HSS Hire Safe and Sure 34074 Troubleshooting guide

Area Multi-Gas
Detector
A gas detector designed to detect the
presence of Methane, Hydrogen
Sulphide and Carbon Monoxide and
Oxygen.
Operating & Safety Guide SS042
During use, the alarm L Ds will flash and a single
tone alarm will sound if the battery power drops
to a low level. 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.
If one of the three gasses is detected in the
atmosphere or the level of Oxygen drops,the red
alarm L Ds will flash in quick succession and the
audible alarm emits a fast warbling noise at
approximately 104dB.
The back light will come on and the word ‘ALARM’
will flash on the display next to the gas in question.
If the alarm sounds, evacuate all personnel from
the contaminated area.
LINKING TWO OR MOR UNITS
The Area Multi-Gas Detector can be linked to one
or more additional units.
The advantage of this is, if one unit goes into
alarm, all the other units linked to it will also go
into alarm to give warning over a greater area.
To link the units together, ensure all the units are
fully charged (see ‘ELECTRICAL SAFETY’) and switched
OFF.
Unscrew the cover on one (or both if connectin
more than two units) of the interconnection sockets
and connect a link lead to it. Connect the other
end of the link lead to the interconnection socket
on the second unit.
Where more than two units are to be connected,
simply continue linking from one to the next.
You can now switch each unit ON and wait until
all have carried out their self-test sequence.
When one unit goes into an alarm situation its L Ds
will flash and the audible alarm will sound as normal.
The other units will sound an audible alarm but
their L Ds will flash at a slower rate enabling the
operator to locate the alarm area.
If the alarm sounds, evacuate all personnel from
the contaminated area.
Never push the equipment beyond its design
limits. If it is unsuitable for the task you are
performing DO NOT US OR R LY ON IT. Contact
your local HSS Safe and Sure Depot for advice.

ELECTRICAL SAFETY
GENERAL SAFETY To recharge the battery, remove the unit to a NON
HAZARDOUS AR A.
Unscrew the charge socket protective cover then
plug the charge lead into the charge socket (see
illustration). The built in charger is designed to plug
straight into a standard 230V 13A earthed power
socket.
Switch the supply ON and observe the two charge
indicator lamps.
The red lamp indicates a fast (full) charge whereas
the green lamp indicates a trickle charge. The unit
is ready to use when a trickle charge is indicated.
Recharging will take between six and eight hours.
Once charged, switch the supply OFF and

water, over sharp edges or where they could trip
someone.
Switch the unit ON by pressing the ON button.
The alarm will sound and the red ‘alarm’ L D will
flash for approximately 5 seconds.
The unit will then perform a self-test and will

voltage must read above 6.4V, if it reads lower,
recharge the unit (see ‘ELECTRICAL SAFETY).
GETTING STARTED
During the self-test, if the unit has passed its due
date for re-calibration, ‘Calibration due’ will show
on the display, the red L D will flash and the alarm
