Krown WR300TX Weather Alert 300 Transmitter

Summary

AI-generated from vendor-published content · April 26, 2026

This transmitter connects to a standard weather alert radio and converts its audio alarm into a wireless signal that triggers compatible Krown receivers around your home. It's designed for people who are deaf or hard of hearing and wouldn't otherwise hear a weather alert siren — the transmitter bridges the gap between a standard audio-based emergency system and visual or tactile alerting devices. The transmitter itself is just one piece: you'll also need a compatible Krown receiver (such as the KA300 Alarm Monitor) to actually produce the visual flash or bed shaker output, and those are sold separately. This only works with Krown's own receiver ecosystem, so it won't integrate with other alerting systems you may already own.

What Setup Looks Like

• Out of the box
  Plug the included cord from the transmitter into the audio output or alert jack on your weather alert radio — the transmitter activates automatically when the radio sounds an alarm.
• With a guide
  
  1. Pair the transmitter with your Krown KA300 or compatible receiver following the receiver's pairing instructions.
  2. Test the full chain: trigger a test alert on the weather radio and confirm the receiver responds with its visual or tactile alert (allow 15–30 minutes for setup and testing).
  3. See manufacturer support resources for detailed instructions.
