GENERAL SAFETY
GETTING STARTED
The battery charger is designed to plug straight
into a standard 230V 13amp power supply.
Using electrical equipment in very damp or wet
conditions can be dangerous.
To reduce the risk of electric shock, always use a
suitable RCD (Residual Current-Operated Device)
available from your local HSS Safe and Sure Depot.
The battery is an integral part of the unit and will last
approximately 12 hours in normal use.
GETTING STARTED
The gas detector battery must only be re-charged
indoors and in a NON HAZARDOUS
ENVIRONMENT.
To charge the battery,
simply insert the unit
into the charger (see
illustration), ensuring the
unit is the correct way up.
Plug the charger into a
suitable power supply
and switch the supply
ON.
Charging is fully automatic
and the battery should
be fully charged in
approximately four to six hours depending on
battery condition.
Only use the charger supplied, any other type of
charger may cause the battery to explode.
If an extension lead is used for the charger it should
be fully unwound and loosely coiled, away from the
equipment. Never run leads through water, over sharp
edges or where they could trip someone.
Never carry or pull the charger by its power supply
cable.
Controls
Switch the unit ON by pressing the ON button. The
alarm will sound and the red ‘alarm’LED will flash
momentarily.
The unit will then perform a self-test and will display
the current battery condition. The battery voltage must
read above 5.8V, if it reads lower, recharge the unit (see
‘ELECTRICAL SAFETY).
During the self-test, if the unit has passed its due date
for re-calibration, ‘Calibration due’ will show on the
display, the red LED will flash and the alarm will sound.
If the words ‘Sensors Changed’ appear on the
display, one or more of the sensor modules may
have a fault.
If either warnings occur, DO NOT USE OR RELY ON
IT, contact your local HSS Safe and Sure Depot for a
replacement unit.
There is a backlight facility, which will illuminate the
display in situations where the lighting is not very good. To
operate the backlight press the ‘backlight’ (sun
emblem) button, press again to turn the light OFF.
The back light feature comes ON automatically in the
event of an alarm.
During use, the power LED will flash. If the battery
power drops to a low level, the power LED will flash
at a quicker rate and the unit will emit a beep.
If this happens, evacuate the area of all personnel
and arrange re-charging (see ‘ELECTRICAL SAFETY’).
To switch the gas detector OFF press both the ON
button and the blank button (see illustration) at the
same time.
BASIC TECHNIQUES
The unit is supplied with an aspirator, used to test an area
prior to entry.
Securely attach the aspirator manifold to the top of the
unit, aligning the two securing wing nuts to the threads so
that the manifold covers the sensors.
Make sure the long end pipe is fitted to one end of the
aspirator and the bulb with a short length of pipe to
the other. When activated, air is drawn in to the long end
pipe, over the sensors and out through the bulb.
Switch the unit ON in a non-hazardous area and wait
until the unit has passed its self-test.
The display will then ask “are you in clean air?”, you
should now press the button below the ‘YES’ on the
display (the ON button).
Insert the aspirator long end pipe into the work area
then squeeze and release the bulb a minimum of 20
times.
If one of the three gasses is detected in the atmosphere
or the level of Oxygen drops, the alarm will sound. The
alarm LED flashes, the backlight comes on and the word
‘ALARM’ flashes on the display next to the gas in question.
