Introduction
The Argus 2 solid state thermal imager
is brought to you by Marconi Applied
Technologies, the world leader in
through smoke vision systems.
Marconi Applied Technologies, with
over 15 years experience in firefighters’
thermal imaging, continues to
produce high quality, affordable
systems designed exclusively for the
fire and rescue services.
Argus 2 uses a new high resolution
solid state detector to provide superb
quality images under the most
arduous conditions while retaining the
class-leading ergonomics of the
previous Argus system.
Through the proper use of this Argus 2
system, the user will be able to see
through dense smoke and darkness.
By detecting and displaying the
relative temperatures of objects within
the scene, it assists the firefighter to
locate the seat and spread of the fire
and to move swiftly in search and
rescue of casualties. The ability to see
in zero visibility conditions significantly
improves firefighter safety and
mobility.
Argus 2 is designed to withstand the
high temperatures, knocks and driving
spray often encountered in the fire
fighting environment.
This manual contains information
covering operation of the system and
operating techniques, user
maintenance and care of the product,
complete with a full technical
specification.

Charger and
Battery Packs
These products have been designed
exclusively for use with the Argus
(P4438), Argus Plus (P4438P) and
Argus 2 (P4455R) cameras.
The Argus charger is designed to fast
charge Argus rechargeable packs
within 100 minutes, with fully
automatic operation.
The Argus rechargeable pack is
designed to power an Argus camera
for over 2 hours from a full charge.
Inside each pack is the ‘in-pack
intelligence’; a small circuit, which
continuously monitors the charge
state of the pack and provides an
output to the ‘battery status bar’ in
the Argus Camera. This battery status
bar provides a continuous real-time
indication of the remaining charge,
allowing the firefighter to avoid
unpredicted power loss. A built-in
discharge option is included to
recalibrate the rechargeable pack
when required.
This charger is compatible with all
Argus rechargeable battery packs,
Ni-Cd (DAS533206BA/CA) and Ni-MH
(DAS533206DA).

1.1 GETTING STARTED
1.1.1 In the case with this manual
you will find the camera, a
neckstrap and two battery
packs (cases may also contain
rechargeable batteries which
are optional). The battery pack
is inserted into the handle of
the camera.
1.1.2 Check that the battery packs
contain LR6 type batteries (if
using rechargeable batteries,
check they are fully charged
before use).
Open battery door and insert
the battery pack as shown. It
will only fit in the correct
orientation. Close the door.
4
1.1.3 Turn on the unit using the
switch on the rear. This will
latch in and illuminate a red
light in the centre.
1.1.4 From two seconds after switch
on the camera will display the
Argus 2 start up screen while
the system performs a self-test
routine.
1.1.5 After 20 to 40 seconds
(depending on ambient
temperature) the thermal
image, with battery status
display in lower left hand
corner, will appear.

1.2 BATTERIES
1.2.1 Recommended Batteries
&
AA Size The most widely
available battery.
&
Type LR6 This is essential to
achieve the specified
battery life. LR6
indicates an alkaline
manganese battery
which can supply the
power requirements
of the Argus 2. Labels
such as ‘long life’ or
‘super power’ are
manufacturers’ titles
and do not necessarily
imply LR6.
&
Change all 8 All batteries in a set
must be changed
simultaneously.
$
Disposal Batteries should be
disposed of in line
with their
manufacturers’
instructions.
Note: Rechargeable packs and
charger unit are availab le as an option
to primary cell operation.
1.2.2 Battery Changing
1.2.2.1 Open the cartridge by
pressing down on the contact end
while holding the outer. The inner will
slip out of the sleeve.
1.2.2.2 Remove the old batteries and
dispose of them safely.
1.2.2.3 Insert new batteries in the
orientation shown on the inner carrier.
1.2.2.4 In order to verify the pack is
ready for use it may be tried in the
camera. A fully charged battery will
show the status display as full (see
below).
6
1.2.3 Battery Indicator
1.2.3.1 The battery pack will power
the camera for typically two hours. It is
recommended that before each BA
team enters the fire the battery pack is
fitted with new batteries (or a fully
charged rechargeable battery).
Note: The operating life of LR6
batteries varies greatly between
manufacturers and is temperature
dependent. Marconi Applied
Technologies recommend the use of
rechargeable systems at ambient
temperatures of 5 8C or less.
1.2.3.2 With a new set of batteries,
the battery bar will be at its full status
with 15 bars showing. With high
quality batteries it may remain at this
height for some minutes. The number
of bars will then progressively decrease
as the batteries are consumed. When
the battery is low, the whole battery
display will flash slowly to alert the
operator. The time remaining will
depend on the type of batteries being
used but will typically be 10 minutes.

