General information on O2-detection

NITROGEN GENERATORS
Please note that if a nitrogen generator is being used in the area where the O2 sensor is installed, the excess oxygen created by the nitrogen generator must be led out of the area. It is not allowed to use the O2 sensor in the area if the oxygen is not led out. The LogiCO2´s O2 Safety Systems measures the O2 concentration in an enclosed space environment and provides alerts/alarms in the event that O2 levels in that space reaches the pre-set alarm levels.
The O2 sensing devices uses optical analysis for detection of O2.
Depending on how the sensors alarm levels are set, if a sensor detects a low or high O2 level, the O2 sensor alerts via sound and light-diodes as well as remotely connected warning lamps, horns or horn/ strobes which will be activated. If it is connected to the Mk9 central unit it will also display which sensor has detected an O2 level alarm.
First after a self-diagnostics program has been done by the system the sensor will begin to detect O2 levels when powered on. The system is delivered pre-connected. With auxiliary kits, functionality can be substantially extended. There is a set which is comprised of one O2 sensor, one central unit, one horn/strobe as well as appropriate signs. As well as one with the Stand alone version.
O2 concentration levels (%) and effects(%)……………. Effect

General LogiCO2 Safety System description

LogiCO2´s O2 Safety Systems measure O2 concentration in an enclosed space environment and provides alerts/alarms in the event that O2 levels in that space reaches a pre-set level. The O2 sensing devices uses an optical sensor for accurate detecting of O2. When installed properly, the system will continuously monitor the O2 concentration where a O2 sensor is located.  

Depending on how the sensors alarm levels are set, if a sensor detects a low or high O2 level, the O2 sensor alerts via sound and light and remotely connected warning lamps, horns or horn/strobes will be activated. The central unit will alert with sound and display which sensor that has detected a low or high O2 level. A properly installed system will begin to detect O2 levels when powered on, after a self-diagnostics program has been made by the system.
The system is delivered as pre-connected sets with auxiliary kits to extend the function of the sets. The sets are comprised of one or more O2 sensors, with auxiliary central unit/s, horn/s and relay boxes.
Examples of sets and kits:

Test and installation

LEGAL NOTICE
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 power supply source: when installing the O2 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.
It is very important to be aware that the O2 Safety System does not function if disconnected from power mains.

3.1 Testing set, BEFORE INSTALLATION
The different sets are delivered pre-connected in the package. Always test the set before installation to verify proper function! NOTE: Be aware that during the test a very loud sound will be emitted from the horn.

1. Open the box and carefully take the components out of the package.
2. Find the power supply in the package and attach the correct mains-adaptor for your country’s outlet, then connect the power supply to the electrical outlet. The set should now activate.
3. If you test a Mk9 detector set, please check that all LEDs on the central unit and the sensors illuminate and the built-in buzzers beep, this is part of the self-diagnostics
   program. Approximately 3 seconds after connection all external horns and/or strobes (connected to the sensor) should be activated for approximately 5 seconds.
4. Now your set is tested and you can start the installation.

Note! If additional kits are to be installed. Please check appropriate part of the manual for correct DIP-switch setting (ID-address).
3.2 Installation of the O2 Sensor
Correct placement of the O2 Sensor
The O2 sensor should be placed in the room where there is a risk for unsafe oxygen concentration – this would be at the distribution points of the nitrogen, nitrogen generator or nitrogen tank as well as mixed gas with nitrogen. Please observe, this does not necessarily have to be where the asphyxiant gas is stored, for example when it is stored outside and the gas is routed into the building via pipes.
It is also VERY IMPORTANT to be aware that the danger always is relative to how much asphyxiant gas is used and stored in relationship to the volume of the room in question.
NOTE: If the room has only mechanical ventilation, it should have a sensor.Installation of the O2 Sensor
The O2 sensor should be installed at breathing height, between 150-180 cm/5-6 feet from the floor.
Try to find an installation position where the unit is least likely to be damaged. Mount the O2 sensor with supplied mounting screws.
3.3 Installation of the Horn/Strobe      

