The purpose of CO2 detection
CO2 is a colorless, odorless gas which normally
exists at a concentration of about 0.04% in the air
we breathe. CO2 gas does not support life and in
concentrations above 4% it has dangerous effects
(IDLH). The equipment that stores and uses CO2 is
designed for normal safe operation when properly
maintained. But leaks may cause High concentrations
of CO2 creating unsafe conditions.
The equipment that stores and uses CO2 is designed
for normal safe operation when properly maintained.
Leaks may cause High concentrations of CO2
creating unsafe conditions. CO2 is 1 ½ times heavier
than air. It will concentrate in low areas posing a risk
of asphyxiation/suffocation to anyone in or entering
those areas. The quantity of gas in relation to the size
of a room or space is what defines if an area is to be
considered a confined area.
The CO2 Safety System continuously monitors
CO2. The system is designed to monitor CO2 gas
concentration and to provide an alarm at four pre-set
elevated levels.
CO2 concentration levels (%) and
effects
(%) Effect
20.0 Death within a few seconds.
10.0 Convulsion, Unconsciousness, Death.
7.0 Dizziness, Vomiting, Headache, Reduced
blood supply to brain.
4.0 IDLH -Immediate Danger to Life and Health.
3.0 Normal exhale concentration; increased
breath and pulse rates.
1.0 Shortness of breath possible.
0.5 Maximum for working conditions (TWA 8 hr.
PEL).
0.1-0.2 Recommended max value in public areas.
0.04 Fresh air.
TWA (Time Weighted Average)
In most countries the Hygienic Limit Value over 8
hours/day is 0,5% or 5000 ppm. It is considered
unhealthy to be exposed to more than this value
during an 8-hour working day. In Europe there is EU
Legislation regarding TWA. (Patented measuring
method).

II General Description
Product description, performance
and intended use
The Carbon Dioxide (CO2) Safety System is
designed to measure CO2 concentration in a
confined space environment. It is designed to provide
an alarm in the event that a CO2 level exceeds the
preset alarm levels.
The basic Mk 9 CO2 Safety System is a precision
instrument comprising one central unit (with a digital
display), one (up to eight) sensor unit/s, warning
lamp/s and horn/s. A separate power supply (100-240
VAC) supplies power to the system. Please observe
that you have to connect the appropriate plug adaptor
to the power supply depending on which country you
are in. The sensor uses infrared analysis for detecting
CO2. The system provides visible indication of CO2
levels in the area where the sensor is located.
When installed properly, the CO2 Safety System
will continuously monitor the CO2 concentration
where a sensor unit is located. A green light emitting
diode (LED) on the central unit indicates normal safe
conditions. If ambient conditions at the sensor unit
reach a CO2 concentration level of 1.5% (preset
low alarm), the central unit will emit an intermittent
audible tone and the « low alarm » red LED will blink
and a remote warning lamp will be activated. This
will also happen if the TWA for 8 hours also reaches
5000 ppm. The difference can be acknowledged on
the display.
A properly connected system will begin to operate
immediately after a Self-diagnostics program has
been made by the System, when plugged into to a
(100-240V AC) power outlet. No additional start-up
procedure or adjustment is necessary.
In the event of a system fault, the yellow « error »
LED is activated and a beeping tone will be made by
the Central Unit. The error will be described in the
display until the fault has been rectified and cleared/
reset on the central unit.
In case of Alarm, the buzzer in the Central Unit may
be muted by pressing the reset button shortly.
The alarm can only be totally cleared/reset when the
CO2 level drops below 1.5% (the low alarm). At a
Low Alarm, one person, supervised by another, may
check for the leakage cause.
If ambient conditions at the Sensor reach a
concentration level of 3% or more, the Central Unit’s
High Alarm will activate a constant sound signal, the
red LED will light continuously and the digital display
will show ALARM. The room in which the sensor
is located must not be entered when the CO2
concentration is over 3%!
Emergency services must be contacted!
Temperature monitoring
Selectable Temperature Alarm
The Sensor Unit has a temperature alarm function
that can be activated via the DIP-switches on the
Sensor. If activated, the current temperature at the
Sensor will be shown on both the Central Unit and
the Sensor. The temperature alarm is activated if
the temperature at the Sensor is lower or higher
than +1°C to +10°C / +34°F to +50°F. For more
information, see the CO2 Sensor section.
The functions of the Central Unit
The Central Unit is multi-lingual. The measurements
from the sensor(s) and alarm indications are shown
on the display. An information text for all Alarm and
Error conditions is also shown on the display. If
more sensors are connected their values are also
displayed, indicating which sensor the value is from.
On the right side of the display, there is a sound
mute/reset and test button .
The Central Unit also has an alarm memory that
remembers and reactivates any alarm after a power
interruption.

