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.
