Setup with instructions Someone comfortable with basic home wiring can follow the manufacturer's instructions and get this working in about half an hour, so guided setup fits. It is not self-serve because it connects to household wiring and the breaker has to be turned off first. If you are not comfortable working with house wiring, hire a licensed electrician to install it.

What it is

Summary

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

This alarm detects both smoke and carbon monoxide, and it speaks out which one it senses, saying "Fire!" or "Warning! Carbon Monoxide." That spoken message helps someone who can't see a display or tell the danger from a beeping pattern know what to do right away. It links to other compatible hardwired Kidde alarms, so when one sounds, every linked alarm in the home sounds too. It runs on your home's wiring, with two AA batteries as backup in a power outage. It also uses sensing designed to cut down false alarms from cooking. Because it is hardwired, it needs to be connected to household wiring, which means it replaces an existing hardwired alarm or goes in at a new wiring point.

What setup looks like

  • With a guide
    1. Turn off power to the alarm's circuit at the breaker, then take down the old alarm if one is there.
    2. Attach the included mounting bracket, connect the alarm to the house wiring plug, and snap the alarm onto the bracket.
    3. Put in the two AA backup batteries, turn the power back on, and press the test button to hear the voice alert. Plan on about 30 minutes per alarm.
    4. If you want several alarms to sound together, connect them with the interconnect wire and test them as a group.
