Sentry 1 Button Remote Transmitter – 403MHz
The SENTRY Fixed-code Binary 1 Button 403MHz Radio Frequency Transmitter is a standard DIP-switch type remote control that facilitates up to 4096 unique codes in the binary code protocol. This product is also equipped with a “split-code” mode of operation, which enables the user to assign multiple devices to the same transmitter. This is useful in applications which involve townhouse complexes where a common code may be set for the gate, while still allowing the user to have user-unique buttons that only work with their specific devices in their specific unit within the complex.
Engineered for ultimate versatility, this single-channel handheld transmitter is a true tri-protocol powerhouse. It seamlessly reads and saves signals using Binary, Trinary, or French protocols. Whether you are operating gate automation motors, garage door openers, or industrial security barriers, this compact device adapts quickly to your existing ecosystem

The SENTRY Learning 4 Button 403MHz Radio Frequency Remote Transmitter is equipped with an internal receiver that has the capability of “learning” or cloning another transmitter’s code when the two transmitters are within proximity of one another and the “learning” method is executed as explained in the product leaflet. This embedded technology means that the user will no longer need to adjust DIP switches on the PCB, cloning of remotes is done by simple button-press sequences and is confirmed to be successfully learned into memory by LED flashing on the transmitter that is receiving the copied code. The method of “learning” the code of one transmitter into another transmitter is simple and takes seconds to accomplish and the learning range of transmitters are intuitive and user-friendly. The Learning 4 Button facilitates the cloning of most of SENTRY’s legacy code protocols such as Binary, Inverted-Trinary, and SMART.
