DX100 (M)
TERMINATION UNIT
MAN0617 Issue 03 February 2003

Quick Start Guide
The DX100 (M) Termination Unit is an explosion proof active junction box that
provides a signal connection point for the Searchpoint Optima and Searchline Excel
range of gas detectors and the associated field wiring, and a mounting point for the
Searchpoint Optima and Optima Plus detectors. The unit is certified to UL and CSA
standards and is intended for use in hazardous environments.
The Termination Unit also provides a digital interface between the attached gas detector
and an RS485 link to the network controller.
Note: Gas detector digital address configuration information is not provided here but in
the DX100 Series Termination Units Technical Handbook.
The DX100 (M) provides:
• terminals for connecting the gas detector and the field cabling
•an Intrinsically Safe (IS) connection point for the Hand Held
Interrogator (SHC1)
•a local mounting point for the Searchpoint Optima or Optima Plus gas
detector
The unit features three 3/4” NPT cable/conduit entries, two terminal blocks and a voltage
clamp with a communications link entry socket
When used with an Optima or Optima Plus, one of the unit’s three cable/conduit entries
(usually the left-hand one) is used to mount the gas detector directly to the box. The gas
detectors output a 4-20mA signal that is sent via the Termination Unit and field wiring back
to the system controller.
The voltage clamp and the external socket provide the IS connection to the
Handheld Interrogator (SHC1) which allows operator interaction with the attached gas
detector to commission, calibrate or diagnose the system. Full details about the gas
detectors can be found in their respective technical documents, which include operation of
the SHC1.
Caution: Only the SHC1 Handheld Interrogator should be connected to the
DX100 (M) communication link entry socket.
This guide covers the basic on-site mechanical and electrical installation of the unit. Refer
to the DX100 Series Termination Units Technical Handbook (Part No: 2104M0701) for
more detailed information about the DX100 (M).

3. MAIN FEATURES 4. INSTALLATION
INSTALLATION
It is important before starting these procedures that the detailed information
provided in the DX100 Series Termination Units Technical Handbook about
DX100 (M) installation has been carefully considered at the planning stage.
General Installation Guidelines
1. Read the Warnings and Cautions at the beginning of this document and all the
relevant instructions before starting any of the installation procedures.
2. Identify external cable requirements and the necessary cable entry ports to be used
on the Termination Unit.
3. Refer to the documentation for the associated control system for details about
external network connection information, field wiring, interconnections, etc.
4. Refer to the relevant handbooks for details about the gas detectors.
5. Isolate all associated power supplies and ensure that they remain OFF during the
procedures. Ensure a gas-free atmosphere.
MECHANICAL INSTALLATION PROCEDURES
Mechanical Installation Guidelines
1. Identify a suitable location where the Termination Unit can be mounted. The
Termination Unit should be fitted to a flat surface.
2. When fitting a Termination Unit consideration should be made regarding the
probability of mechanical impacts and interference from other equipment and
apparatus.
3. The mounting plates for the Searchline Excel gas detectors, and to which the
DX100 (M) unit is attached, have fixing holes that are unthreaded. Unit and
gas detector system component mounting holes are threaded. For the identity
of other plate holes refer to the Searchline Excel Technical Handbook.
With Searchpoint Optima
This procedure describes how the
DX100 (M) is installed at the
mounting location and then the
Optima gas detector is fitted to the
Termination Unit.
(1) Securely fit the Termination
Unit at the required monitoring
point.
Use the two Termination Unit
mounting lugs. Ensure the
communications link entry socket connector is located at the bottom. This
fulfils the requirement to position the Optima sensor horizontally so that the
risk of fouling the gas detector's optical surfaces is reduced.
(2) Remove the Termination Unit lid.
Use the lugs on the lid to unscrew it anticlockwise from the Termination Unit
base.
(3) Fit the Optima detector to the left-hand entry.
First remove the 3/4 NPT approved blanking plug.
(4) Fit approved certified 3/4 NPT cable glands or conduit fittings to the
Termination Unit cable/conduit entries as required.
(5) Fit the external field wiring through the cable/conduit fittings and secure.
(6) Terminate the gas detector and field wiring.
Refer to Electrical Installation.
With Searchline Excel Open-Path
The DX100 (M) is fitted to the
Excel receiver’s mounting plate
and then the units are wired.
(1) Securely fit the Termination
Unit to the mounting plate
so that the communications
link entry socket connector
is located at the bottom.
Use the Termination Unit
mounting holes marked Gon
the diagram below. The box
uses two of the four holes
depending on the plate’s
horizontal orientation.
(2) Remove the Termination Unit lid.
Use the lugs on the lid to unscrew it
anticlockwise from the Termination
Unit base.
(3) Attach the Searchline Excel gas
detector's cable to the Termination
Unit.
Fit to the bottom left entry after
removing the 3/4 NPT blanking plug.
(4) Fit approved certified 3/4 NPT cable
glands or conduit fittings to the
Termination Unit cable/conduit entries as necessary.
This section shows the main features of the Termination Unit and also details
important dimensions for the unit when installing.

