O2 Sensor Kit Mk9 Quick Guide

Nitrogen Generators Safety Note

⚠️ 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.

Calibration

The LogiCO2 O2 sensor has an automatic self-calibration function activated as standard, and no manual calibrations should be needed in normal conditions. ✔️

Installation Height

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.

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.

Diagram shows a wall with an O2 sensor mounted at approximately 150-180 cm (5-6 feet) from the floor. A horn/strobe is mounted above it at approximately 2-2.4 m (80-96 inches) from the floor. A warning symbol ⚠️ is also depicted near the sensor.

Installation Locations

Corridors

In areas where Nitrogen or mixed gas is stored at the end of a corridor, it is paramount to place an extra Horn Strobe at the entrance of the corridor. This provides an early warning in case of oxygen depletion. ?

Diagram illustrates a corridor with gas cylinders stored at the far end. A horn/strobe ? is shown at the entrance of the corridor.

Lower Floor/Basement

In areas where Nitrogen or mixed gas is stored or distributed in Below Grade locations such as Lower Floors and Basements, it is essential to have Horn Strobes before the entrance to the area. ?

Diagram shows a basement area with gas cylinders. A horn/strobe ? is depicted before the entrance to the basement.

Enclosed Spaces

In enclosed spaces, Horn Strobes must be placed outside of each entrance. ?

Diagram shows an enclosed room with multiple entrances. Horn strobes ? are shown mounted outside each doorway.

System Installation

Diagram depicts an office environment labeled "MANAGER OFFICE". It shows a Central Unit, an O2 Alarm Sensor, and a CO2 Alarm Sensor connected within the room.

Installing an O2-kit to an existing LogiCO2 Mk9 CO2 Safety System

Since you are adding an additional sensor to the system, you need to set the correct ID-settings for the sensors and the central unit. This is done using the dip switches.

The O2 sensor in the kit is set to ID2 as standard. If you only have one CO2 sensor connected in the system, you only need to change a dip switch in the central unit. Unscrew the screws and remove the lid of the central unit. Then put dip 1 in the ON position.

If you have 2 or more sensors already connected in the alarm system, please check the User's manual.

Installation Schematics

Schematic diagram illustrating system connections. It shows an O2 Sensor Mk9 and a CO2 Sensor Mk9 connected via cables (lengths indicated: 5m, 10m) to Connectors. These connect to a Power Supply (1.5m cable) and optionally to a Relay RCB (1m cable) or an SMB & Shut off valve (1m cable). The Power Supply and Connectors also link to a Central Unit Mk9 (5m cable). Remote Horn/Strobes are connected to the Central Unit Mk9 (1m cables). Icons for Ventilation ?️ and Fire Alarm ? are shown, implying system integration.

Components shown:

Connection lengths indicated: 1m, 1.5m, 5m, 10m.
