Price is what the vendor listed when last checked. Confirm it with the vendor before buying.

Setup with instructions The hardware is simple, but the system only works when the transmitter, a compatible weather radio, and a Signature Series receiver are all connected correctly. A family member can do this with the manual in about half an hour. Testing the alert end to end is the step that matters most, so guided setup fits.

What it is

Summary

AI-generated from vendor-published content · October 1, 2026

This transmitter connects to a compatible weather alert radio and sends a wireless signal to a Silent Call Signature Series 418 MHz receiver whenever a severe weather alert goes out. That lets someone who can't hear the radio's alarm still get a warning through the receiver's own alert. It runs on two AA batteries, which come in the box, and connects with a plug-in cable. This is one piece of a system: it does nothing on its own, so you'll need both the weather alert radio and a Signature Series receiver.
