Additional LogiCO2 Mk9 O2 sensor kit with siren and wiring

What this product offers

This kit is designed to extend an existing LogiCO2 system without having to install a complete new setup from scratch. Its function is to add an extra oxygen sensor with its own local signaling.

Its main advantage is that it comes preconfigured as an additional sensor, with ID2 address and power taken from the existing system. This simplifies expansion when the installation needs to monitor a second area.

At Install Beer, as official distributors in Europe and providers of installation and maintenance services, this type of kit is particularly suitable for extensions, safety upgrades, and evolutionary maintenance of installations that are already in operation.

Key data

Main features

• Complete expansion kit Includes O2 Mk9 sensor with display, siren/beacon, cables, connectors and signage.
• Plug-and-play format Supplied as an add-on kit to expand an already operating LogiCO2 system.
• Sensor preset to ID2 The manufacturer supplies it configured as an additional sensor with address ID2.
• Powered from the existing system Does not require its own separate power supply if the system is correctly sized.
• Optical O2 measurement The sensor uses an FB‑optical principle and measures oxygen concentration between 0 and 25%.
• Automatic self-calibration The sensor performs self-calibration at regular intervals under normal conditions.
• Backlit display Shows current O2 concentration and operating time in hours.
• Expandable up to 8 sensors The system can be expanded to up to eight connected sensors.

Compatibility and use cases

This kit is intended to add one more sensor to an existing LogiCO2 O2 safety system. It is especially useful when the installation grows or when a second area appears that also needs to be monitored.

It is suitable for plant rooms, cold rooms, areas with a risk of oxygen‑deficient atmosphere, nitrogen installations, and other environments where a single detection unit does not cover the entire risk area.

The documentation itself states that the central unit must be adjusted to the new total number of connected sensors.

Installation and considerations before buying

• The sensor must be installed at breathing height, between 150 and 180 cm from the floor.
• The siren/beacon must be mounted above the sensor, approximately 2–2.4 m from the floor and visible from any entrance.
• The central unit must be located outside the monitored area, in a visible and accessible point.
• Before purchasing, confirm that your existing system can accept an additional sensor and that the central unit can be reconfigured for the new number of sensors.
• Also verify that the system’s electrical sizing allows for expansion with this add‑on kit.
• If the system only has mechanical ventilation, the manual states that the room must have a sensor.

Recommended maintenance and use

The O2 Mk9 sensor performs automatic self-calibration at regular intervals, which reduces the need for manual calibration in a normal environment.

Even so, since this is a safety product, it is advisable to carry out periodic functional checks and, after installation, verify that the new sensor appears correctly on the control unit and that local signalling responds as it should.
