alarm device weekly to ensure proper operation.

2: If you're sure it isn't a really alarm, open windows or fan

the air around smoke alarm device for silence it

3: This smoke alarm device should be installed only by a

licensed, qualified electrician. Observe and follow all
local and national electrical and building codes for
installation.

4: This smoke alarm device is designed to be used inside a

single family only. In multifamily buildings, each
individual living unit should have its own smoke alarm
devices. Do not install in non-residential buildings. And
this smoke alarm device is not a substitute for a complete
alarm system.

5: Install a smoke alarm device in every room and on every

level of the home. Smoke may not reach the smoke alarm
device 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 device in time to alert
household members. A smoke alarm device will not
promptly detect a fire except in the area or room in which
it is installed.

6: Smoke alarm device may not alert every household

member every time. The alarm horn is loud in order to
alert individuals to a potential danger. However, there
may be some 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 device may not
alert a household member, install and maintain specialty
smoke alarm devices. 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 alarm devices with lights or
vibrating devices to alert occupants.

7: Smoke alarm devices can only sound their alarms when

they detect smoke or detect combustion particles in the air.
They do not sense heat, flame, or gas. This smoke alarm
device is designed to give audible warning of a developing
fire. However, many fires are fast - burning, explosive, or
intentional, and others are caused by carelessness or safety
hazards. In this circs, Smoke may not remake the unit

blow smoke away from the detector, interrupting its
alarm.

4: In rooms where temperatures may fall below 0℃ or rise

above 40℃, or in humidity higher than 93%. These
conditions will reduce battery life or cause a fault alarm.
