INTRODUCTION

The Millennium series is Net Safety's latest innovation in a line of continuously evolving industrial gas detectors. The microcontroller based system provides fast,
accurate and continuous monitoring of gases in extreme environments.

THE PRODUCT

The Millennium Basic is available with analog or relay output, and both are explosion-proof, Class 1, Division 1 for hazardous areas, combustible gas detectors for
use with the SIR100 sensor (methane/propane).

THE MANUAL

The manual has been designed to make installation of the Millennium product easy . To ensure proper installation, follow the 7 simple steps outlined in the following
pages. Throughout this manual are tips and warnings to make your installation experience more efficient. If you encounter problems during operation, consult the
troubleshooting section or contact your sales representative.

STEP 1 — PLAN

LOCATE CONTROLLER/SENSOR

Prior to the installation process, a location plan for placing the Controller and
Sensor should be developed. Although there are no absolute rules for
determining the quantity and location of a sensor or controller, the following
points should be considered when planning the installation.

• Locate the Controller where it will be accessible and visible.

• Carefully locate the sensor in an area where gases are most likely to
accumulate.

• Use redundant systems to enhance protection and reliability.

• Light gases tend to rise; heavy gases tend to accumulate in low areas.

• Consider air movement patterns within the facility.

• Consider the construction of the facility (such as trenches where heavy gases
may accumulate or peaks where light gases may accumulate).

• Seek advice from experts knowledgeable about the primary gas to be
detected.

• Use common sense and refer to various regulatory publications that discuss
general guidelines for your industry.

The two most common installation options are as follows:

Option 1

The Sensor is attached directly to the Controller. A calibration cup is slipped
onto the bottom of the Senor and the gas is attached to the side calibration
fitting.

See "Sensor Separation—A

NALOG OR RELAY" on page 7 for detailed

instructions.

See "Wiring Controller and Sensor—A

instructions.

Option 2

Locate Sensor separate from Controller using a Junction Box.
The Controller is located near eye-level. Conduit is run from the Controller to

the Sensor. A Junction Box is used to connect the conduit from the Controller to
the Sensor. A Calibration Cup can be attached to the Sensor. Tubing can be run

TIP:

The Calibration Cup prevents air circulation af fecting the calibration
process and concentrates the gas during calibration. If the Calibration
Cup is not used, the area must be free of drafts or wind and the flow rate
of calibration gas must be 3.0 liters per minute or greater.

from the calibration cup to a convenient location accessible for calibration gas
to be injected.

STEP 2 — INSTALL

UNPACK

Carefully remove all components from the packaging. Check components
against the enclosed packing list and inspect all components for obvious
damage such as broken or loose parts.

If you find any components missing or damaged, notify the distributor or Net
Safety Monitoring immediately.

The Controller Housing

13.14”

The Controller is explosion-proof, Class 1, Division 1, Groups C, D for
hazardous applications.

It is designed as a 1-man, intrusive calibration.
The Sensor can be attached directly to the Housing or separated using a junction

box.
To remove the cover, simply screw the cover counter clockwise.

The Sensor

The SIR100 combustible gas sensor detects 0-100% LEL for methane/propane.
