. Ensurethatthereissufcientaccesstotheenclosurecoversuchthatitcanbe

8. DuringcalibrationnoowshouldpassthroughtheECOdetector.Installingashut
off isolation valve in front of the ECO detector and shutting the aspirator off during
calibration will help achieve this result. Ensure that the valve does not restrict the inside
diameter of the sample pipe. Installing a clean out tee in front of the valve to facilitate
routine pipe network cleaning, without having to remove the ECO detector or pipe is
also recommended.

RS485 Interface Connection
ECOgasdetectorsareequippedtoprovideserialcommunicationtoXtralisconguration
and monitoring software or for interface to 3rd party higher level systems.
Theserialinterface(ModbusRTU)providesmulti-dropserialcommunicationcapabilityto
a number of ECO gas detectors via a screened twisted pair cable. When used to interface

For interfacing ECO to 3rd party higher level systems, please refer to the separate ECO
Modbus interface guide with regard to register mapping, data types and data limits.
The Modbus RTU interface on the ECO detector is implemented using the EIA-485
standardforthephysicalinterface.Thisisatwo-wiredifferential,halfduplexconnection

By default, the Modbus protocol settings for an RS485 interface are:
• Baudrate 19200
• Parity Even
• Stop Bits 1
These are the default settings programmed into the ECO at shipping. ECO detector is

Communication
USB: TheUSBportisusedforinitialcongurationandlocalmaintenanceorservicing
of the detector using a PC installed with Xtralis VSC software. Install Xtralis VSC prior
to connecting the detector to the computer to ensures that the required USB drivers are
present.
Power Up
Connect 24 VDC power to the PWR IN terminal.
On power up:
• The Power LED illuminates and the detector runs a series of self-diagnostic tests.
• If there is a fault, the Fault LED illuminates. To identify the fault, check theActive Event
List for the detector using Xtralis VSC.
Conguration
Forinitialconguration,useaUSBconnectionandtheXtralisVSCsoftware.
• After installing ECO gas detector, make sure VESDA is working properly.
• Normalizetheairow.Thistakesapproximately6minutes,afterwhichtheowreading
should be close to 100.
• Reset the detector. It should now be running without faults.
