The Transmitter Solutions Stand Alone 85E-4 is an exterior, four-channel receiver designed to add wireless control to gate operators, garage door openers, barrier arms, doors, and other access control equipment. Operating on the 433 MHz band, this universal-style receiver learns compatible Transmitter Solutions 433 MHz transmitters and provides four independent outputs so one unit can control multiple devices or functions in residential or commercial applications. As a stand-alone design, it stores transmitter codes internally and interfaces to existing operators through relay contacts, making it a practical upgrade or replacement part for expanding remote capability without replacing the main controller.
Built for outdoor installation, the 85E-4 is housed for exterior use and is intended to mount near the operator for optimal antenna placement and reliable range. Each channel provides a separate dry-contact interface that connects to the control inputs on most gate and door operators. Programming is performed at the receiver using onboard learn controls and status indication, allowing quick enrollment of transmitters and assignment to specific channels. This model operates at 433 MHz and is intended for use only with manufacturer-specified Transmitter Solutions 433 MHz remotes. For best performance and safety, power the receiver with the low-voltage supply recommended by the manufacturer, wire relay outputs to the appropriate control terminals, route the antenna away from metal obstructions, and verify compliance with local codes and required entrapment protection devices before placing the system into service.
