The Allstar 107483 1 Door OCS Stationary Transmitter (model 831T) is a fixed-location, three-button radio control designed to operate a single overhead door, gate, or barrier with dedicated Open, Close, and Stop commands. Intended for commercial and industrial applications such as guard stations, shipping offices, or loading docks, this OCS transmitter provides a convenient wireless alternative to a wired wall station and serves as a direct replacement for compatible Allstar/Allister/Linear systems. Its discrete O/C/S functions allow attendants to run one operator from a desk or wall-mounted location while maintaining clear line-of-sight to the doorway or gate.
The 831T is part of the Allstar Classic family and is commonly used with compatible Allstar receivers and operators that accept O/C/S radio commands. Programming typically involves matching the transmitter’s fixed-code trinary DIP-switch settings to the receiver, then verifying Open, Close, and Stop response at the intended mounting location. Use indoors at a supervised post to ensure safe operation, and follow operator and local safety standards (including UL 325) so the control is only used when the threshold is visible and properly protected. This unit is ideal for replacements and upgrades where a reliable, stationary O/C/S transmitter is required for a single door or gate on Allstar/Allister/Linear radio control systems.
