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 aff ect 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 fi tted 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 fi re.
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 fi re.
8. When household cleaning supplies or similar contaminants are used, the area
should be ventilated.