1.3 DISPLAY GRAPHICS
The Argus 2 camera is equipped with
an advanced microprocessor based
control and user warning system. In
addition to controlling the automatic
operation of the camera to ensure the
best possible picture at all times, the
control system provides graphics on
the display to alert the user to certain
conditions as follows:
1.3.1 Battery Status
The battery status indicator is always
visible at the lower left side of the
display, except during the start up/self
test routine. See section 1.2.3.2 for
details.
1.3.2 Over-temperature Warning
As the circuitry within the camera
approaches its maximum designed
operating temperature, a warning
symbol in the shape of a thermometer
will appear to the right of the battery
status indicator. The camera will
continue to operate at this
temperature but the user may see
some degradation of the image
quality. If the user ignores this warning
and continues to operate the camera
in very high temperatures, the
temperature warning graphic will
flash.
When the temperature warning is
flashing, the camera is very close to
its absolute operating limit and the
image will start to degrade
considerably. The user must remove
the unit from the high ambient
temperature at this time; failure to
comply may result in permanent
damage to the unit.
1.3.3 General System Failure
Warning
As part of the operation of the system,
the microprocessor monitors certain
functions and displays an
internationally recognised warning
symbol if it detects a fault. The
warning, which takes the form of an
exclamation mark within a triangle,
will appear to the right of the battery
status indicator (and to the right of the
temperature warning if this is active).
The warning will appear if any of the
following faults are detected.
8
1.3.3.1 High humidity within the
sealed case assembly. This will occur if
the plastics or the case seal are
damaged and allowing moisture into
the camera.
1.3.3.2 Failure of the lens iris assembly
This warning symbol may appear
briefly during normal operation, but
the camera must be returned to an
authorised service centre or the factory
if the warning symbol remains on.
Failure to act upon this level of
warning may result in serious
damage to the system and may
invalidate the warranty.
1.4 OPERATING NOTES
1.4.1 Interpreting The Image -
Relative Temperatures
The image displayed is simply a black
and white picture of the infra red
energy entering the lens. The camera
displays relative temperature
differences between individual objects
and their surroun dings irrespective of
overall ambient temperature.
The camera is set up to display objects
at various shades between black for
cooler items to white for hotter
bodies, i.e. in a room at 20 8C a cold
drink would appear black whilst a hot
radiator would appear white. In a
room at 250 8C, however, it is possible
that the same hot radiator may appear
darker than for example, burning
materials.
9
1.4.2 Identification of Fire and
Hotspots
The camera will represent zones of
very high temperature as white zones
within the picture. Very small fires or
smouldering material will cause the
automatic iris to close down slightly
but the image of surrounding objects
will remain clearly visible.
1.4.3 Hidden Fires
It is possible that fires may be burning
or smouldering behind doors, in
ducting or indeed in wall or floor
cavities. In such circumstances the
operator should look for areas which
appear whiter when compared to the
surroundings. For example, a fire
behind a door will cause the door to
appear more white against the
background. Similarly, a white area on
an otherwise dark wall could indicate
the area of fire behind the masonry.
1.4.4 Search for Persons and Objects
The camera is not restricted to locating
fires. In many cases the firefighter will
be using the camera in a search for
casualties, to seek out dangerous
items such as fuel tanks or gas
cylinders and also as an aid to
navigation through unknown
premises.
1.4.5 Image Clarity
The sharpness and clarity of the image
provided is related to the temperature
of the scene and objects in view. A
cold room provid es little infra red
energy and less detail is detected than
in a warm environment where objects
give off significant energy. In general
the warmer the scene, the more
thermal contrast and hence greater
detail in the picture.
1.4.6 Heat Layers in Closed Spaces
In a major fire, a layer of hot gases
may build up in the upper region of
the closed space. Attempting to use
the camera in this hot layer will cause
10
the image to become featureless. By
bringing the camera down beneath
this layer the unit is able to provide the
firefighter with a clearer picture of the
scene ahead.
1.4.7 Windows and Polished
Surfaces
Glass is not transparent to long
wavelength infrared energy and it is
not possible for the operator to use
the camera to look through a window.
A white window would indicate that
the window itself is relatively warm
and may be being heated by a fire
behind it. Just as we see reflections in
glass under normal circumstances, it is
possible that the camera can detect
infrared reflections in glass, mirrors
and polished or painted surfaces. Care
must be taken to ensure that the
image seen is not simply a reflection.
Experience will give the operator
added confidence.
1.4.8 Control of Water Streams/jets
When viewed through the ARGUS
camera, water streams from hose reels
will appear black against the
background scene. The control and
aim of water flow can be monitored
by viewing the flow and its effect on
the fire through the camera. It may be
necessary, if employing a water wall,
to drop the wall momentarily to view
the effects of the extinguishing
stream.
1.4.9 Smoke Types
The ARGUS will provide vision through
all types of smoke and steam.
1.4.10 Lens Cleaning During
Operation
The came ra lens, like the BA visor, may
become obscured during use. The lens
may be cleaned with a glove or cloth if
necessary.
11
1.5 CLEANING and MAINTENANCE
1.5.1 Cleaning
After use and prior to stowing, the
camera should be cleaned. This is best
carried out using a cloth soaked with
warm soapy water.
Solvents should not be used. If in
doubt please contact your supplier.
1.5.2 Simple Fault Finding
If you are experiencing problems with
your ARGUS camera then please
follow the fault-finding flow diagram.
1.5.3 User Maintenance and
Replaceable Parts
No routine maintenance is required for
the camera. If it is not in regular use it
should be switched on for a period of
ten minutes every month to check
correct operation.
Due to the environment in which
the camera is used certain parts can
be replaced by the user. These and
the codes by which they should be
ordered are as shown on the
diagram below. THERE ARE NO
OTHER USER SERVICEABLE PARTS.

