1.1 GENERAL DESCRIPTION
The GMI PS200 series combines quality, ruggedness and
advanced technology in a user friendly, portable gas detector.
It is compact, lightweight, water resistant, extremely robust
and is suitably certified to recognised International Standards.
The PS200 is designed for confined space monitoring, for
example, in sewers, underground piping, or within tanks and
other personal monitoring applications. With audible, visual
and vibrating alarms, it provides early warning of dangerous
gas levels.
The instrument is available as either a pumped or diffusion
model and is powered by an internal Li-ion (lithium ion)
rechargeable battery with minimum operating time of 14 hours
for non-pumped operation (8 hours for pumped operation).
Maximum recharge time is 4 hours.
Operated via two push buttons, this instrument provides the
user with a simple to use, yet state-of-the-art, gas detector.
(Fig. 1-1).
The PS200 series features high visibility LED’s, a display
that changes colour from green to red when an alarm is
present, a sounder with a 90dB minimum output and a
vibrating alarm. Users can be confident that, should gas levels
exceed configured threshold limits or a sensor / flow / battery
fault exists, a clear and unmistakeable indication is evident.

ALARMS
4.1.1 Flammable LEL Alarm Limit
Two alarm levels, ‘HI’ and ‘HIHI’, are available, each with
different pitch and tone. All alarms are user configurable to
meet the specific needs of different companies.
4.1.2 Over-Range Flammable Gas Alarm Function
The flammable sensor is designed for use in the LEL range
only. Exposure to high concentrations of flammable gas, such
as lighter fuel, can damage the flammable sensor. If the
flammable gas readings exceed 120% LEL, a safety alarm
will be activated. The instrument should then be switched
OFF and returned to fresh air.
4.1.3 Oxygen (O2) Alarm Limits
Three alarm levels, ‘HI’, ‘LO’ and ‘LOLO’ are available, each
with different pitch and tone. All alarms are user configurable
to meet the specific needs of the end user.
4.1.4 Toxic Alarm Limits
When operating normally, the instrument calculates the Short
Term Exposure Limit (STEL) and Long Term Exposure Limit
(LTEL), known as Time Weighted Average (TWA) readings,
for each toxic gas range alarm. TWA alarms are
programmable for each toxic range fitted to the instrument.
Additionally, two alarm levels ‘HI’ and ‘HI HI’ are available.
Note: A Time Weighted Average (TWA) value is the mean
average gas level over a specific period. The STEL is 15
minutes and the LTEL is 8 hours. Typically, TWA alarms make
the instrument single user applicable. An option is available
to restart the averaging after each instrument switch-off, thus
allowing for multiple user application.
4-3
USER HANDBOOK
Note: The toxic gas alarm levels – instantaneous, STEL and
LTEL are set at the time of instrument manufacture. It is
important that the user ensures that the levels are in
accordance with their company’s alarm levels and with health
and safety legislation. The alarm levels may be changed, if
required, via the instrument set up software, or as detailed in
the optional ‘CONFIGURATION HANDBOOK’ (Part No.
64182).
In the following examples, Fig. 4-1 illustrates a 4-gas
instrument signalling a ‘LO LO’ Oxygen alarm and Fig. 4.2
shows a 4-gas instrument signalling a ‘HI HI’ LEL alarm. If
more than one gas alarm level is exceeded, the gas value will
flash for each gas type in alarm.

the alarm level.
If alarm configuration allows muting of audible alarm, the
following applies:
Non-latching: Once alarm has been muted, the audible alarm
is cancelled for a period of 60 seconds, and if gas
concentration during that time falls below alarm set point, the
visual alarm clears automatically.

USER HANDBOOK
Latching: If audible alarm has been muted and if gas
concentration during that time falls below alarm set point,
visual alarm requires to be acknowledged to clear.
4.4 HIGH FLAMMABLE GAS OVER-RANGE ALARM
Caution: Exposing the LEL sensor to concentrations of
flammable gas above 100% LEL can damage
the sensor.
In order to protect the user from danger in the event of the
flammable gas (LEL) sensor being over exposed to a high
concentration of flammable gas, the instrument has an overrange alarm.
If the LEL sensor is exposed to a gas reading above 120%
LEL, the instrument vibrates, the displayed value changes to
4 rising arrows, the backlight illuminates red, the tone of the
audible alarm changes, and the visual alarm LED’s flash