INSTALLATION INSTALLATION
(5) Fit the external field wiring through the cable/conduit fittings and secure.
(6) Terminate the gas detector and field wiring.
Refer to Electrical Installation.
With Searchline Excel Cross-Duct
The DX100 (M) is fitted to the
Cross-Duct mounting plate and then
the units are wired.
(1) Securely fit the Termination
Unit to the mounting plate so
that the communications link
entry socket connector is
located at the bottom.
Use the mounting holes marked
Gon the diagram below.
(2) Remove the Termination Unit
lid.
Use the lugs on the lid to
unscrew it anticlockwise from
the Termination Unit base.
(3) Attach the two cables from the Searchline Excel Cross-Duct gas detector to
the Termination Unit.
Fit the transmitter's cable to the bottom left entry after
removing the 3/4 NPT blanking plug. Fit the receiver's
cable to the right-hand entry after removing the 3/4
NPT blanking plug (see the diagram). Use suitably
approved certified glands/adaptors.
(4) Fit an approved certified 3/4 NPT cable gland or
conduit fitting to the Termination Unit cable/conduit
entry as necessary.
(5) Fit the external field wiring through the cable/conduit
fitting and secure.
(6) Terminate the gas detector and field wiring.
Refer to Electrical Installation.
ELECTRICAL INSTALLATION
Electrical Installation Guidelines
1. Isolate all associated power supplies and ensure that they remain OFF
during the procedures. Ensure a gas-free atmosphere.
2. Ensure that approved and certified cable glands have been fitted to the
Termination Unit cable entries where used for field wiring, with sealing
washers where necessary to maintain the ingress protection rating.
3. Ensure that any cable gland/conduit locking rings are fitted before terminating
the cables.
4. Make sure that a conduit sealing fitting is installed within 460mm (18in.) of the
Termination Unit on all conduit runs. The following diagram shows a vertical
conduit seal fixed in the conduit run close to a Termination Unit fitted with an
Optima unit. Excel Open-Path and Cross-Duct installations should be similar.
5.
6.
7.
8.
9.
Ensure that approved and certified blanking plugs are fitted to all unused
Termination Unit cable entries.
The Termination Unit mounting plate must be bonded to a protective earth.
Suitable crimps and/or ferrules must be fitted when connecting more than
one wire to a Termination Unit terminal.
The field terminals of the Termination Unit accept single or multi-stranded
wire from 22-12 AWG (0.326 to 3.31 mm2), 105C. Cables should be
routed carefully to avoid physical and environmental hazards such as
mechanical stress and high temperatures.
In order to ensure correct operation and to meet requirements for RFI and
EMC, it is recommended that all field cables are screened with the cable
screen connected at one end only (see the Technical Handbook).
Connect the gas detector and field wiring to the terminal blocks in the DX100 (M)
Termination Unit according to the following wiring diagrams and tables.
