SMOKE DETECTOR MODES
STANDBY MODE
Green LED flashing once every 48 seconds means the smoke detector is
in standby (operating) mode.
ALARM MODE
Red LED flashing 3 times and horn emit 3 tones every 4 seconds.
SILENCE FEATURE
The silence features can temporarily mute an alarm for up to 8 minutes.
To use this feature, press test/silence button on the smoke detector when
it alarms. If the smoke concentration around the smoke detector is still at
an alarming level after 8 minutes of silence, then the smoke detector will
re-alarm immediately.
MALFUNCTION (ERROR) SIGNAL
Please remove and replace the smoke detector if:
Horn emits sound 1 time and yellow LED flashing once 48 seconds:
Detector does not work properly.
Horn emits sound 3 times and yellow LED flashing 1 time:
Smoke trouble.
Horn emits sound 2 times and yellow LED flashing 1 time:
“Low sensitivity”.
.
Horn emits sound 2 times and yellow LED flashing 2 times:
“High sensitivity”.
Horn emits sound 1 time and yellow LED flashing 1 time:
The detector has low battery voltage.
HUSH FEATURE
The hush feature can temporarily mute warning of malfunctions for up to
one hour. To use this feature, press the test/silence button when the
smoke detector is in warning (malfunction) mode. To return the smoke
detector to audible warning mode, press the test/silence button again.
LOW BATTERY WARNING SIGNAL
If the smoke detector horn begins to beep once every 48 seconds with
yellow LED flashing, then the battery of the smoke detector is weak. This
low battery warning signal should last for up to 7 days. The SMK2 battery
for smoke detection is not replaceable so the detector must be replaced
with a new unit.
END OF LIFE SIGNAL
After 10 years of operation, an audible indication will be given that the
smoke detector should be replaced. This indication is distinguished by
horn emit sound 1 time and yellow LED flashing 4 times every 48
seconds.
MANUAL TEST OF THE SMOKE DETECTOR
Test the smoke detector both at installation and then regularly (at least
monthly) by pressing firmly on the test button with your finger for around 1
second until the horn sounds and then release your finger. The alarm horn
will emit sound at least 3 times with the red LED flashing. If the smoke
detector emits sound with yellow LED flashing every 48 seconds after the
test is done, then the smoke detector is not working properly. See section
“
MALFUNCTION (ERROR) SIGNAL
”.
This type of test is the
only way to make sure that the smoke
detector unit is working properly. If the unit fails this test, then it
must be replaced immediately
.
If you have been away from home more than 1 week, always test the
detector manually when you return to home.
NOTE:
If no manual test has been performed for 28 days, the device will
do an automatic self-test to determine if everything is okay. The alarm horn
will emit sound during this test.
WARNING:
Never use an open flame of any kind to test your smoke
detector since you may cause fire damage to the smoke detector or your
home. The built-in test button accurately tests all functions and is the only
correct way to test the unit.
WARNING
:
When you are not testing the unit, but the alarm horn sounds,
then the smoke detector has sensed smoke or combustion particles in the
air. Investigate the cause of the alarm and take proper actions if the alarm
is correct. The alarm could be caused by a nuisance situation, such as
cooking smoke or a dusty furnace. If this happens, open a window, or fan
the air to remove the smoke or dust. The alarm will turn off as soon as the
air is completely clear.
WARNING:
Do not dismantle, disconnect the power, or remove the
battery from the smoke detector. This will remove your protection from
fires
.
NOTE:
If the smoke detector horn begins to emit sound once in 48
seconds with yellow LED flashing, then the smoke detector
’s battery is
weak.
NOTE:
Only use the replacement lithium batteries listed below:
1. (Duracell) DL123A
2. (Panasonic) CR123A
.
WARNING:
Do not use any other type of battery. The RF module of this
smoke detector may not operate properly with another type of battery.
BATTERY INSTALLATION
1. Open battery compartment (see figure below).
2. Install 3V batte
ry into compartment and make sure the “+” and “-“ ends
of the battery are aligned properly and close the hatch.
3. After the battery is installed, mount it on the bracket and press the test
button immediately to check if it alarms properly.
CAUTION:
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type.
CAUTION:
This smoke detector comes with a cover latch that will
prevent the smoke detector cover from closing if the battery is not installed.
This tells you that the smoke detector will not work until a battery is
properly installed.
TAKING CARE OF YOUR SMOKE DETECTOR
Your SMK2 smoke detector is designed to be as maintenance-free as
possible. To keep your smoke detector in good working condition, you
must test the unit according to
section “
MANUAL TEST OF THE SMOKE
DETECTOR
”.
Regular Maintenance:
Open the cover and vacuum the dust off the smoke detector
’s sensing
chamber at least once a month.
To clean the smoke detector, use soft brush attachment on your vacuum.
Carefully remove any dust on smoke detector components, especially on
the openings of the sensing chamber. Test the smoke detector to make
sure battery is working correctly. Never use water cleaners as they may
damage the unit.
NOTE:
If nuisance alarms keep coming from the unit, you should check
if the smoke detector
’s location is adequate. Refer to section “
WHERE
TO INSTALL SMOKE DETECTOR
” and move your smoke detector if it
is not located properly. Clean the unit as described above.
