sounder may sound for 1 s. This is normal and indicates that the battery is
positioned properly.
2.
Close the smoke & heat alarm and mounting base.

Tests
1.
Press and hold the Test button for 3 s to check the smoke & heat alarm
audible warning operates and the red LED flashes rapidly.
WARNING
: The smoke & heat alarm has a loud alarm signal. Use
hearing protection when testing smoke & heat alarms.
1.
For interconnected smoke & heat alarms, press and hold the Test button
for 3 s on each smoke & heat alarm, and check the smoke & heat alarm
sounder operates on all interconnected smoke & heat alarms.
2.
Check that the red LED in the Test button operates only on the smoke &
heat alarm being tested.
NOTE: Smoke & heat alarms should be interconnected within only one family
residence. Otherwise, you might encounter nuisance alarms when a smoke &
heat alarm is operated or tested in another residence.
Normal Operation
Once installed and tested, your smoke & heat alarm will immediately start
monitoring for smoke/heat. If the sounder in the smoke & heat alarm operates,
check for a fire and execute your safety plan.
If the alarm was caused by a nuisance situation, open a window or fan the air
to remove the smoke or dust from within the smoke & heat alarm. The alarm
will turn off as soon as the air is completely clear. Do not disconnect the mains
power and battery to silence the smoke & heat alarm.
Hush
WARNING
: Before using the Hush feature, identify the source of
smoke/heat and be certain that safe conditions exist.
If investigation of the alarm signal is likely caused by a known nuisance source
(such as cooking fumes/steam), the Hush button can be pressed to silence the
smoke & heat alarm for 10 min. Press the Hush button again will return the unit
to normal operation.
The red LED on smoke & heat alarm will flash once every 6 s while in the Hush
condition.
After the Hush time has expired, the smoke & heat alarm will return to normal
sensitivity. If smoke is still present, the alarm will re-activate. The Hush feature
can be used repeatedly.
Care and Maintenance
Weekly Tests
1.
Press and hold the Test button for 3 s on each smoke & heat alarm.
2.
Check the smoke & heat alarm sounder operates with a loud pulsating
sound, and the red LED in the Test button flashes rapidly.
WARNING
: The smoke & heat alarm has a loud alarm signal. Use
hearing protection when testing smoke & heat alarms.
3.
For interconnected smoke & heat alarms, check the smoke & heat alarm
sounder operates with a loud pulsating sound on all interconnected
smoke & heat alarms and the red LED in the Test button operates only
on the smoke & heat alarm being tested. Repeat the test on all
interconnected smoke & heat alarms.
The alarm shall also be tested when back from a long away/vacation from
the house.
WARNING
: Never use a naked flame of any kind to test your smoke &
heat alarm. You may set fire to and damage the smoke & heat alarm,
as well as your home. The built-in Test button accurately tests all
alarm functions.
Annual Maintenance
1.
Vacuum or carefully wipe the cover of the smoke & heat alarm to remove
any dust, lint or dirt around the openings of the smoke & heat alarm. Do
not spray aerosols into the smoke & heat alarm.
2.
After annual maintenance, test all smoke & heat alarms.
Low Battery Alert
When the battery becomes depleted, the smoke & heat alarm will signal a
short beep every 48 s. Immediately replace the battery with an approved
model (see the section User Replaceable Parts).
NOTE: Batteries supply a lower voltage in cold conditions, so the Low Battery
signal may start operating late at night. To avoid annoyance, keep a spare
battery on hand. The Low Battery signal will operate for at least 30 days.
Protection From Fire
Installing smoke & heat alarms is only one step in protecting your family from
fires. You should also reduce the chances that fires will start in your home and
you must increase your chances of escaping safely if one does start. The
following information will help you develop a fire safety program.
1.
Install smoke & heat alarms properly. Carefully follow all the instructions
in this manual. Keep your smoke & heat alarms clean, and test them
every week.
2.
Non-working smoke & heat alarms will not alert you. Replace your
smoke & heat alarms immediately if they are not working properly.
3.
Follow fire safety rules, and prevent hazardous situations:
•
Use smoking materials properly. Never smoke in bed.
•
Keep matches and cigarette lighters away from children.
•
Store flammable materials in proper containers. Never use them
near open flames or sparks.
•
Keep electrical appliances in good condition. Do not overload
electrical circuits.
•
Keep stoves, fireplaces, chimneys, and barbecue grills grease free.
Make sure they are properly installed and away from any
combustible materials.
•
Keep portable heaters and open flames such as candles away
from combustible materials.
•
Do not allow rubbish to accumulate.
•
Keep a supply of extra batteries on hand for your battery powered
smoke & heat alarms.
Prepare and practice a family escape plan. Review the following with your
children each time you have fire escape drills. This will help everyone
remember them in case of a real fire emergency.
1.
Don’t panic and stay calm. Your safe escape may depend on thinking
clearly and remembering what you have practiced.
2.
Get out of the house as quickly as possible. Follow a planned escape
route. Do not stop to collect anything or to get dressed.
3.
Feel the doors to see if they are hot. If they are not, open them carefully.
Do not open a door if it is hot. Use an alternate escape route.
4.
Stay close to the floor. Smoke and hot gases rise.
5.
Cover your nose and mouth with a wet or damp cloth. Take short,
shallow breaths.
6.
Keep doors and windows closed. Open them only if you have to in order
to escape.
7.
Meet at your planned meeting place after leaving the house.
8.
Call the Fire Service as soon as possible from outside your house. Give
the address and your name.
9.
Never go back inside a burning building.
10. Contact your local Fire Service. They will give you more ideas about how
to make your home safer from fires and how to plan your family’s
escape.
