In addition to the SHE safety functions,
electromechanically actuated smoke extraction
systems offer the following additional functions:
the same system can also be used for “daily
ventilation”. Various vent switches are available
for operation. Any electromechanical driven
window can therefore be opened and closed as
wide as required.

1. Control switch “OPEN / STOP / CLOSE”
After the OPEN or CLOSE switch has been
briefly operated, the window moves
automatically to the end position. If STOP has
been pressed in the meantime, the window
stops moving.

2. Control switch “OPEN / CLOSE” (e.g. keyoperated)
After this switch is briefly pressed, the windows
move to the open or closed end position.

3. Control switch with “OPEN” indicator
“OPEN / STOP / CLOSE” function with
integrated “Open” LED display. This illuminates
as soon as the open button has been pressed.
