LogiCO2 traffic light for CO2 safety systems

What this product offers

This product is intended as a visual signaling element for LogiCO2 safety systems. Its function is to make the system status highly visible within the installation itself.

The manufacturer proposes it as a spare part for older Mk4 and Mk7 systems, although they also state it is compatible with Mk9 and Mk90 systems. For the latter, LogiCO2 recommends as an alternative the Horn/Strobe LED amber glass Add-on KIT.

It is a simple and very visual solution for areas where it is important that the system status can be understood from a distance without relying only on the central unit or the sensor.

Key data

Main features

• Immediate visual signaling Lets you see at a glance whether the sensor is operating or if there is an active alarm.
• Clear color logic Solid green for normal operation, flashing yellow for level 1 alarm, and flashing red for level 2 alarm.
• Compatible with several systems The manufacturer considers it a spare part for Mk4 and Mk7, and also compatible with Mk9 and Mk90.
• 24 V DC operation It integrates with the usual electrical architecture of the LogiCO2 system.
• 3‑segment LED tower Compact, highly recognizable visual solution for technical installations.
• Pre‑wired cable The package includes a 1‑meter Cat5 cable with RJ45 connector.
• Wide temperature range The official page states operation between -20 °C and 70 °C.
• Use as spare or expansion Especially useful for maintaining existing systems or replacing visual signaling devices.

Compatibility and use cases

This product mainly makes sense as a spare part for LogiCO2 Mk4 and Mk7 systems, as stated by the manufacturer.

It can also be used in Mk9 and Mk90 systems, although the brand itself recommends the Horn/Strobe LED amber glass Add-on KIT in those cases.

It is especially suitable for installations where long‑distance visual signaling is important: technical rooms, wineries, breweries, hospitality, and other environments with existing LogiCO2 systems.

Installation and considerations before buying

• Before purchasing, confirm whether your system is Mk4, Mk7, Mk9 or Mk90.
• If the system is Mk9 or Mk90, consider whether you prefer to follow the manufacturer’s recommendation and use the Horn/Strobe LED amber glass Add-on KIT.
• Check the available space for a tower with Ø 52 mm and 358 mm height.
• Check the 24V DC power supply and the integration with the existing system.
• If this is a replacement, confirm the cable length and RJ45 connector required in your installation.

Recommended maintenance and use

As this is a visual signaling device, it is advisable to periodically check light visibility, the condition of the pre‑wired cable, and the correct response of each color according to system status.

For replacements or expansions, it is advisable to check that the system’s visual logic matches the configuration expected by the end user.
