What this duplicator is for

The Ruth's sister 433 MHz RF remote duplicator copies the signal from an existing transmitter into its two channels. It is aimed at owners of electric gates, garage doors, retractable doors, curtains or similar 433 MHz equipment who need a spare or replacement handset without re-pairing the receiver.

Behaviour during repeated use

The copier uses one-key smart-copying with ultra-small data-code error and copy oscillation resistance to maintain fidelity across many duplication cycles. Each press sends the stored code at 433 MHz, so the remote behaves like the original transmitter for everyday operation of gates, doors, lighting or heating systems.

Limits of the 433 MHz RF link

The device operates on a single 433 MHz channel and supports CAME TOP series plus most other fixed-code remotes, but it cannot clone rolling-code or encrypted transmitters. Range and reliability depend on the receiver's antenna placement, local interference and battery condition in the duplicator.

Questions about this item

Does the 433 MHz transmitter draw enough power to heat up during all-day operation?

The duplicator is a low-power RF remote that only transmits briefly when a button is pressed, so it does not generate noticeable heat during continuous standby.

What existing remote must I already own for the one-key smart-copying to work?

You need a working CAME TOP series remote or another compatible 433 MHz fixed-code handset to clone onto the duplicator.

Will the duplicator interfere with my older 432 MHz garage receiver?

The unit operates at 433 MHz, so it will not directly trigger a 432 MHz receiver; both frequencies must match for reliable operation.
