1. INTRODUCTION
ApexisagasdetectionsystemthatconsistsofaTransmitterUnit,acertiedgassensorandaset
ofaccessories.TheTransmitterUnit,CertiedSensorandCertiedJunctionBoxaccessoryareall
certiedforuseinpotentiallyhazardousareasandareprotectedagainstwateranddustingress
to IP67.
Typical working environments are oil and gas distribution, petroleum extraction and chemical
manufacture.
System installation is straightforward. Components should be installed in accordance with the
procedures described in this handbook and to local or national installation codes of practice.
The Transmitter Unit acts as the local system controller and features a large LCD screen and
four control buttons that are used for operator interaction. Control of the system is implemented via
a system of software-driven hierarchical menus that include such operations as cartridge change,
systemconguration,etc.Remotecontrolofthesystemcanbemadeviaanoptional
digital interface.
TheTransmitterUnitcanhavetheCertiedSensorttedtoitlocallyormountedremotelyusinga
CertiedJunctionBoxandadditionalcablingupto100metreslong.
TheTransmitterUnitprovidesa4-20mAoutput,aswellasanoptionaldigitaloutput.Relaysfor
operating locally-wired devices, such as lights, horns, etc. are included. The range of accessories
enhances operation of the system and includes a collecting cone, weather protection, etc.
TheCertiedSensoriscompatiblewitharangeofmorethan40sensorcartridgesthatusecatalytic
bead,thicklmandelectrochemicalcells.
The interchangeable sensor cartridge determines which gas is monitored. All gas cartridges are fully
calibrated when supplied.
TheCertiedSensorusesintrinsicallysafecircuitstodrivethecartridges.Cartridgesmaytherefore
be exchanged without powering down even in the presence of an explosive gas atmosphere.
Field calibration of the sensor, if required, is also possible. The cartridges available are listed in
Appendix A.
The output from the sensor provides a gas concentration reading that is displayed on the LCD
screenonthefrontoftheTransmitterUnitandisalsotransmittedonthe4-20mAoutputandthe
optional digital interface.

2. OVERVIEW
2.3.3 Flow Housing
Part Number: 2110B2140
The Flow Housing accessory provides a means of applying gas to the sensor for calibration and test
(for details see section 4.7). It can also be used in sampling systems where a sample of gas is drawn
through a tube to the sensor. Conforms to CSA C22.2 No. 152whenttedtotheCertiedSensor
withspeciccartridgesinstalled.Seespecicationsfordetails.
Itprovides:
 • Twoports8mmI/Dtotake6mmtubing.
 • Asealtostopgasdilution.
Thehousingworksirrespectiveofwhichpipethegasisappliedtoandowsgasacrossthefaceof
the sensor rather than onto its face.
The difference in reading between a calibration made with the Flow Housing accessory and one
madeunderdiffusionconditions(inatankofstillgas)islessthan30%.TheFlowHousingissuitable

2.3.4 Weather Housing
Caution: This accessory should not be used for calibration purposes.
This accessory is not recommended for use in still air conditions.
Part Number: 2110B2150
2. OVERVIEW
The Weather Housing accessory protects the sensor from hosing down/ cleaning operations and
from extreme weather conditions, (e.g. torrential rain, storms, gales etc.). Conforms to CSA C22.2
No. 152whenttedtotheCertiedSensorwithspeciccartridgesinstalled.Seespecications
for details.
Theweatherhousingshouldnotbettediftheoperatingenvironmentofthesensordoesnotrequire
the additional protection afforded. In still air conditions the gas is transported to the face of the sinter
is by diffusion only. Under such conditions the weather protection will slow the rate at which gas can
reach the sensing element and consequently the speed of response of the sensor to gas will
be reduced.
As well as providing weather protection the housing also provides a means to directly inject gas to
thefrontofthesensorviaa1/4in.O/Dnozzleforgasresponsechecking.Therecommendedow
rate for response checks is 1 litre per minute. Accuracy of reading is not guaranteed. Do not carry
outresponsechecksatwindspeedsgreaterthan10m/s(22mph).
Theaccessoryisattachedtothesensorbymeansofabayonettting.
Note: The sensor will exhibit an increased reading(or indication) to gas with higher wind speeds.
 Fittingtheweatherhousingwiththesuppliedhydrophobiclterwilleliminatethiseffectbut

145mm
The Sunshade prevents excessive heating of the sensor by direct sunlight. Conforms to CSA C22.2
No. 152whenttedtotheCertiedSensorwithspeciccartridgesinstalled.Seespecications
for details.
Thesunshadeisttedtothesensorbodybymeansofaclamp.
2.3.6 Oxygen Transducer Adaptor
The Oxygen Transducer Adaptor is supplied with the Oxygen cartridge and is necessary because the
depth of the Oxygen cartridge is more than that of the other gas cartridges.
TheadaptorisattachedtotheCertiedSensorbymeansofabayonettting.TheOxygencartridgeis
ttedrstandthesensorcaporaccessoryisthenttedtotheadaptorbymeansofabayonettting.
2.3.7 Filters
OneofthreedifferenttypesoflteraccessorycanbettedtotheCertiedSensorinplaceoftherubber

3. INSTALLATION
The Apex system components can be used together in a variety of ways for different installation
requirementsinahazardousenvironment.Forinstallationsofcertiedcomponentsalsorefertothe
Control Drawings in Appendix B.
The following types of system installation are typical examplesofthosethatcanbemade:
• Apex Transmitter unit with a Certied Sensor locally mounted at the Transmitter
Unit and eld wiring from the Transmitter Unit to the system controller.
• Transmitter unit with a Certied Sensor mounted remotely in a Certied
Junction Box, with eld wiring between the two components, and from
the Transmitter Unit to the system controller.
Thischapterdescribeshowto:
• carry out the installation of a Transmitter Unit and Certied Sensor
• install an Certied Junction Box accessory with Certied Sensor, suitable for
remote operation
• install a LonWorks Communications Board in a Transmitter Unit
This is to enable the unit to be controlled and communicate over a digital network,
e.g. LonWorks.
Caution: DonotinstallacommunicationsboardintoaULorCSAcertiedTransmitterUnit
• install the system accessories
Whenttingthesystemcomponentsconsiderationshouldbemaderegardingpotentialgasleak
sources, density of the gas to be detected, probability of mechanical impacts and interference from
other equipment and apparatus.
ForoptimumperformancetheTransmitterUnitandCertiedSensorshouldbeinstalledinalocation
free from dust and direct sunlight. Sunshade and weather protection accessories for the sensor are
available when operating in harsh external environments (see 3.4).
Refertotherelevantcontrolsystemmanualforexternalnetworkconnectioninformation(e.g.eld
wiring, etc.).
