The document describes the Besam Low Energy Swing Door Operator SW100, an automatic door system designed for safety and compliance with industry standards.
Function Description
The SW100 is a low-energy swing door operator that utilizes a DC motor and a gear-reduction system to drive an arm system, opening the door. Closing power is provided by both the motor and a clock spring. An electronic control unit, equipped with a motor encoder and a microprocessor, precisely controls the door's movement.
The operator can be configured in two main variations to meet low-energy standards:
- Push Plate Activation: The door is activated by push plates and can also be used as a manual door.
- Push-to-Activate Mode: In this mode, the door is manually pushed (or pulled) approximately 5 degrees, after which it automatically opens to its full open position.
Optional overhead presence devices can be provided for an extra layer of protection, though these are not required by current ANSI A156.19 codes.
Opening Operation:
Upon receiving an opening signal, the door opens at an operator-adjusted speed. Before reaching the fully open back check position, it automatically slows to a low speed. The motor stops when the selected door opening angle is achieved, and the open position is held by the motor.
If an obstruction is encountered during opening, the door will either stall or stop, a behavior selectable via a DIP switch.
- Stalling: The door will continue attempting to open throughout the hold-open time.
- Stopping: The door will close after 2 seconds, even if the hold-open time has not expired.
Closing Operation:
Once the hold-open time elapses, the operator automatically closes the door using a combination of spring force and the motor. The door slows to a low speed at latch check before reaching the fully closed position. The door is then kept closed by spring power or extended closing force from the motor.

Usage Features
The SW100 is designed for ease of use and safety.
- Activation: Can be activated via push plates or by manually pushing/pulling the door a few degrees.
- Smooth Operation: Doors open and close at a slow, smooth pace (4 or more seconds) and stop without impact.
- Hold-Open Time: The door remains fully open for a minimum of 5 seconds before closing.
- Control Switches: The operator can be equipped with flush-mounted control switches in the end plates, including a standard Power On/Off switch and an optional On/Off/Hold Open switch.
- Signage: Appropriate "AUTOMATIC CAUTION DOOR" and "LOW ENERGY POWER OPERATED DOOR" decals are applied to both sides of the door, along with "ACTIVATE SWITCH TO OPERATE," "PULL TO OPERATE," and "PUSH TO OPERATE" decals as needed.
Maintenance Features
Regular maintenance is crucial for the continued safe and compliant operation of the SW100.
- Daily Safety Checklist: Users are required to perform daily checks, especially after any power loss, to ensure:
- Smooth opening and closing without impact.
- Correct hold-open time (minimum 5 seconds).
- Clean floor area free of obstructions.
- Good overall door condition and presence of appropriate signage.
- Professional Service: If the door fails any daily safety checks or malfunctions, users are instructed not to attempt repairs or adjustments. Instead, they must discontinue door operation, secure it safely, and call a qualified Besam service technician.
- Annual Inspection: The door should be inspected at least annually by an AAADM certified inspector.
- Planned Maintenance Agreements: Besam distributors offer Planned Maintenance Agreements, which include regular inspections, cleaning, lubrication, adjustments, and replacement of worn components. The frequency of these visits depends on factors like traffic and climate.
- Components for Maintenance: The manual lists several components that typically require periodic maintenance, including gaskets and seals, glass protection bars, moldings and thresholds, pivots, door control operations, door frames, opening and closing speeds, sensor function, and guide rails.
- Warranty: Besam US Inc. provides a 1-year limited warranty on products and parts manufactured by Besam and its affiliates, covering defects in material and workmanship from the date of shipment.
