Information about carbon monoxide:
CO - Carbon monoxide - is known as the “silent
killer” because it is odourless, tasteless and co-
lourless. It can kill in few minutes. This apparatus
may not prevent the chronic effects of Carbon
Monoxide exposure.
All people are at risk for CO poisoning. Unborn ba-
bies, infants, the elderly, and people with chron-
ic heart disease, anemia, or respiratory problems
are generally more at risk than others.
The apparatus will not fully safeguard individuals
at special risks
Breathing CO can cause headache, dizziness,
vomiting, and nausea. If CO levels are high
enough, you may become unconscious or die.

6. TEST FUNCTION:
After installation and at least once per quarter, test
your alarm to make sure it is operating correctly.
It is recommended to check visually every week
if the green LED ashes correctly (every minute)
When the top button is pressed the alarm sound-
er will sound, and when the button is released,
the alarm will make a self-test of the sensor and
battery for approximately 9 seconds. During this
delay the three LEDs will be ashed in sequence.
The result of the test will be indicated after the test
has been completed.
If the test passes, the green LED will emit for 3
sec. If the test fails, a fault indication will be given
(See section 11).
After the test function is performed, the alarm will
need to recover for one minute before the next
test can be done (to allow the sensor chamber to
re-settle after the test current is applied).
The alarm will also do a self-test every 24 hour
and test the sensor for faulty sensor, drift or short
circuit.
TIP: It is safe to cover the sound output hole with
your nger during the testing to minimize the
sound level emitted.
7. NORMAL MODE:
In normal mode, POWER indicator (Green LED)
will ash every 60 seconds
8. ALARM MODE:
When a dangerous concentration of CO is detect-
ed, the CO alarm will go into ‘Alarm Mode’. It will
be indicated by a series of repeated tones and the
red LED will ash every 0.5 second.
9. WHAT TO DO IF THE ALARM SOUNDS:
• Keep calm and open all doors and windows.
• If the alarm continues to be activated, then evac-
uate the premises.
• Get medical help for anyone suffering the effects
of carbon monoxide poisoning.
• Call the appropriate emergency central
10. HUSH FUNCTION:
Hush of the alarm is only possible under a level
of 200ppm. If you cannot hush the alarm, please
refer to section 9.
When the alarm is under CO alarm warning, it can
be silenced for about 10 minutes by pressing the
TEST/HUSH button.
When battery fault the indication can also be si-
lenced for up to 8 hours by a short press on the
TEST/HUSH button. This function can only be
carried out once during a fault.
11. FAULT WARNINGS:
Battery fault: Battery low condition is indicated
by a very short tone burst “beep” every 60 sec-
onds with yellow LED flashing. Your CO alarm
battery is low voltage.
Sensor fault: Sensor fault is indicated by two
very short tone burst “beeps” every 60 seconds
with yellow LED ashing. Your CO alarm will not
respond to CO.
End of life: End of sensor life is indicated by three
very short tone burst “beeps” every 60 seconds
with yellow LED ashing. Your CO alarm needs
to be replaced.
12. MAINTENANCE:
• Check if the alarm sounds and indicators
flash properly by pressing TEST/HUSH button
at least once per quarter.
• Your alarm should be vacuum cleaned once per
• quarter to remove dust and dirt. It can be wiped
with a damped cloth. Never use detergents or oth-
er solvents to clean the unit.
• Never attempt to disassemble the unit or clean
inside.
• Commonly occurring materials, vapours or
gases, e.g. in cleaning uids, polishes, paints,
cooking operations, etc., may affect the reliabili-
ty of the alarm in the short or long term.
• When household cleaning supplies or similar con-
taminants are used, the area should be venti-
lated.
• Please do not expose to rain or moisture and do
not knock or drop the detector. Open or tamper
with the alarm could cause malfunction.
