Additional LogiCO2 Power Barrier Kit for CO2 safety system

What this product offers

This module solves a typical problem in large LogiCO2 systems or those with many connected devices: the total current consumption can approach the safe limit of a single power supply or a single power loop. In that scenario, the Power Barrier helps distribute the load without breaking the system’s communication architecture.

Its real function is not to detect gas or trigger alarms by itself, but to act as a power distribution accessory within the LogiCO2 safety system. It allows you to work with multiple power supplies and keep different sections of the system electrically separated.

In installations with multiple sensors, sounders, remote boxes, or accessories, this type of module helps maintain stability during an alarm, prevent voltage drops, and make future expansions cleaner from a technical standpoint.

Key data

Main features

• Allows multiple power supplies The manufacturer states that it can work with up to eight power supplies in the same system.
• Respects per-loop limits Each power supply maintains a 1 A output so as not to exceed power limits in cables and connectors.
• Keeps communication with the central unit Even if the loops are separated in terms of power, the sensors continue to communicate with the central unit.
• Galvanic separation of loops The manufacturer’s example installation shows several power supplies connected and galvanically separated using Power Barriers.
• Status LED indicators It has two green LEDs to verify that both sides are powered.
• Compact form factor It shares the usual physical format of LogiCO2 modules, useful for neat technical installations.
• Accessory for real expansions It makes sense in systems with multiple sensors, sounders, O2, Mk90, remote boxes, or additional safety accessories.
• Integration in LogiCO2 architecture It is designed for the LogiCO2 Safety System, not as a standalone universal module.

Compatibility and use cases

The Power Barrier is designed for the LogiCO2 Safety System ecosystem and makes sense in installations with multiple sensors, multiple sounders, or accessories distributed across different power loops.

The manufacturer’s example installation shows compatibility within the same system with a Mk9 central unit, Mk9 CO2 sensors, CO2 Mk90 sensors, and a Mk9 O2 sensor, all communicating with the central unit while power is distributed across several galvanically separated supplies.

It is especially useful in hospitality projects, wineries, breweries, technical rooms, beverage plants, or light industrial installations where the system has already grown and the combined consumption makes it advisable to split power by loops.

Installation and considerations before buying

• Before buying, calculate the system’s total power consumption under alarm conditions, not just in normal operation.
• The manufacturer itself reminds that one power supply has a 1 A output and provides a peak consumption table to assess whether a Power Barrier is needed.
• Check how many sensors, sounders, RCB boxes, sniffers, safety valves, or other accessories are part of the system.
• Also check whether the project uses multiple power supplies and how the loops are physically distributed.
• If the system is already close to the safe current margin or is going to grow, the Power Barrier leaves the installation better prepared to avoid voltage issues.
• Both green LEDs on the module must be lit to confirm correct power on both sides.
• Since it is a system engineering accessory, it should be integrated into the overall design and not added as an improvised afterthought.

Recommended maintenance and use

The Power Barrier does not require complex operation, but it is advisable to periodically check the power status on both sides of the module, the mechanical mounting, the wiring, and the load distribution after any system expansions.

In practice, every time sensors, sounders, or accessories are added to the LogiCO2 system, it is worth recalculating the consumption and checking that the installation remains within suitable margins. That control is especially important in systems that must remain stable during a real alarm.
