1. INTRODUCTION
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).
