When to add or replace hardwired alarms
- Alarms are older than the manufacturer's recommended replacement age
- Alarms chirp even after a new backup battery
- Bedrooms or hallways have no alarm at all
- Alarms do not sound together when one is tested
- You are remodeling, adding a bedroom or selling the home
- The home has gas appliances or an attached garage and lacks carbon monoxide alarms
Interconnected smoke and CO alarms
Interconnected alarms are linked by a wire or a wireless signal so they all sound when any one detects smoke. Combination smoke and carbon monoxide alarms cover both hazards in one device, which simplifies installation in hallways near bedrooms. When replacing hardwired alarms, matching the connector type can sometimes make the swap quick.
For a rental or a home sale, ask the electrician about current alarm requirements for your property type.

Caring for your alarms after installation
Test alarms monthly with the test button, replace backup batteries as the manufacturer recommends, and replace the alarms themselves at the end of their rated life. Keep alarms away from kitchens and bathrooms where steam and cooking cause false alarms.
A date written on each alarm at installation makes it easy to know when they are due for replacement.
Alarms in rentals and home sales
Landlords and sellers often need smoke and carbon monoxide alarms in specific locations. Mention a rental or sale when you call so the electrician can plan the right number of alarms.
Questions about Smoke Detector Wiring
Can battery alarms be replaced with hardwired alarms?
Yes. The electrician runs new wiring to each location, usually through the attic, and connects the alarms so they sound together.
Why does my hardwired alarm keep chirping?
Usually a low backup battery or an alarm at the end of its life. If a new battery does not stop it, the alarm likely needs replacing.
