The Allstar 107478 1 Door OCS Receiver in Oil Tight (JIC) Case, model 831RJ, is a commercial/industrial radio receiver designed to add remote Open/Close/Stop control to a single overhead door, rolling steel door, or gate operator that uses an O/C/S control scheme. Built for busy warehouses, factories, and service bays, it interfaces between Allstar transmitters and the operator’s O/C/S terminals so users can command the operator from a distance with compatible remotes. The oil‑tight JIC‑style enclosure helps protect the electronics from dust, moisture, and shop contaminants common in machine‑tool and industrial environments, making it a dependable replacement part or field upgrade for Allstar and Allister commercial door systems.
As an OCS receiver, the 831RJ provides dedicated Open, Close, and Stop functions for a single door, integrating into the operator’s low‑voltage control circuit and mounting near the head unit for straightforward wiring and service access. Programming is performed to match compatible Allstar radio controls, and installation requires connecting the receiver’s outputs to the operator’s O/C/S inputs and supplying the appropriate control power as specified by the door/gate operator and the receiver’s manual. For safety and code compliance, ensure entrapment protection is functional and follow UL 325 and local standards when adding radio control to commercial operators. Always verify transmitter compatibility, code format, and frequency against your existing Allstar system before purchase or installation.
