1. General Information
This is a heat alarm device that is activated when it
reaches a preset minimum heat warning level
(around 59°C). It is not a smoke detector. If the heat
alarm is properly located and maintained, it will
detect dangerous heat levels caused by the
emergence of a fast flaming fire. Please note –
although this heat alarm is designed to detect
dangerous heat levels, it cannot prevent a fire.
Please read the User Manual carefully before you
install this heat alarm.

9. Precautions for use
• Test weekly.
• Do not paint the heat alarm.
• Both the heat alarm designed lifetime and battery
standby time (including weekly test) is 10 years.
The battery service time decreases if the alarm is
frequently activated for longer periods. Please
note - the battery is not replaceable.
• Heat alarms have limitations. This heat alarm is
not foolproof and is not warranted to protect lives
or property from fire. Heat alarms are not a
substitute for insurance. Homeowners and renters
should insure their lives and property. In addition,
it is possible for the heat alarm to fail at any time.
For this reason, you must test the heat alarm
weekly and replace it every 10 years.
• Heat alarms may not alert every household
member every time. The alarm siren 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 heat alarm
may not alert a household member, install and
maintain specialty alarms. Household members
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 heat and
smoke alarms with lights or vibrating devices to
alert occupants.
10. What to do in case of fire
1. Do not panic - stay calm!
2. Leave the building as quickly as possible. Touch
doors to feel if they are hot before opening them.
Use an alternate exit if necessary. Crawl along the
floor and do not stop to collect anything.
3. Meet at a pre-arranged meeting place outside the
building.
4. Call the fire department from outside the building.
5. Do not go back inside a burning building. Wait for
the fire department to arrive.
Note: These guidelines will assist you in the event of
a fire, however, to reduce the chance that fires will
start, practice fire safety rules and prevent
hazardous situations.
