Introduction
Thank you for purchasing our smoke alarm. This smoke alarm conforms with the
UL 217 standard and is designed to detect smoke. Our products are constantly
being improved and expanded.
Visual and Audible Alerts
During an emergency, the unit will alarm at 85 dB within a distance of 3 meters,
and a red LED indicator will flash in sync with the alarm tone.
Battery Operated
A long-life lithium battery sealed inside the alarm ensures a 10-year lifetime in
standby condition.
Silence Mode
Silence your smoke alarm by momentarily pressing the test/silence button when
non-emergency smoke (e.g. steam) causes nuisance alarms. The red indicator
flashes every 5 seconds to remind you that the smoke alarm has been silenced.
Press the test/silence button to exit the silence mode or wait 9 minutes for the
alarm to automatically exit the silence mode.

Installation Positioning NOTE: If a smoke alarm is installed in a kitchen, ensure it has an accessible silence button,
and install it as far away from the stove and sink as possible to avoid false alarms.
1. Prioritize the installation of a smoke alarm in the bedroom and walkways, and
make sure you can hear the alarm from all sleeping areas. In a home with several
bedrooms, install an alarm in every bedroom. If you install only one smoke alarm
in your home, install the alarm near to all bedrooms where possible, and not in a
basement or furnace room.
2. Install an alarm above the stairway and on every floor of the house.
3. Smoke, heat and anything burning will spread horizontally after rising to
the ceiling, so install the alarm in the middle of the ceiling where possible.
Ensure that the alarm is installed at the minimum distance away from corner.
4. If an alarm cannot be installed in the middle of a ceiling, install it at a distance of
20 inches (50 cm) away from the corners of the room.
5. If an alarm is installed onto a wall, a distance of 4-12 inches (10-30 cm) should be
kept below the ceiling.
6. If the length of a room or hall is beyond 30 feet (900 cm), several alarms should
be installed in the same room.
7. When the wall or ceiling is angled, the alarm needs to be installed within 3 feet
(90 cm) of the highest wall or ceiling point (measured horizontally) in the room.

Technical Specications
Power Supply 10-year sealed lithium battery (non-replaceable)
Sensor Type Photoelectric
Safety Standard UL 217
Coverage Area 215–430 sq. ft (20–40 m²)
Operating Temperature 40–100°F (4.4–37.8°C)
Operating Relative Humidity ≤ 85% (non-condensing)
Alarm Loudness ≥ 85 dB at 10 ft (3 m) @ 3.2 ± 0.3 kHz pulsing
alarm
Silence Duration About 9 minutes
NOTES
1. Battery life is calculated on the current ratings in the standby mode with weekly
testings. If its operation mode changes to an alarming condition, the battery life will be
decreased accordingly.
2. The smoke alarm functions between 40 and 100°F (4.4 and 37.8°C). Prolonged exposure
to temperatures outside of this range can reduce battery life and affect accuracy. We do
not recommend operating the device outside of this range.
Maintenance
To keep your smoke alarm in good working order, follow these simple steps:
1. Verify the unit’s alarm sound and indicator are working properly by testing the
unit once a week.
2. As a minimum your smoke alarm should be cleaned once every 3 months:
Remove the unit from the ceiling and clean the alarm cover and vents with your
vacuum cleaner fitted with the soft brush attachment to remove dust and dirt.
3. Never use detergents or other solvents to clean the unit.
4. Avoid spraying air fresheners, hair spray or other aerosols near the alarm.
5. Do not paint the unit. Paint will seal the vents and interfere with the sensor’s
ability to detect fire.
6. Never attempt to disassemble the unit or clean inside. Doing so will void your
warranty.
7. When removed, place the smoke alarm back in its proper location as soon as
possible, to assure continuous protection from fire.
8. When household cleaning supplies or similar contaminants are used, the area
should be ventilated.
Troubleshooting
PROBLEM SOLUTION
Your smoke alarm does not sound