Reference numbers refer to the
sections below on how to fit these
parts.
If any damage beyond these parts
occurs please return the camera to
Marconi Applied Technologies or an
authorised repair centre. Any attempt
at repair by unauthorised personnel
may cause serious damage and will
invalidate the warranty.
1.5.4 Sidestraps (DAS532948AA)
These are retained by two screws on
each side. Once these screws are
undone the straps may be lifted off.
The replacement pair contains all new
parts required. The old strap and
screws can be discarded. Replacement
is the reverse of removal.
1.5.5 Heat Insulating Muff
(DAS532951BA)
This is supplied as one piece including
insulation and BNC cover. Also
included in the kit is the secondary lens
seal.
First remove the sidestraps as per
1.5.4. The muff can be spread at the
rear and pulled forward and upward
off the main camera.
If required the secondary lens seal can
now be replaced. This simply pulls off
the camera. To replace, align the tabs
with the slots in the main casing and
press home, moving progressively
round the lens.
Replacement of the heat insulating
muff is simply the reverse of removal.
Note: Cameras fitted with
temperature measurement require a
different outer cover with holes for the
sensors (DAS548088AA).
1.5.6 Neckstrap (DAS532982AA)
This is removed simply by undoing the
karabiner attaching it to the camera. If
any part of the neckstrap is damaged
it should be replaced as a complete
assembly.
14
1.5.7 Visor (DPP532448AA)
This flexible part clips tightly over a
flange at the rear of the camera. It is
removed by pulling backward the
material near the flange. The visor will
detach from the camera. To fit the new
part place the cutout on the visor over
the flange at the top of the camera,
pull it over one top corner. Now pull
the visor over firstly the second top
corner and then the two lower
corners.

1.7
TEMPERATURE MEASUREMENT
(Optional, designated as /TP)
The addition of two sensors to the
Argus 2 camera allows the operator to
view the average scene temperature
(within a defined area) and the
ambient air temperature. The
temperatures are displayed as an
overlay on the camera video at the
bottom right hand side of the picture.
This system is intended to give the
operator the ability to detect possible
hazards such as hot gas bottles or
tanks and a warning of high air
temperatures.
1.7.1 Spot Temperatur e
&
.
Measurement is by means of a
pyrometer mounted inside the camera
case and viewing the scene through an
aperture in the outer cover. The sensor
is protected from heat and moisture as
are the other camera electronics. The
sensor displays the average scene
temperature within the sample
window, which appears as a digital
readout at the bottom of the display.
The camera can be configured to give
a reading in degrees C or degrees F,
specified at time of ordering.

Scene temperatures between 0 8C
(32 8F) and 500 8C (932 8F) can be
displayed. If the temperature lies
outside this range a 4 or 5 symbol
appears before the reading indicating
that it is outside the possible range.
Note that if the object in the scene
does not fully fill the sample window
then a false reading may be obtained.
Care should be taken not to cover up
the sensor window (with a hand for
example) when using this system.
1.7.2 Ambient Temperature
&
The ambient temperature sensor plugs
into the RS 232 computer test point
on the front of the camera and the
ambient temperature is displayed on
the video as for the scene temperature
above. The range for ambient
temperature measurement is 0 8C
(32 8F) to 150 8C (302 8 F). If ambient
temperature measurement is not
required the sensor can be unplugged
and the readout display will
automatically be removed from the
video.