Installation III
OBSERVE!
“All persons responsible for the operation and
maintenance of this equipment must read and
understand the safety and operating information
contained in this guide. Installation and service
of this equipment should be performed only by
professionals. The function of the equipment will be
impaired if it is not properly installed.”
Disconnection from supply source: When installing
the CO2 Safety System to the power net, please
ensure that the fuse that the system runs on is clearly
marked. This makes it easy to disconnect the power
to the system, if needed.
Plug the power supply into an electrical supply
outlet before carefully taking the components out of
the box, this to insure that it runs correctly before
installation. NOTE: Be aware of the very high
sound from the horn.
Notice that all LEDs on the Central Unit and the
Sensor will illuminate and the built-in buzzers
will beep during start-up, this is part of the Self-
diagnostics program. After approximately 3 seconds
all external horns and/or strobes (connected to
the Sensor) will be activated for approximately 5
seconds.
Determine proper location for
system components
CO2 Sensor
• The CO2 sensor should be placed in the room
where CO2 equipment is being used/distributed
and/or where CO2 is likely to accumulate in the
event of leak. Please observe that this does not
necessarily have to be where the CO2 is stored,
for example when the CO2 is stored outside.
NOTE: CO2 is a heavy gas that will collect in
low areas and in confined spaces.
One sensor unit will monitor an area up to about
5 meters from the place that it is mounted,
therefore it is important/essential to place the
sensors in the correct places.
It is VERY IMPORTANT to be aware that the
danger is always in relationship to how much
CO2 is used (stored) in relationship to the volume
of the room in question.
It does NOT have to be BULK CO2 STORAGE
CONTAINERS to be dangerous!!!
NOTE: If a room only has mechanical
ventilation, it should have a sensor, since the
ventilation can be turned of.
The sensor should be mounted 12” / 30 cm
from the floor to the bottom of the sensor. It
should be installed horizontally on a wall with
the cable outlets pointing downwards, so it
has clear exposure to room air but is mounted
away from ventilation inlets or outlets. Its digital
display should be clearly visible. Try to position
the Sensor where it will be out of the way of
moving objects. Use the supplied screws and wall
anchors.
• A warning Horn/Strobe, must be located where it
is clearly visible at any entrance to the area being
monitored. This may require more than one Horn/
Strobe.
A Horn/Strobe should also be mounted on the
wall above the sensor.
Central Unit
Place the Central Unit horizontally on a wall with the
cable outlets pointing downwards, in a dry location.
It should be placed at a height where it can be easily
seen but where it is least likely to be damaged by
items such as mop handles or boxes being moved.
Use the supplied screws and wall anchors.
• The Central Unit must be placed outside the
area or room being monitored, preferably in the
manager’s office. If the Central Unit is placed in
the manager’s office it is recommendable that a
Horn/Strobe is mounted outside the door to make
the personnel observant that there is an alarm
situation.
NOTE: The Central Unit and Sensor(s) are
connected to each other by cables that may need
to be disconnected for purposes of cable routing
or installing a longer cable. When reconnecting
cables make sure they are properly
reconnected to their proper connectors. Refer
to the connection diagram on page 12 for
assistance.
Try to route all conductor cables in cable conduits for
a neat and safe installation.
• Be sure the reset button can be pushed without
obstructions.

10
III Installation
• Mount the Plug-lock so that the power supply
cannot be disconnected without the use of
mechanical tools.
• Make sure the Central Unit is not placed in the
risk area that is being monitored!
Removal of the cover
If the cover of the Central Unit or Sensor Unit needs
to be removed please observe the following order of
screw reassembling.

Installation suggestion
Route the cables in the cable channels on the back
of the enclosure.
Horn/Strobe
The CO2 Safety System is equipped with a pre-wired
Horn/Strobe. Its power cord has a blue connector
at the end terminal that is connected to the splitter,
marked with a blue dot.
1. Mount the horn/strobe in a proper location above
the CO2 sensor. Refer to the description and
diagram on page 12.
Warning Beacon (Optional US)
The CO2 Safety System is equipped with an optional
prewired warning beacon. Its power cord has a blue
connector at the end terminal that is connected to the
splitter, marked with a blue dot.
1. Separate the beacon from its mounting base
using a counter clockwise twist.
2. Mount the base in a proper location using screws
through the knockouts on the « back » of the
base. Refer to the following description and
diagram on page 12.
3. Attach the beacon to its base using a clockwise
twist.
An additional beacon can be added, if necessary,
at another entrance to the room being monitored.
Simply add a 1-2 splitter and connect the second
unit.
To ensure proper operation, the combined
distance between (farthest) Warning Beacon,
Horn/Strobe, Sensor Unit, and Central Unit,
should not exceed 300 m (980 feet).
