The Transmitter Solutions Stand Alone 85I 433 MHz Interior Two Channel Receiver is an indoor, two-relay radio receiver designed to add remote control capability to gates, garage doors, barrier arms, and other access control equipment. Operating on the 433 MHz band, this stand-alone unit stores transmitter codes directly in the receiver and controls up to two independent outputs, making it a practical replacement or upgrade for residential or commercial applications where a simple, self-contained radio control is required. Its interior enclosure is intended for dry, protected locations and is commonly used to integrate handheld remotes with existing openers, operators, or control boards.
This Stand Alone 85I model typically supports a total memory capacity of up to 85 individual transmitters and pairs with compatible Transmitter Solutions 433 MHz remotes from the same family. Programming is performed at the receiver via onboard controls, allowing installers to add or delete specific remotes or clear the entire memory as needed. The unit provides two separate channels for controlling two devices or functions from the same receiver and connects to the host equipment through standard low-voltage wiring. As an interior receiver, it should be mounted indoors away from moisture and installed per local electrical codes and the manufacturer’s instructions. For best results and security, use only matching Transmitter Solutions 433 MHz transmitters verified to be compatible with this Stand Alone series.
