The Marantec 75424 External Plug-in Receiver Kit (RCP02) is a universal, add-on radio receiver designed to let you operate a wide range of garage door openers and gate operators with Marantec Digital 315 MHz remotes. Ideal as a replacement or upgrade when the original radio system is lost, obsolete, or incompatible, this plug-in receiver connects to the opener’s wall-control inputs using simple two-wire connections and powers from a nearby household outlet. Once installed, you can program compatible Marantec handheld transmitters to open and close the door, making it a practical solution for standardizing controls across mixed brands in residential or light commercial applications.
Operating on Marantec Digital 315 MHz radio technology, the RCP02 is commonly used with Marantec M3-series remotes and other Marantec 315 MHz transmitters. The receiver provides dry-contact output(s) that tie into the operator’s push-button terminals, so it works with most major opener brands that accept a momentary contact input. Setup is straightforward: mount the receiver near the operator for best antenna reception, plug it into an outlet, attach the low-voltage leads to the control terminals, and use the receiver’s learn button to program the included compatible transmitter. For safety and reliability, install the unit indoors or in a protected location away from moving parts, ensure the antenna is unobstructed, and verify the opener’s control circuit supports external dry-contact activation.
