What it is

Summary

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

This Serene Innovations kit pairs a smoke and CO (carbon monoxide) alarm with a wireless audio transmitter. The transmitter listens for the alarm's sound, including the T3 and T4 patterns and traditional alarm tones, and sends a signal to compatible Central Alert units (CA-360, CA-380, CA-PX, CA-RX). Those units then alert you in their own way, so it suits someone who may not hear a standard alarm, such as when asleep or away from the room. The signal reaches up to 200 feet in open space, and walls will shorten that. The smoke alarm has a sealed 10-year lithium battery, and the backup battery runs at least 7 days. It does nothing on its own for a deaf or hard-of-hearing person, because you also need one of the Central Alert receiving units.
