LogiCO2 RCB to transmit alarms to external devices with greater control
The LogiCO2 RCB is a remote connection box that transmits pre-alarms and high alarms to external devices, such as sirens and beacons, and adds delay, manual reset and silence functions.
What this product offers
This accessory is intended for LogiCO2 installations where the system’s local alarm is not enough and external devices, such as a horn/strobe, need to be activated with more controlled logic.
Its real value is that it not only replicates an alarm output, but also incorporates management via relays, selection of pre-alarm or high alarm, delay to avoid unwanted alerts during tests, and latching functions with manual reset.
In hospitality, beverage industry, wineries or technical rooms, this helps to better integrate the safety system with remote signaling or internal emergency protocols.
Key data
Manufacturer’s part number 0472
SKU Install Beer LG011
Main function Transmit alarms to external devices
Relés 2 dry changeover relays
Configurable delay 9,5 segundos
Power supply Via sensor
Important: this RCB does not replace the sensor or the control unit. It is an accessory to extend the activation logic of external devices within the LogiCO2 system.
Main features
-
Two dedicated relays Includes one relay for pre-alarm and another for high alarm, with the possibility of reassignment via DIP switches.
-
Volt-free contact The relays can be configured as dry contact, useful for external integrations.
-
9.5 s delay Helps prevent unwanted calls or activations during system testing.
-
Latching functions It can latch after 9.5 s and require manual reset.
-
Horn/strobe mute Allows the siren/beacon to be silenced during high alarm in certain configurations.
-
DIP-switch configuration Each relay can be independently adjusted for function, activation and normal state.
-
Simple blue RJ45 connection Works on the sensor alarm output cable and towards the external device.
-
Compact design Robust, compact housing, suitable for protected technical installation.

Compatibility and use cases
The RCB is designed as an accessory for LogiCO2 alarm systems and for activating external devices, especially horn/strobe units.
It is suitable for installations where you want to separate remote signaling from the sensor, add delay logic, or require a manual reset after a sustained alarm.
It is especially useful in technical rooms, hospitality venues, breweries, wineries and other installations where an external signal must be managed with more control than a simple direct output.
Installation and considerations before buying
- Install the box in a suitable, mechanically protected location.
- The cover opens by twisting and must be removed to access the mounting point.
- Before purchasing, confirm that you really need external relay logic and not just the horn/strobe connected directly to the system.
- Check whether you need to act on pre-alarm, high alarm, or both, because the configuration is done via DIP switches.
- If the project requires interlocking and manual reset, select an appropriate latch function.
- If you want to avoid unwanted triggering during tests, use the 9.5-second delay option.
- If the external device must remain active under normal conditions or only be activated in alarm, check the position of the relay function DIP switches.
Recommended maintenance and use
For this type of accessory it is advisable to periodically check the RJ45 cabling, the mechanical fastening, the integrity of the cover and the logic selected on the DIP switches, especially after any intervention or expansion of the system.
It is also advisable to perform controlled tests of relay activation and verify that the mute, delay and manual reset functions respond as required by the installation protocol.
Frequently asked questions
¿Para qué sirve exactamente la RCB?
It is used to transmit pre-alarms and alarms to external devices, for example a horn/strobe, adding delay, reset and mute functions.
Does it include independent relays?
Yes. It has two dedicated relays, one for pre‑alarm and one for high alarm, with reconfiguration options.
What delay does it include?
It can apply a 9.5-second delay before activating the relay, useful for avoiding unwanted alerts during tests.
Does it allow manual reset?
Yes. Some functions include latching and require manual reset.
Can the horn/strobe be muted?
Yes. Mute can be enabled by DIP switch for the horn/strobe during high alarm.
What does the kit include?
Includes the RCB box, two 1‑meter CAT5 cables, an RJ45 1‑2 splitter and a sign.
