The Allstar 109031 3 Door OCS Classic Remote (model 8833TC-OCS-288RF) is a three-button handheld transmitter designed for legacy Allstar OCS Classic systems operating on 288 MHz. Built for multi-door control in commercial or industrial environments, this three-channel transmitter allows you to operate up to three separate overhead doors, gate operators, or access points that use compatible OCS Classic 288 MHz receivers. It’s an ideal replacement remote or spare for facilities using Allstar OCS Classic hardware, helping restore reliable day-to-day access control without changing existing receivers or wiring.
Functionally, the 8833TC-OCS-288RF uses OCS Classic trinary code-switch programming: you match the internal code switches to the settings in the OCS Classic receiver (or to a working transmitter) and assign each button to the intended door/channel. Because it is purpose-built for the OCS Classic 288 MHz platform, it is not cross-compatible with Allstar/Allister 318 MHz products, MVP/Pulsar series, or other brands’ radio systems. Typical applications include commercial overhead doors, warehouse and industrial bays, and gated entries using OCS Classic 288 MHz receivers. For safe operation, program and test the transmitter at the receiver location, keep clear of moving doors and gates, and ensure only authorized users have access. Confirm your receiver’s labeling for “OCS Classic” and 288 MHz before purchase to ensure proper compatibility with part number 109031.
