Standard Swing Door
An internal spring located inside the Operator automatically CLOSES the Swing door. An internal Brake located
inside the Motor allows the Swing door to fully close. The Swing door can be manually opened at any time.
X
Inverse Swing Door
An internal spring located inside the Operator automatically OPENS the Swing door (unless the Swing door has
been locked with a Fail/Secure electric lock). An internal Brake located inside the Motor allows the Swing door
to fully open with a slow, controlled motion.
Inverse Swing Door is suitable for:
X
Escape Routes and/or Rescue Routes
X
Extracting smoke from buildings
X
Extracting heat from buildings
Notice: For Escape Routes, Rescue Routes, Exhausting Smoke or for Heat Applications; National and/or Local
Requirements/Regulations may exist . Please ensure these Requirements/Regulations are fulfilled .
It is recommended to install a FAIL/SAFE electric lock on Swing doors using Inverse Swing Doors. During normal operation, the
FAIL/SAFE lock applies continuous pressure to keep the Swing door in a fully closed position. During a Power Failure, the FAIL/SAFE
lock automatically unlocks, thus allowing the Swing door to fully open.
Do Not install Fail/Secure electric locks on Swing Doors using Inverse Swing Doors. Fail/
Secure electric locks will not allow the Swing door to open during a Power Failure.
