How the ASSA ABLOY SW300, SW150 work

The swing door operators ASSA ABLOY SW300,SW150 use a DC motor and a gear-reduction system
to drive an arm system which opens the door. Closing power is provided by a motor and a closing
spring (not for ASSA ABLOY SW150). A highly sophisticated electronic control unit uses a motor
encoder and a microprocessor to control the door's movement.
To activate the operator you can use a manual activator (elbow switch) or an automatic activator
(radar device). It is also possible – where local standards allow – to activate the operator by just
pushing the door, if Push & Go is selected.
After the door has been activated it will open and stay open for a specified Hold Open Time (HOT).
When the HOT has elapsed the door will close.
The ASSA ABLOY SW300, SW150 can be set in three or four different modes, depending on programme
selector type, see table below.
In fully manual use (or in case of a power failure) the ASSA ABLOY SW300 acts as a normal door
closer. The ASSA ABLOY SW150 has no spring and if open at power failure, door will not close.
