Smoke and Carbon Monoxide Alarm Inventory and Test Log Template
An alarm inventory prevents expired devices, missing bedrooms, dead backup batteries, failed interconnection, and unexplained chirps from disappearing into the household’s collective memory.
What to know
- An alarm inventory prevents expired devices, missing bedrooms, dead backup batteries, failed interconnection, and unexplained chirps from disappearing into the household’s collective memory.
- Inventory every alarm, test monthly, track replacement age, verify interconnection, and record failures immediately.
Create one record for every smoke alarm, carbon-monoxide alarm, combination alarm, strobe alarm, bed-shaker alert device, and monitored alarm interface.
Test smoke and CO alarms monthly using their test buttons.
Replace smoke alarms after the manufacturer’s service-life limit, commonly 10 years. CO alarm replacement follows the model instructions and end-of-life signal.

Placement review
Smoke alarms should generally be installed:
- Inside every bedroom
- Outside every separate sleeping area
- On every level
Interconnected alarms provide better warning because activation of one can cause all connected units to sound.
CO alarms are generally recommended on every level and outside sleeping areas, installed according to the manufacturer’s instructions.
CO alarms do not replace smoke alarms.
Local codes can require additional locations or hardwired systems.
Monthly test record
| Date | Alarm ID | Test button worked | All interconnected alarms sounded | Battery warning | Fault signal | Action | |---|---|---|---|---|---|---| | | | | | | | |
Use the test button.
Do not test a smoke alarm with flame, burning paper, a candle, cigarette smoke, or unapproved aerosol.
Do not test a CO alarm using vehicle exhaust, a generator, furnace exhaust, or a grill.
Those methods create real hazards and do not reproduce the manufacturer’s controlled test.
Know the sounds
Record the sound pattern for:
- Smoke emergency
- CO emergency
- Low battery
- End of life
- Malfunction
- Interconnection fault
Keep the manual or photographed sound-code chart in the household emergency file.
Battery record
| Alarm ID | Battery installed | Battery date | Replacement due | Low-battery chirp | Battery changed | |---|---|---|---|---|---| | | | | | | |
Replace ordinary batteries according to the alarm manufacturer and local guidance. Test monthly even when a sealed long-life battery is used.
Never remove a sealed battery or defeat a tamper-resistant housing.
Replacement dates
Smoke alarms
Replace at the manufacturer’s stated age, commonly 10 years, or sooner when the alarm fails testing or is recalled.
CO alarms
Service life varies.
Replace when:
- Manufacturer’s age limit is reached
- End-of-life signal sounds
- Unit fails testing
- Unit is damaged
- Recall applies
Do not calculate age from the purchase receipt when the manufacturing date shows the alarm was already older.
Interconnection test
During the approved test:
- Press one alarm’s test button.
- Confirm connected alarms respond as documented.
- Repeat at another alarm where required.
- Check every bedroom and level.
- Confirm every occupant can hear or perceive the signal.
Do not assume hardwired alarms remain interconnected after renovation, replacement, or circuit work.
Accessibility
Record whether a household member needs:
- Strobe
- Lower-frequency sound
- Bed shaker
- Pillow shaker
- Connected alert
- Caregiver notification
Confirm the alarm can be heard or perceived from sleeping rooms.
Nuisance alarms
Do not remove the battery because cooking or steam triggered an alarm.
Use the hush control, improve ventilation, and correct placement according to the installation instructions.
A nuisance alarm requires placement or ventilation correction, not ceremonial disarmament.
Recall check
Search CPSC using manufacturer, model, date code, and serial range.

When an alarm sounds
Smoke alarm
- Leave immediately.
- Follow the fire escape plan.
- Call emergency services from outside.
- Do not re-enter.
CO alarm
- Move everyone into fresh air.
- Call emergency services.
- Do not search the home for the source.
- Do not re-enter until authorities say it is safe.
A CO alarm supplements proper appliance installation and maintenance. It does not make indoor generator or grill operation safe.

Bottom line
Inventory every alarm, test monthly, track replacement age, verify interconnection, and record failures immediately.
The device on the ceiling is easy to ignore because its preferred operating state is silence. The log makes sure silence means “working and waiting,” not “expired sometime during an administration no one remembers fondly.”