2.2.2 Operation (Normal)
Connect power to the charger as
described in section 2.1.1. Wait for the
STATUS indicator to show green. Insert
a pack into the front panel slot,
contact end first. The CHARGING
indicator will illuminate showing the
charger has entered the fast-charge
mode. The charge bargraph will
indicate the amount of charge
present.
When the fast-charge mode is
completed the CHARGING indicator
will extinguish and the CHARGED
indicator will illuminate, showing the
trickle charge mode has started. This
mode will top up the battery to full
capacity.
The charge bargraph will indicate
100% when the pack is fully charged.
A pack may be removed from the
charger at any time. The available
charge will be proportional to that
indicated on the charge bargraph.
It is recommended that the packs are
left in the charger for 2 hours after the
CHARGED light has illuminated, to
allow them to achieve full charge
capacity. A pack may safely be left in
the powered charger indefinitely.
CAUTION Do not leave a pack
in the charger with no power applied
for long periods; this may deeply
discharge the pack and cause loss of
cell capacity.
2.2.3 Operation (Discharge before
Charge)
(For pack electronics re-calibration)
Connect power to the charger as
described in section 2.1.1. Wait for the
STATUS indicator to show green.
Depress the DISCHARGE button before
inserting the pack. The DISCHARGING
indicator will illuminate showing the
charger has entered the discharge
mode. Release the DISCHARGE
button. The charge bargraph will show
the amount of charge present.
When the pack has been discharged
the charger will switch automatically
to fast charge mode. Operation will
then be as described in section 2.2.2
above.
22
2.3 ADDITIONAL OPERATING
NOTES
2.3.1 Conditioning New Packs or
Packs from Storage
New packs and packs which have been
unused for several weeks may be in a
state of deep discharge. In this state
upon charging, the CHARGED
indicator will illuminate before the
bargraph shows 90%. The pack will
need conditioning as follows:
1) Remove the pack from the
charger. When the CHARGED indicator
extinguishes, re-insert the pack into
the charger. The charger will enter the
fast-charge mode.
2) If the CHARGED indicator
illuminates with less than 90%
indicated on the charge bargraph,
leave the pack in the charger for at
least two hours then remove the pack
from the charger. When the CHARGED
indicator extinguishes, re-insert the
pack into the charger. The pack should
now fast charge to 100% as normal.
Note: In extreme cases it may be
necessary to repeat the conditioning.
2.3.2 Shelf Life
The pack self-discharge consumes up
to 2% of full charge per day. Packs
stored off-charge will still run a camera
for 1 hour after two weeks storage.
The charger’s mai ntenance mode
ensures that packs remain fully charged.
It is recommended that packs are stored
on charge, or routinely charged-up.
The shelf life of charged packs is
maximised by storage between
10 and 25 8C.
2.3.3 Memory Effects
The charger is designed to counteract
‘memory’ effects in the pack by using
a pulse charging system to condition
the pack while charging. There is no
need for a regular dischargebefore-charge routine. The discharge
before charge function is intended for
occasional use to recalibrate the inpack intelligence (see section 2.3.5).
23
2.3.4 Temperature Range for
Charging
If the temperature is below 10 8C, the
charger will automatically reduce the
rate of charge to avoid cell damage;
the STATUS indicator will show red,
the CHARGING indicator will
illuminate and charging will continue
at the lower rate. Normal fast charging
will automatically resume when the
pack temperature exceeds 10 8C.
When using the discharge before
charge mode below 10 8C, the fast
charging mode is not entered until the
pack temperature exceeds 10 8C.
The charger has a safety cut-out,
which will operate if the pack
temperature rises above 45 8C. In this
case the charger will not charge and
the STATUS indicator will show red. No
indicators or functions operate in this
state. The pack should be removed
and the charger power supply
momentarily disconnected to reset it.
2.3.5 Re-calibrating the ‘In-pack
Intelligence’
In normal use the ‘in-pack intelligence’
automatically re-calibrates the full
capacity of the pack whenever it
receives a full discharge.
If the battery pack is often used for
short periods and never fully
discharged the accuracy of the battery
status display in the camera will
reduce.
If it is suspected that there is any
inaccuracy in the bargraph display, recalibrate the pack by using the
discharge before charge function as
described in section 2.2.3.
It is recommended that this procedure
is carried out on each pack at least
once per month, to re-calibrate the
pack electronics.
Note: A reduced charge capacity may
have arisen as a consequence of
ageing or damage within the pack.
