This unit is a photoelectric smoke alarm. The photoelectric
technology, it is more sensitive in detecting slow smoldering
fires which generate light smoke, little heat and may smolder
for hours before bursting into flames. This smoke alarm does
not contain any radioactive material. Smoke alarms should be
installed in every room (except the bathroom and kitchen),
finished attics and basements, making sure the people in the
home will be able to hear and respond to the alarm sound.
For minimum protection, you should install an alarm on
every level of the home particularly outside sleeping rooms.

minimum of one smoke alarm on each occupiable level of the
home. Install a smoke alarm on the ceiling or wall inside

Important Safety Information:
1. The test button accurately tests smoke alarm functions. Do
not use any other test method. Test smoke alarm 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 to test and silence it.
3. THIS EQUIPMENT SHOULD BE INSTALLED IN
ACCORDANCE WITH
PROTECTION ASSOCIATION'S
(National Fire Protection Association, Batterymarch
Park,Quincy, MA 02269).
4. This smoke alarm is designed to be used inside a single
family home only. In multifamily buildings, each
individual living unit should have its own smoke alarms.
Do not install in non-residential buildings as this smoke
alarm is not a substitute for a complete alarm system.
5. Install a smoke alarm in every room and on every level of
the home. 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.
6. Smoke alarm 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 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 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
