The Firefly 433TSD22K 10 Switch 433 MHz Long Range Remote is a handheld wireless transmitter designed to control up to ten independent functions on compatible Firefly 433 MHz receivers. Each dedicated button provides a discrete command, enabling multi-channel operation for applications such as lighting zones, pumps, fans, winches, and general-purpose relay activation in residential, commercial, and mobile/RV environments. Used as a primary controller or as a replacement remote, it offers convenient point-and-click operation for on/off or momentary actions depending on how the paired receiver is configured.
Operating in the 433 MHz ISM band, this long-range remote is intended for use with Firefly-branded receivers that share the same frequency and protocol; cross-compatibility with other brands is not guaranteed. Setup typically involves pairing the transmitter to a receiver via learn-mode or address matching per the receiver’s documentation, with no wiring required for the handheld unit. Actual communication distance depends on installation factors such as receiver antenna placement, orientation, and local RF conditions. For safe and reliable use, follow regional RF regulations, keep the device dry and within the environmental limits specified by the system manufacturer, and replace the internal battery as needed. This is not a life-safety device and should be used only to control low-voltage automation systems that are appropriate for remote operation.