1. The horn/strobe/s must be installed on the wall above the O2 sensor, approximately 2-2.4 m/80-96 inches (as per NFPA 72) above the floor, clearly visible from any entrance of the area being monitored. It is recommended that a second horn/strobe be placed OUTSIDE the area being monitored, preferably placed over the door/s leading to the monitored area. This will require more than one horn/strobe. Mount the unit with supplied mounting screws.
2. Mount the included warning signs so they are clearly visible, next to or above the horn/strobes, in a permanent way.

3.4 Installation of the Central Unit

1. If your set includes a central unit, it must be installed outside the area or room being monitored, for example on a wall in the manager’s office. The central unit must be installed at a clearly visible and reachable height.
2. Mount the included information signs clearly visible, next to or above the units, in a permanent way.

3.5 Installation and connection of the cablesThe different units are connected to each other by cables. The blue marked cable is used for signalisation (horn/strobe, warning beacon and remote control box). The red marked cable is for communication and power. Please observe, all cables have splitters at the end to facilitate extended cable lengths. When installing, the cables may need to be disconnected for purposes of cable routing.
When reconnecting, please make sure that you connect to the original splitters and connectors. Make sure to mount the protective collar seals with the tie-wraps in order to protect the connections from moisture and dust. The collar seals as well as the tie-wraps are also delivered in the box that the sensor comes in. If possible, route the cables through cable conduits between the units, for a neat and safe installation.
Protective collar seals and cable ties are included. They must be used as below to protect the RJ45 1-1 connector or RJ45 1-2 splitter from moisture and dust. 3.6 Connection of the power supply
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.
Connect the power supply to the electrical outlet.
Mount the included plug-lock so that the power supply cannot be disconnected without the use of tools.
It is also possible to order a hardwired power supply option when and were it is needed.

Calibration

Automatic calibration
The LogiCO2 O2 sensor has an automatic self calibration function activated as standard, and no manual calibrations should be needed in normal conditions.
Manual calibration
Before a manual calibration can be done, the sensor needs to be powered for at least 20 minutes, to make sure it is heated up and adjusted to the environment. Try to make sure that the room is well ventilated.
Instruction:
A more detailed instruction can be found in chapter 7.5, ”Service Mode Three”, in this manual.

1. Press and hold the button on the sensor for 10 seconds.
2. An asterisk (*) is now flashing, in the upper right corner of the display.
3. When the asterisk (*) is shown, push the button shortly. Repeat this five times in a row to enter the Calibration mode. For each correct push of the button, a dot will be shown in the lower left corner. If an incorrect push happens, the procedure starts over again, from step 2.
4. The instructions in the display will say Push the button to start calibration. Push the button shortly and a 90 second timer will start counting down. If the calibration is
   successful, the display will show “Calibration OK” and go back to Service Mode One, for 30 seconds, and then go to “normal view”.

Mk9 O2 Sensor, General information

7.1 General Description
The sensor is an O2 sensor with display that is used to monitor the O2 levels of an enclosed space. This unit can be connected to a Central Unit or to an existing Mk9 CO2 System for full functionality. Horn/strobes, flash units or external connection boxes can also be connected to the sensor for added functionality. The O2 sensor display shows the current O2 level and the current alarm settings.
The LogiCO2 oxygen sensor (O2) has a FBO oxygen sensor with built-in temperature and pressure adjustment. This means that it has an automatic altitude compansation function. The oxygen sensor is factory calibrated and measures the ambient oxygen partial pressure (ppO₂) levels. The sensor benefits from low power operation and a long lifetime, due to the optical sensing principle.
The O2-sensor is compatible with LogiCO2 Mk9 CO2 Safety System. It communicates via Modbus RTU with the LogiCO2 Mk9 Central unit and can be used together with the different LogiCO2 CO2 sensors. The unit is delivered together with a horn and strobe alarm device.
