IMPORTANT !
THIS IS NOT A SMOKE ALARM! This CO alarm is designed to detect car-
bon monoxide from ANY source of combustion. It is NOT designed to detect
smoke, re, or any other gas.
WARNING ! This product is intended for use in ordinary indoor locations of
family living units. Do not expose to rain or moisture. The detector will not
protect against risk of carbon monoxide poisoning when the battery is at.
Do cover the alarm when decorating. REMEMBER to uncover the unit when
decoration is nished (excessive fumes from paints, solvents, cleaning agents,
etc. may damage or deteriorate sensor). The CO alarm shall not be seen as a
substitute for proper servicing of fuel-burning appliances, or the sweeping of
chimneys.

NEVER IGNORE THE CO ALARM
CO is called the “silent killer” because it is an invisible, odorless, tasteless gas
produced when fossil fuels do not burn completely, or are exposed to heat (usu-
ally re). These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane. Electrical appliances typically do not produce CO.
Many cases of reported CO poisoning indicate that while victims are aware
they are not well, they become so disoriented, that they are unable to save
themselves by either exiting the building or calling for assistance.
Be aware that CO poisoning may be the cause of u-like symptoms such as
headaches, tightness of chest, dizziness, fatigue, confusion and breathing dif-
culties. Because CO poisoning often causes a victim’s blood pressure to rise,
the victim’s skin may take on a pink or red cast. Extreme exposure to CO can
cause brain damage, death.
WARNING: EXPOSURE TO HIGH LEVELS OF CARBON MONOXIDE
CAN BE FATAL OR CAUSE PERMANENT DAMAGE AND DISABILI-
TIES.
COMMON RISKS FOR CO POISONING
Technical problems with equipment, depending on faults, lack of service •
or maintenance.
Faulty chimney or ventilation pipe which can have fallen or clogged(e.g. •
bird nest, snow, etc.)
Faulty ventilation direction of air, so called back draught.•
Faulty installation of burner.•
In equipment which is used regularly; for shorter periods of time, or by •
different people.
Chimneys of the wrong size etc.•
Garden grills which are used indoors.•

INSTALLATION:
CAUTION: DO NOT INSTALL THE ALARM IN NEW OR RENOVATED
BUILDINGS UNTIL ALL WORK IS COMPLETED, INCLUDING PAINT-
ING AND FINAL CLEANING (EXCESSIVE FUMES FROM PAINTS; SOL-
VENTS, MAY CAUSE DAMAGE AND DIRT OR DEBRIS MAY BLOCK
THE GAS ENTRY).

OPERATING AND TESTING CO ALARM
When the battery is installed, Green LED will ash once indicating the alarm
is powered and wait for about 1 minute to stabilize the sensor before testing the
unit. To test the unit, press and hold the button until the repeating series of 4
beeps sound with Red LED ashes. When the button is released, the siren will
stop.
Check and test the CO alarm after installation. Ensure that you can clearly hear
the CO alarm in sleeping area. It should be tested weekly and check after re-
occupation following a holiday.
Check that Green LED ashes about every minute to ensure the unit is in
operating mode.
If the Green LED is not ashing once per minute, or the unit does not respond
to the test button:
Make sure the unit contains the recommended type of battery 1.
Ensure the battery is installed correctly.2.
Make sure the unit has been cleaned adequately.3.
Check for obvious damage.4.
If the alarm still fails to work, it must be replaced immediately. Do not attempt
to repair it yourself, warranty will be void.
Note: The test push button is independent function with hush button. During
the normal testing mode, the silence feature will not active.
ADDITIONAL FEATURES
The CO alarm comes with the following friendly additional features for use.
Silence feature - This feature can be used to silence nuisance alarms. Press
test/silence button during alarm condition will silence the alarm signal for 4
minutes. If the CO surrounding level reaches 200 ppm, the alarm will reacti-
vate. Observe that the Red LED repeatedly series 4 ashes during hush model
last for 4 minutes. The unit will automatically return to normal mode after 4
minutes. If the concentration is increased, the silencer (hush) feature is by pass
and the unit will alarm.
CAUTION : If the CO concentration at 200 ppm the silence feature does not
activate. The user must be aware that if the alarms continually after push the
silence button, the CO concentration surrounding the alarm could be 200 ppm
or greater. Always determine why the alarm has been trigged before using the
silence feature. If the case of alarm is not clear, assure that there is an actual
CO leakage and evacuate the area.

Pre-alarm warning – when the unit detects CO level 40 ppm or greater, the
Red LED will ash every 8 seconds until alarm.
Memory function - When a unit alarms due to CO or other reasons (not from
test button), the memory function will be activated in the unit that has detected
the CO and will be held for 12 hours. The indication of an alarm incidence
being stored in the memory function consists of a short beep every 8 seconds.
During this memory indication period, the normal operating and function of the
unit is not affected and the user can reset/deactivate the memory function by
pressing the test push button until an alarm sounds.
Self diagnostics – Automatically check the sensor every 8s to ensure of correct
operating of alarm.
Low battery warning – When the battery power deteriorated, the unit will
emit one beep with Yellow LED ash every minute to remind user to replace
battery.
Fault warning – If a fault is detected, the unit will emit 2 beeps with Yellow
LED ash every 8 seconds to indicate the sensor is fault or not working prop-
erly so CO alarm must be replaced.
End of alarm life warning – When the CO alarm comes to end of life, the unit
will emit 3 beeps with Yellow LED ash every minute. When this happen, the
CO alarm must be replaced.
Temporary delay warning signal – When the time to replace battery or end
of life CO alarm warning occurs, the user can push the testbutton to temporar-
ily disable low battery- or end of life- warnings for 12 hours to avoid beeing
unnecessarily bothered by the signal especially in the middle of night. This is
indicated by 3 ashes with Red LED. User may press test button to alarm again
to deactivate function and return to warning mode at any time.
