Mechanical smoke extraction systems MSE
Fresh Air + Powerful Fans
Our expertise in the implementation of complex systems for smoke and heat exhaust ventilation will make your project a success.
The thermal properties of flue gases and fresh air are not always sufficient to ensure safe, reliable smoke extraction from a building. There is the risk of suffocation or smoke inhalation. This issue can be addressed by using fans and smoke extraction ducts. When the function of a smoke and heat exhaust system (SHEV) is achieved with these motor-driven fans, this is defined as mechanical smoke extraction (MSE).
Basics
What components make up an MSE system?
These versatile networks made up of a wide variety of components are where the intelligent solutions from D+H deliver their full performance.
Mechanical smoke extraction systems are usually customised for a property. In other words, they are planned and then manufactured based on the application. This kind of system typically consists of smoke extraction fans, automatic intake air openings, smoke extraction flaps, fire dampers, fire detectors and a control panel such as the CPS-M1-MSE from D+H.
The individual components of the system are combined into one complete system, installed and calibrated. After that, the control panel guarantees fully automated and coordinated operation of the system. In case of fire, the system activates automatically as soon as smoke is detected. The system can also be triggered manually at any time.

The KNX Modbus gateway allows sensors, jet fans and ACB/AdComBus components of the groups and lines to be connected to KNX-based building management systems.
Products
Sophisticated technology for greater safety in case of fire
The following products are needed for control and monitoring a mechanical smoke exhaust system.
Bus-capable window drives (Advanced Communication Bus), operation panels and sensors from D+H are important components of a mechanical smoke extraction system. D+H control panels from the CPS-M series support the Modbus RTU protocol, which means they can transmit status signals of individual components and control signals to the building management system (BMS). Your local D+H contact will be happy to help you in the design, project planning and search for suitable suppliers for purchased parts such as smoke extraction fans, smoke extraction flaps, fire dampers, smoke extraction duct systems or smoke curtains.
Solution application
Property-specific design according to use
D+H helps you plan the ideal smoke and heat exhaust system for your building – guaranteed.
The use of a mechanical smoke extraction system is recommended in particular in multi-storey buildings, interior facilities and underground car parks. Systems for mechanical smoke extraction also provide protection in shopping centres, large-scale industrial buildings, logistics centres, power plants and heating facilities. They increase the likelihood of rescuing people who are still in the building. MSE makes firefighting operations in the building easier for the firefighters and helps protect property as well as prevent operating failures. In daily use, MSE provides general ventilation and extraction and reliably vents the building after a gas leak, such as of CO, NO2 or LPG.

How mechanical smoke extraction works with the CPS-M controller
Our controller provides what no other provider of mechanical smoke and heat exhaust ventilation systems can.
We have developed an outstanding controller for all application areas, such as a mechanical smoke exhaust system. The CPS-M1-MRA is a control panel for controlling systems designed to prevent the spread of smoke, heat and fire – and it can be expanded to meet individual requirements. The CPS-M1-MRA controls and monitors all components and regulates the power supply for the entire system. During everyday use, the CPS-M1-MRA is also suitable for controlling ventilation systems in buildings.
Above all, however, the CPS-M-MRA demonstrates its special capability in complex systems such as a mechanical smoke extraction system. The programming and structure of the CPS-M1-MRA are based on fire scenarios or on relevant directives for the design of ventilation systems. This means, for example, the controller can be used in underground car parks. If sensors detect too much carbon monoxide (CO), nitrogen dioxide (NO2) or liquefied petroleum gas (LPG) in the underground car park, then smoke extraction fans will be started by the CPS-M. The fans can be activated by means of frequency converters, soft starters or directly by contactors (switches).
Your advantage with the CPS-M1-MRA:
- Modular structure of the controller, individualised according to customer requirements
- Additional assemblies can be retrofitted at any time
- Can easily be configured as desired with the D+H SCS software
- Not bound to the software and programmers of other PLC manufacturers
- Supports ACB bus communication based on Modbus RTU
Application area
A clever combination of natural ventilation and mechanical smoke extraction

Savings in electricity consumption and a plus for well-being
Mechanical smoke extraction and natural ventilation in combination - When it comes to new buildings, D+H experts always plan the use of intake air openings for mechanical smoke extraction. And in the case of an existing building, a solution is sought to integrate existing ventilation windows into any new MSE system to be installed. This way, costs for additional intake air openings can be saved.

At No. 1 Old Trafford, DH Mechatronic UK Ltd implemented a solution for mechanical smoke extraction. D+H UK supplied not only the window drives and controllers, but also the fans and smoke extraction flaps for the extraction shafts. The scope of the project includes 2 large CPS-M1-MRA MSE control panels, NSHEV skylights for ventilation of the stairwells, smoke extraction flaps and heat-resistant extractor fans.
