NOTE 1: Always test your set, BEFORE INSTALLATION!
The different sets are delivered pre-connected in the package.
Be aware! During the test a very loud sound will be emitted from the horn.
The test procedure is described in chapter 3.1 in this manual.
NOTE 2: Remember to perform a startup calibration when the system is installed.
The calibration procedure is described in chapter 4 in this manual.

- Page 3 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 a confined space environment and provides alerts/alarms in the event that O2 levels in that space reaches the pre-set alarm levels.
- Page 4 Central Unit O2 Sensors 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.
- Page 5 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.
- Page 6 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.
- Page 7 2-2.4 m / 80-96" 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.

Page 8: Connection Of The Power Supply
Installation and connection of the cables Blue The 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. -
Page 9: Startup Calibration
AUTO-CAL must be deactivated by setting the DIP-switch number 6 (on the printed circuit board) in up position. If you wish to use the alarm function for high levels of O2, for example an alarm at 23%, the automatic calibration does also need to be deactivated. -

Page 12: General Description
General Description The sensor is an O2 sensor with display that is used to monitor the O2 levels of a confined space. This unit can be connected to a Central Unit or to an existing Mk9 CO2 System for full functionality. - Page 13 Alarm. Ambient O2 concentration level is under or over the alarm constant sound signal settings. The display on the O2 sensor will show the current O2 level and the information text: “EVACUATE AREA: Very critical O2 level!”. If the O2 level is under 19.5%, evacuate the area.

O2 alarm, should be registered on the “What to do” sign. When the central unit is running properly, the green diode (ON) is ON, and the screen should display the O2 levels of the O2 sensor or sensors that are connected. - Page 28 O2 Values displayed on the Central Unit When the system is running properly, the O2 level measured by each sensor is displayed in % (actual value). The values are displayed on the second line of the display. The first character displayed is the sensor ID and the value is displayed after.
