Ask whether every sleeper can hear and notice the alarm, where units must go to sound together, and how they stay powered over time. Choose interconnected smoke alarms for all bedroom areas and levels plus battery-backup carbon-monoxide detectors near sleeping areas.
Aging in place means staying safely in your own home as needs change with age. That choice raises the stakes for detection because the U.S. Fire Administration reports adults age 65 and older are 2.6 times more likely to die in a home fire than the general population, with risk higher after age 85 older-adult fire safety report.

Will the sound wake the person who needs it?
Standard smoke alarms use about 3,000 Hz, a pitch age-related hearing loss often misses. Studies for the U.S. Fire Administration found a 520-Hz square-wave alarm wakes 92-96% of older adults, hearing-impaired people, children, and heavy sleepers, according to the NFPA 72 update release low-frequency alarm effectiveness release.
Ask for low-frequency sound if hearing is reduced, sleep is deep, or hearing aids come out at night. For hearing or vision impairment, add a strobe light or bed-shaker alarm. The Washington State Fire Marshal recommends these add-ons for older adults with hearing or vision impairment, plus monthly testing.
Where must alarms go to protect sleep areas?
NFPA 72 calls for interconnected smoke alarms inside every bedroom, outside each separate sleeping area, and on every home level including the basement, according to the Fire Engineering report on the standard NFPA smoke alarm placement report. Interconnected means all sound together when one detects smoke. Ask whether the models you are comparing can interconnect across floors and bedrooms.
Walk through the home with that checklist before buying. Count bedrooms, hallways outside sleep areas, living levels, and the basement. Buy enough units to cover each spot, not just one alarm per floor.
How will alarms keep working month after month?
Dead or missing alarms drive most home fire deaths. NFPA safety guidance says test smoke alarms monthly with the test button and replace them after 10 years or when they stop responding.
Ask who will do the monthly test if ladders or high ceilings are a problem. Pick a fixed day, such as the first of the month, and pair it with another task. For carbon monoxide, CDC advises installing battery-operated or battery-backup detectors near every sleeping area and checking them regularly.
- Test all smoke and CO alarms monthly
- Replace smoke alarms at 10 years or at failure
- Keep battery backup in every CO detector
- Plan who helps with hard-to-reach units
Does the CO detector meet the right safety standard?
Carbon monoxide is odorless and colorless and can kill within minutes if exhaust is blocked. Ask whether a residential CO alarm meets UL 2034, and whether a combination smoke-CO unit also meets UL 217.
The Consumer Product Safety Commission warns that tested OKEAH combination units failed to alarm at 400 ppm CO and at set smoke levels CPSC detector failure warning. Check the package or listing for both UL marks before purchase. Do not keep using a unit that has failed a test or passed its replacement date.
Where will the generator run in an outage?
Never run a generator indoors or in a garage. CDC toolkit guidance says generators must run only outdoors more than 20 feet from the home, doors, and windows.
Ask where the 20-foot spot is before storm season, not during it. Pick a dry, open outdoor location and keep a long enough cord to avoid moving it closer. Remind caregivers and visitors that opening a garage door does not make indoor generator use safe.
Frequently Asked Questions
How many smoke alarms does an older adult living alone need?
Plan for inside every bedroom, outside each sleeping area, and on every level including the basement, with all units interconnected.
What helps if hearing aids are removed at night?
Choose a 520-Hz square-wave alarm and add a strobe light or bed-shaker, then test monthly.
When should a smoke or CO alarm be replaced?
Replace smoke alarms after 10 years or when they stop responding to the test button, and check CO detectors regularly with battery backup in place.
