Description
Control access to your building, gate, or secure area from up to 400 feet away without rolling down your window or stopping at a reader — the Viking LRT-4 is a 4-button long-range wireless transmitter that works with the Viking LRR-4 receiver to deliver RFID-based remote access control.
The LRT-4 uses 433 MHz radio to transmit secure coded signals up to 400 feet to the LRR-4 receiver. Each of the four buttons triggers a separate Wiegand output on the receiver — giving you independent control of up to four different functions from a single key fob. A red LED indicator confirms button presses and provides battery level feedback, so you know when to replace the battery before it fails unexpectedly. Advanced digital encryption prevents signal cloning and unauthorized duplication. The compact, durable fob design is built for daily use in vehicle-based access scenarios.
Our Expert Take: The LRT-4 is the transmitter half of Viking's long-range RFID solution — pair it with the LRR-4 receiver for a complete 400-foot wireless access system. It's ideal for gated driveways, parking facilities, and large campuses where getting close enough to tap a card reader is impractical. The 4-button design makes it flexible for multi-function control — open gate, close gate, secondary door, and one additional function from the same fob.
