AUMULLER Compact Control Unit EMB7300
The AUMULLER EMB7300 is a compact smoke ventilation control unit for 24 V DC window actuators used in smoke and heat exhaust ventilation systems and controlled natural ventilation. It is intended for stairwells, corridors and other small to medium-size building sections where dependable smoke extraction, ventilation control and compact installation dimensions are required.

System Overview And Control Functions
The EMB7300 compact control unit is a central element of a natural smoke and heat exhaust ventilation system. In practical terms, it supplies power and sends control commands to 24 V DC actuators used for smoke exhaust windows and ventilation windows. This makes the unit responsible for one of the most important tasks in a smoke ventilation system: opening designated building elements in order to remove smoke and heat during a fire event.
In addition to emergency smoke extraction, the EMB7300 can also be used for daily ventilation. That combination is especially important in modern buildings, where the same window drives often need to serve both comfort ventilation and life safety functions. As a result, the EMB7300 is not only a smoke ventilation panel, but also a practical building control device that helps combine safety and everyday operation in one compact unit.
From an SEO and technical point of view, this is exactly what designers and installers look for when searching for terms such as smoke ventilation control unit, compact SHEV panel, 24 V smoke exhaust control panel or natural smoke ventilation control system.
Typical Applications And Building Use
The EMB7300 is especially suitable for stairwells, escape routes, residential buildings, office buildings, schools, public buildings and technical zones where local smoke ventilation sections have to be controlled reliably. Its compact construction makes it a strong choice wherever wall space is limited but a professional smoke exhaust solution is still required.
In many projects, compact smoke ventilation control units are selected for staircase pressurization alternatives, smoke exhaust windows at the top of staircases, corridor ventilation sections and other local smoke extraction areas. In such scenarios, the EMB7300 supports a clear and robust fire safety strategy by controlling window opening in response to smoke ventilation signals and ventilation commands.

Operating Logic And Smoke Ventilation Priorities
A smoke ventilation control unit must do more than just power actuators. It has to manage operating priorities between emergency smoke extraction and daily ventilation. In real building use, fire mode must always take priority over standard ventilation commands. That principle is fundamental for smoke and heat exhaust systems, and it is one of the key reasons why dedicated control units such as the EMB7300 are used instead of standard window automation alone.
The EMB7300 is intended to work as a dedicated control point within the SHEV installation, coordinating actuator movement and helping ensure that smoke exhaust windows respond correctly when the system is triggered. This supports safer evacuation, better smoke removal and more reliable behavior of controlled window drives in fire-related scenarios.
For installers and designers, this means the EMB7300 should be understood as a functional smoke ventilation panel rather than only a power supply. Its role in the system is directly linked to smoke exhaust performance, ventilation control logic and correct operation of the connected 24 V DC window actuators.
Accessories And System Expansion
The EMB7300 can be supported by additional accessories and related technical components documented for the EMB series. These include connection and expansion elements used to adapt the control unit to the specific needs of the project, signaling logic and integration requirements.
Based on the EMB7300 documentation set, the available related materials include accessories such as a BMZ connection module, REL65 relay module, 7x PSB plug-in card, forwarding-related solutions and additional acoustic signaling configurations. In practice, these supporting elements help adapt the smoke ventilation control unit to more specific system requirements and installation concepts.
