The Keystone Heddolf ER294-1K Long Range Receiver is an external radio receiver engineered to add or restore remote-control capability to gate operators and garage door openers. Designed for extended operating distance and dependable signal reception, it integrates with most operators that accept a standard control input, making it a practical replacement part or an upgrade for residential and commercial applications. The ER294-1K pairs with compatible Heddolf 294-series transmitters to provide a responsive, single-channel trigger for open/close or access control functions, helping improve range where built-in receivers are limited or when cross-brand compatibility is needed.
Use the ER294-1K to retrofit older systems, standardize mixed equipment, or extend remote coverage on entry gates, parking access points, and overhead doors. Installation typically involves wiring the receiver to the operator’s control input and connecting power from the operator’s accessory terminals, then enrolling compatible Heddolf transmitters per the unit’s learn/program procedure. For best performance, mount the unit and antenna in a location with clear signal paths. Follow the operator and receiver manuals for wiring, programming, and safety practices, and ensure setup is performed by a qualified installer to comply with local codes and site requirements.
