1. SAFETY
GENERAL SAFETY
The following section provides Warnings, Cautions and Notes covering general
safety aspects for the Sentinel DTS and Multiplexer. Please read all of the safety
and operational warnings before connecting and operating this product.
WARNING! THIS IS A WARNING SYMBOL. THIS SYMBOL IS
USED THROUGHOUT THE USER GUIDE WHENEVER THERE IS
A RISK OF PERSONAL INJURY. ENSURE THAT THESE
WARNINGS ARE READ AND UNDERSTOOD AT ALL TIMES.
CAUTION! This is a Caution symbol. This symbol is used
throughout the user guide whenever there is a risk of
damaging the Sentinel DTS system. Ensure that these
warnings are read and understood at all times.
NOTES:
Used throughout the user guide to provide additional information, hints and tips.
WARNING! THE SENTINEL DTS IS HEAVY. ENSURE
ADEQUATE CARE IS TAKEN WHEN LIFTING AND MOVING
THE SENTINEL DTS. THE SENTINEL DTS SHOULD BE
MOUNTED ON A SUITABLE SURFACE OR RACK MOUNT
CAPABLE OF SUPPORTING THE SENTINEL DTS WEIGHT. THE
SENTINEL DTS WEIGHS 23KG.
WARNING! THE SENTINEL DTS IS FITTED WITH COOLING
VENTS AND FANS. UNDER NO CIRCUMSTANCES SHOULD
THESE VENTS BE BLOCKED. FAILURE TO OBSERVE THIS
WARNING MAY PRESENT A RISK OF FIRE.
CAUTION! Ensure the Sentinel DTS is connected to a suitable
electrical supply. The Sentinel DTS should be connected to a
230 or 110VAC supply.
WARNING! ENSURE THE SENTINEL DTS IS ADEQUATELY
EARTHED. FAILURE TO OBSERVE THIS WARNING MAY
PRESENT A RISK OF ELECTRIC SHOCK.
Page 2 Sentinal DTS Quick Start Guide SEN2-QSG1.0
WARNING! DO NOT EXPOSE THE SENTINEL DTS TO DAMP,
HUMID OR WET CONDITIONS. FAILURE TO OBSERVE THIS
WARNING MAY PRESENT A RISK OF ELECTRIC SHOCK.
WARNING! THERE ARE NO USER SERVICEABLE PARTS IN
THE SENTINEL DTS. UNDER NO CIRCUMSTANCES SHOULD
THE OUTER CASING OF THE SENTINEL DTS BE REMOVED.
FAILURE TO OBSERVE THIS WARNING MAY PRESENT A RISK
OF ELECTRIC SHOCK.
WARNING! DO NOT OPERATE THE SENTINEL DTS IN AN
EXPLOSIVE OR FLAMMABLE ATMOSPHERE. FAILURE TO
OBSERVE THIS WARNING MAY PRESENT A RISK OF
EXPLOSION.
CAUTION! The Sentinel DTS should only be operated by
suitably qualified personnel.
CAUTION! Never operate the Sentinel DTS if any damage is
observed. Contact Sensornet Ltd for advice.
CAUTION! Do not expose the Sentinel DTS to adverse
temperatures. This may seriously interfere with the correct
operation of the Sentinel DTS.
LASER SAFETY
The Sentinel DTS is a Class 1M laser product.
The Sentinel DTS distributed sensing system incorporates a pulsed laser device
whose invisible output radiation is potentially hazardous if viewed directly by eye.
The laser radiation emission from the laser within the Sentinel DTS is permanently
coupled into a 50/125 multimode optical fibre whose end is terminated with a E2000
angled optical fibre connector. An integral feature of the E2000 connector system is
a shuttering mechanism that prevents laser radiation from being emitted when the
connectors are disconnected or otherwise not in use.
Sentinal DTS Quick Start Guide SEN2-QSG1.0 Page 3
The Sentinel DTS should be interfaced to a test fibre, using patch cord or pigtail
assembly, fitted with a E2000 connector. The far end of the test fibre should be
terminated to prevent free-space emission of laser radiation from the fibre end. It is
recommended that where possible, E2000 connectors be utilized throughout the
optical sensing network.
Because of the potential hazard posed by laser radiation being emitted from an
exposed fibre end, the following safety warnings, cautions and notices should be
observed.
WARNING! DO NOT LOOK AT OR EXAMINE EXPOSED FIBRE
OR CONNECTOR ENDS WHENEVER THE DTS IS IN
OPERATION.
WARNING! AVOID EYE EXPOSURE TO THE INVISIBLE LASER
RADIATION EMITTED FROM FIBRE CONNECTORS OR
EXPOSED FIBRE ENDS.
WARNING! DO NOT EXAMINE OR INSPECT EXPOSED FIBRE
OR CONNECTOR ENDS USING A VIEWING AID SUCH AS AN
EYE LOUPE OR MICROSCOPE.
WARNING! DO NOT UNDERTAKE FUSION SPLICING OR
SIMILAR FIBRE JOINTING WHEN THE DTS IS IN OPERATION.
WARNING! THE DTS SYSTEM CONTAINS NO USER
SERVICEABLE PARTS AND THE PROTECTIVE HOUSING
FULLY ENCLOSES A CLASS 3B (EMBEDDED) LASER DEVICE.
UNDER NO CIRCUMSTANCES SHOULD THE PROTECTIVE
HOUSING BE REMOVED.

2. CONNECTING THE SENTINEL DTS &
MULTIPLEXER
The following connections should be made between the Sentinel DTS and if
required the Multiplexer and the installation.
Figure 1 – The Sentinel DTS and Multiplexer Connection Diagram.

INDICATORS
THE SENTINEL DTS
Figure 2 – The Front of the Sentinel DTS.
Page 6 Sentinal DTS Quick Start Guide SEN2-QSG1.0
ON STANDBY LIGHT
When illuminated, this indicates that the Sentinel DTS is in operation.
INTERLOCK OPEN LIGHT
When illuminated, this indicates that the safety interlock has been activated and the
laser is disabled.
LASER ON LIGHT
When illuminated, this indicates that the laser is operational and is emitting.
LASER ENABLE SWITCH
The Laser Enable Switch is a safety device and is used to manually prevent laser
operation. To enable laser operation, turn to the horizontal position. To disable laser
operation, turn the switch to the vertical position.
CD-RW DRIVE
The CD-RW drive can be used to load and save configuration and measurement
data.
FLASH DISK READER / WRITER
The Flash Disk Reader / Writer can be used to load and save configuration and
measurement data.
USB PORT
The USB Port can be used to insert a keyboard or USB Flash Memory Stick.
