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

Setup with instructions The alarm works on its own once it is installed, and the bracket and instructions make mounting simple. Still, it connects to your home's wiring, and linking it with other alarms takes care. A family member who follows the instructions, or an electrician, can finish this in under an hour per alarm, so guided setup fits. It does not need a clinical assessment.

What it is

Summary

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

This alarm detects both smoke and carbon monoxide (CO) in a single unit, so one device covers two household dangers. It speaks its warnings out loud, saying "Fire!", "Warning, Carbon Monoxide!" or "Replace Alarm" at the end of its life, which gives clear information beyond a plain beep. It can be hardwired to other select Kidde alarms so every connected alarm sounds when one goes off, helping alert people in other rooms. It has AA battery backup and parts that keep checking that it is working. The smoke sensor is photoelectric, which is better at catching slow, smoldering fires; fire safety experts advise pairing it with ionization alarms too. Because it is hardwired, it needs to be connected to your home's wiring, so plan on an electrician or someone comfortable with that work.

What setup looks like

  • With a guide
    1. Turn off power at the breaker, then mount the included bracket on the ceiling or wall where you want the alarm.
    2. Connect the alarm to your home's wiring (and to other select Kidde alarms if you want them to sound together), then insert the AA backup batteries.
    3. Restore power and press the test button to confirm the voice alert plays. Allow about 30-60 minutes per alarm. If you are not comfortable with household wiring, hire an electrician.
