Smoke and heat exhaust ventilation (NSHEV / RWA)

In a building fire within stairwells, atriums, or public lobbies, toxic smoke and hot gases pose the immediate threat to life. A certified smoke and heat exhaust ventilator (NSHEV) according to EN 12101-2 is engineered to drive open facade or roof windows in under 60 seconds, venting toxic fumes upward and keeping evacuation routes clear.

Autowin provides complete certified packages comprising high-torque chain actuators and central control panels equipped with integral battery backup per EN 12101-10. Systems are tested and certified for temperature class B300 (300 °C operation for at least 30 minutes) and operate independently during total mains power failure.

Natural comfort cooling and automated night purging

The same actuators that safeguard human life during fire emergencies serve daily building efficiency through demand-controlled natural ventilation. By interfacing actuators with building management systems (BMS, KNX, or BACnet via WindowMaster MotorLink®), excess heat and stale CO2 are expelled quietly.

During summer months, automated night purging activates: windows open during cool nighttime hours to flush and cool the building mass, significantly lowering daytime air-conditioning energy demands while integrated weather sensors close windows at the first detection of rain.

QUESTIONS & ANSWERS

Technical inquiries for architects and structural engineers

Which European standards must a window for smoke ventilation comply with?

A smoke ventilation window must be tested and CE-certified as an integral unit (frame, sash, hinges, and actuator) according to EN 12101-2. Autowin systems are certified for Class B300 (300 °C for 30 minutes) together with Amawood timber windows as well as major aluminum systems (Schüco, Sapa, Wicona).

What occurs if mains power fails during a building fire?

The WCC 104 control panel incorporates emergency battery backup and charging per EN 12101-10, providing at least 72 hours of full operational standby and ensuring window actuators open instantly upon alarm.

Can the same actuators be used for both smoke ventilation and daily cooling?

Yes. Using WindowMaster MotorLink® technology, the actuator operates at whisper-quiet speeds during daily comfort ventilation and night cooling, while automatically switching to full speed and maximum thrust upon receiving a fire alarm trigger.

How does Autowin interface with central building automation (BMS/KNX)?

Our control panels feature standard bus interfaces for KNX, BACnet, and Modbus, as well as potential-free relay contacts for direct connection to fire alarm panels and building management systems.
