Round white ceiling-mounted smoke detector with a built-in wireless transmitter

Medallion™ Series Smoke Detector with Transmitter, SD4-MC (US)

by Silent Call Communications

$172.04

Setup with instructions The detector itself installs straightforwardly with a battery and wall mount, but it must be paired with a compatible Medallion Series receiver to provide any alert. Pairing and testing requires consulting the manual, placing receivers strategically, and verifying coverage — achievable by a motivated user or family member with documentation, but not truly self-serve out of the box.

What it is

Summary

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

This smoke detector senses smoke via a photocell and wirelessly transmits an alert signal to Medallion Series receivers, which can trigger flashing lights or bed shakers instead of (or in addition to) an audible alarm. It's designed for people who are deaf or hard of hearing and may not reliably hear a standard smoke alarm, particularly during sleep. This is not a standalone solution — it requires at least one compatible Medallion Series receiver (sold separately) to actually alert you. Battery-powered with a long-life 3V lithium cell, it installs in any room, but you'll need to budget for and plan the receiver placement throughout your home to get full coverage.
