Signature Series Weather Alert 418 MHz Transmitter (WT-SS)

Summary

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

This transmitter acts as a bridge between a standard weather alert radio and the Silent Call Signature Series wireless alerting system, converting the radio's audio alert signal into a wireless trigger that activates compatible Signature Series receivers — which can flash lights, vibrate a bed shaker, or trigger other visual/tactile alerts. It's designed for people who are deaf or hard of hearing and rely on visual or tactile notifications rather than sound to become aware of emergency weather broadcasts. This is not a standalone product — it requires both a compatible weather alert radio (not included) and at least one Silent Call Signature Series 418 MHz receiver (also not included) to actually deliver an alert. This is a one-way transmitter only; it signals that an alert is happening but doesn't display or relay the specific weather message, so users still need another way to get the actual warning details.

What Setup Looks Like

• Out of the box
  Install the two included AA batteries into the transmitter.
• With a guide
  
  1. Plug the transmitter into the audio output jack of your compatible weather alert radio using the appropriate cable connection.
  2. Confirm your Silent Call Signature Series 418 MHz receivers are paired and within range to receive the transmitted signal.
  3. Test the system by triggering a test alert on the weather radio and verifying receivers activate — expect 15–30 minutes total setup. See manufacturer support resources for detailed instructions.
