摘要:
A portable barrier retraction device having a drive motor with an addressable drive motor control. The drive motor control is capable of being connected in a serial arrangement with one or more other addressable drive motor controls. The drive motor is in rotational communication with at least one retraction assembly configured to retract or deploy a line in response to rotation of the drive motor. The line is configured to retract or deploy a barrier. The drive motor provides selective rotation in response to an addressed signal from a controller. In addition, retraction systems employing portable retraction devices and methods for assembling the retraction systems are also disclosed.
