The Allstar 108817 Three Button Classic Remote 8833T is a three-channel handheld transmitter designed to operate compatible Allstar/Allister/All‑O‑Matic garage door openers, gate operators, and access control receivers that use the Allstar “Classic” fixed-code radio system on 318 MHz. Each button controls an independent channel, allowing a single remote to command up to three separate doors or gates—ideal as a replacement remote for legacy residential or commercial installations using Allstar Classic receivers.
Operating on 318 MHz with fixed-code trinary DIP-switch programming, the 8833T is set up by opening the transmitter and matching its internal code switches to the code switches in the compatible Allstar/Allister receiver or operator; repeat the process as needed when assigning additional buttons to other receivers. This model is intended only for Allstar/Allister Classic 318 MHz code-switch systems and is not compatible with Allstar/Linear MVP, QuickCode, or MegaCode rolling-code products, nor with 300 MHz Multi-Code or other brands/frequencies. For safe use, ensure the connected door or gate operator has required entrapment protection and test proper reversal/stop functions after programming; keep remote controls out of reach of children.
