Natural smoke ventilation operating mechanisms "SIMON RWA Systeme"

Optimal use of a window and its belonging actuator

(PresseBox) (Passau, ) All conventional window design types can be controlled using operating mechanisms that have been time-tested and in use for many years. The following electric motor systems dominate this field:

- Direct openers with rack, spindle or chain drive units
- Scissor drive systems

Depending on the size and weight of the window and its installation position, additional mechanical interlocks are used in combination with these mechanisms in order to maintain the security and weather ability of the window system.

Supporting regulations

- Powered windows, see ZH 1/94 and ZVEI publication "RWA aktuell No. 3"
- Maintenance of electric cable function, see specimen cable system directive (MLAR), which has now come into force in all states in Germany.
