Swing-door drive
Operating instructions
eng
8.3 Push-button for opening request – option
To open the swing door, there is a possible alternative to the
radar sensor, in the form of an opening button or an elbow
push-button. These buttons are located near the swing door,
either inside or outside depending upon requirements.
Actuation of this push-button opens the swing door in ac-
cordance with the setting of the programme switch.
8.4 Spring-operated key switch – option
The spring-operated key switch mounted on the outside
makes it possible to open the swing door from the outside,
even in OFF operation mode and even if the swing door is
closed and locked. This opening requirement is important
for buildings where the swing door is the only entrance.
If an optional spring-operated key switch is operated, the
swing door opens.
The door closes after the set hold-open time.
8.5 Manual release push-button
The manual release push-button is part of a hold-open sys-
tem (fire protection door).
When actuated, the closing operation for the fire-rated door
is initiated immediately.
8.6 RESET push-button
With the RESET push-button, you recommission the swing-
door system after actuation of the manual release push-
button or after closing, using a smoke detection function.
