IMPORTANT SAFETY INFORMATION
1.This smoke alarm requires constant 220-240V AC 50Hz mains power supply to operate properly.
Backup 9V DC battery will offer additional protection in the event of power failure. This smoke alarm
WILL NOT work if AC power is not connected or has failed or been interrupted for any reason. AND if
the backup battery is removed, drained or improperly connected, the alarm will not work during a power
failure. DO NOT use any other kind of battery except as specified.
2. The push-to-test button accurately tests all smoke alarm functions. Do not use any other test method.
Test smoke alarm weekly to ensure proper operation.
3. DO NOT cut off AC power supply or remove or disconnect backup battery to quiet unwanted alarms.
This will remove your protection. Open windows or fan the air around smoke alarm to silence it
4.Observe and follow all local and national electrical and building codes for installation.
5. This smoke alarm is designed to be used inside a single room only. In multi-room buildings, each
individual living unit should have its own smoke alarms. Do not install in non-residential buildings. And
this smoke alarm is not a substitute for a complete alarm system.
6. Smoke may not reach the smoke alarm for many reasons. For example, if a fire starts in a remote part of
the home, on another level, in a chimney, wall, roof, or on the other side of a closed door, smoke may not
reach the smoke alarm in time to alert household members. A smoke alarm will not promptly detect a fire
except in the area or room in which it is installed.
7. Smoke alarms may not alert every household member every time. The alarm sound is loud in order to
alert individuals to a potential danger. However, there may be limiting circumstances where a household
member may not hear the alarm (i.e. outdoor or indoor noise, sound sleepers, drug or alcohol usage, the
hard of hearing, etc.). If you suspect that this smoke alarm may not alert a household member, install and
maintain specialty smoke alarms. Household member must hear the alarm’s warning sound and quickly
respond to it to reduce the risk of damage, injury, or death that may result from fire. If a household
member is hard of hearing, install special smoke alarms with lights or vibrating devices to alert
occupants.
8. Smoke alarms can only sound their alarms when they detect smoke. Smoke alarms detect combustion
particles in the air. They do not sense heat, flame, or gas. This smoke alarm is designed to give audible
warning of a developing fire. However, many fires are fast-burning, explosive, or intentional. Others are
caused by carelessness or safety hazards. Smoke may not reach the smoke alarm QUICKLY ENOUGH to
ensure safe escape.
9. Smoke alarms have limitations. This smoke alarm is not foolproof and is not warranted to protect lives
or property from fire. Smoke alarms are not a substitute for insurance. Homeowners and renters are
responsible for insuring their lives and property. In addition, it is possible for the smoke alarm to fail at
any time. For this reason, you must test the smoke alarm weekly and replace every 10 years.
Note: For best protection, we recommend that you install a smoke alarm in every room.
