Warranty Summary
None
The Besam SW300/SW150 swing door operator utilizes a DC motor and gear system for automated door operation. It is designed for surface-mounted applications and comes in two versions: SW300 for fire doors with an adjustable mechanical spring, and SW150 for non-fire doors without a spring.
Opening: Upon receiving a signal, the door opens at an adjustable speed, slowing down before reaching full open position. The open position is motor-held.
Closing: After a set hold-open time, the door closes automatically using spring force and motor, slowing down for latch check before fully closing. The door remains closed by spring power or extended closing torque.
Control: Operation modes are selectable via a control switch (OFF/AUTO/OPEN).
