It is recommended to have at least one smoke
alarm per room, per floor.
As a minimum, smoke alarms should always be
located between sleeping areas and potential
sources of fire, like kitchens, living rooms, and
garages.
Additional alarms should be placed in sleeping
areas.
For best protection, smoke alarms should be
installed in every room in your home, apart from
those listed in section 4.
Where To Install Smoke Detectors
- In windy areas, such as near fans, air conditioners,
or open windows.
- In high humidity areas like bathrooms.
- At the top of an “A” frame ceiling. “Dead air” at the
top may prevent smoke from reaching the alarm in
time to provide an early warning.
- Less than 12 in from the wall when
mounted on the ceiling.
- In insect-infested areas, tiny insects may affect
performance.
- In kitchens, boiler rooms, laundry rooms, or
garages.
- In very dusty or dirty areas, dirt and dust can build
up and impair performance.
- Within 12 in of a light fixture.
- In locations that would make routine testing or
maintenance hazardous (e.g. over a stairwell).
- On poorly insulated walls or ceilings.
- Near objects such as ceiling decorations that might
impede the path of smoke to the alarm.
- Within 5 ft of fluorescent light fixtures.
Test each alarm at least once a week
Always protect your hearing when testing. Press the
test button for two seconds. The alarm will sound a
few short, loud beeps. Upon releasing the button,
the sound will stop. The App will receive a test signal
after ten seconds.
Reset the alarm
If the test does not function properly, reset the Wi-Fi
base.
Repeat the steps above.
Replace or return the alarm if the test does not
function properly after completing these steps.
Cleaning
Clean the smoke alarm at least once a month; gently
vacuum the outside of the smoke alarm using your
household vacuum’s soft brush accessory. Test the
smoke alarm after cleaning. Never use water,
cleaners, or solvents since they may damage the unit.
