Remote Control of Ventilation Systems (RCO-V)

Buildings are often too closed for sufficient natural ventilation and therefore provided with mechanical ventilation to refresh the air. In the event of disasters and incidents, the local disaster transmitter calls for the closing of windows and doors. Switching off the ventilation system is often forgotten, and is just as necessary.

There is a solution for this: RCO-V


Look at the risk map of the Netherlands, and you see that the risk is by far the greatest in the Rotterdam region. But also elsewhere ships sail and trains with hazardous substances through densely populated areas, and everywhere in Belgium and the Netherlands there are danger zones near or even in residential areas.

Locked up

Buildings are often too closed for sufficient natural ventilation and therefore provide central mechanical ventilation for air changes. This means that the system sucks in outside air. If there is a toxic cloud outside, that is dangerous. It is therefore important to be able to stop central mechanical ventilation in buildings. However, many installations can only be switched on or off in the buildings themselves, and only by a designated key holder. If you are already thinking about it, the key holder will not go out on the street in a toxic cloud to switch off the ventilation system, or too late. And the first quarter is crucial for toxic clouds.

Widely supported

In cooperation with services from the various safety regions, a system has been developed with which the control room can switch off ventilation systems at the touch of a button. Switching is via the mission critical network of Entropia

This system is called "Remote Control Operation - Ventilation" (RCO-V).

"Unfortunately, safety awareness only arises when people feel the threat," according to the security services. "Evacuation is usually not the best option due to the high rate of movement of a poison or gas cloud, but it is even more important to be able to close the ventilation quickly."

The control room

The system is integrated in the work screens of the control room. When an incident is reported, the operator signs a risk area on the GIS card. The software then asks "Do you want to switch off the underlying ventilation systems?". If the operator ticks "Yes", the systems are switched off. It can not be easier. It is important that this solution is in the software that the control room uses every day. If such a system is separate and only used in the event of disasters, then a central operator only uses it once every few years. That is asking for delays, confusion and mistakes, especially in stress situations such as a toxic cloud.

Switch yourself

RCO-V also offers the owner the possibility to switch, via a protected site. This can be relevant if, for example, there are stench complaints caused by a local container fire or by a roof.



Disabling is done via the ENTROPIA network. This network has been chosen because you can not rely on public or consumer networks in the event of incidents, and other networks will be closed within a few years, such as GPRS and 3G. In addition, Entropia has secure connections with various control rooms. The underlying applications are hosted at two geographic redundant locations outside the region, and the backup is also located at a different location. This ensures that the remote control always works.

RCO-V in short:



• Meets more than 100 requirements and wishes;
• existing techniques based on P2000 (paging), Tone Frequent or GSM were not sufficient;
• Entropia has a license of at least 10 years;
• the BOA-V is already standardized in various safety regions;
• Entropia is ISO 9001, ISO 14001 and VCA ** certified.


• The entire chain has no weak links;
• servers are duplicated;
• Entropia is high reliable, especially when other (public) networks fails
• the monitoring center switches itself;
• the system automatically tests itself, you know it works.


• Switching is a routine operation for employees;
• the control room signs a 'risk area' on a map
