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.
