PRESS TEST BUTTON:
(1)Press the test/reset button, the blue back light will be lighted. And the unit
beeps four times with red led flashes four times. Then it will display the highest
CO concentration which have been detected by the detector since it was tested
from the last time to press TEST button.
(2) Then the unit will beep one time with red LED flashes one time. The the LCD
will display “t t t”with the three LEDs flash one by one. This means that the units is
on self-testing.
(3)When the self-test is completed, the LCD will display “PAS”with three beeps
and three LEDs flash three times in the same time if the unit is working well. Then
the LCD will display “CO”with no backlight and then display “0ppm”.
If the unit was tested with fault working status, the LCD will display “Err”with
yellow LED flash two times and the buzzer will beep two times in the same time.
And this will circulate every 60 seconds.
HUSH:
When the CO detector is alarming for the danger concentration of CO, you can
press the test button and the detector will be hushed for 5 minutes. The alarm
sound will be pulsed with blue back light turned off. And the green LED is lighted.
The detector will resume to normal monitor status after 5 minutes. If the CO is still
in dangerous level, the detector will continue to alarm.
Installation Location:
Where To Install Your CO Detector
If you have only one detector,
place it near sleeping areas, not
near fuel burning appliances,
such as fireplaces, furnaces or
hot water heaters.

The following suggestions are intended to help you with the placement and
installation of your CO detector.
• Place out of the reach of children. Under no circumstance should children be
allowed to handle the CO detector.
• Install in a bedroom or hallway located close to the sleeping area. Take special
care to verify the alarm can be heard in sleeping areas.
• It is recommended that a CO detector be installed on each level of a multilevel
home.
• Locate at least 5 feet away from all fuel burning appliances.
• Placing at eye level (around 150cm -300cm from the floor) allows for optimum
monitoring of the red and green indicator lights.
• It is permissible to mount the detector on the height of bed in the bedroom or lay
it on the bedside night table (CAUTION ! - please take into account the very loud
alarm!)
• In exceptional circumstances, the detector can be used as a portable device and
take it where you want to detect a threat. The detector should move with caution.
Moving the sensor can cause damage and void the warranty.
Where Not To Install Your CO Detector !
Do not install in kitchens, garages or furnace rooms that may expose the sensor to
substances that could damage or contaminate it.
Do not install within 60cm of heating or cooking appliances.
Do not install near vents, flues, chimneys or any forced/unforced air ventilation openings.
Do not install near ceiling fans, doors, windows or areas directly exposed to the weather.
Do not install in dead air spaces, such as peaks of vaulted ceilings or gabled roofs, where
CO may not reach the sensor in time to provide early warning.
Do not install this unit near deep-cell large batteries. Large batteries have emissions that
can cause the alarm to perform at less than optimum performance.
Do not obstruct the vents located on the alarm. Do not place the alarm where drapes,
furniture or other objects block the flow of air to the vents.
Installation Instructions
Mounting
1. Using the template provided. Mark the position of the two mounting holes by using the
template.
2. Drill two holes using a 6mm drill for the plastic plugs supplied, (ensure you don’t drill into
the house wiring).
3. Screw the unit to the wall.

Your detector detects a threat only where it is installed. Carbon
monoxide must reach detector in described level and time to start
alarming.
Caring for your Carbon Monoxide Detector
To keep your CO detector in good working order, you must follow these simple
steps:
•Test the detector once a month by pressing the Test/Reset button
•Vacuum the detector cover once a month to remove accumulated dust. Use the
soft brush attachment of your vacuum cleaner, and unplug the detector from the
electrical outlet before vacuuming.
•Instruct children never to touch, unplug or otherwise interfere with the unit. Warn
children of the dangers of CO poisoning.
•Never use detergents or solvents to clean the detector. Chemicals can
permanently damage or temporarily contaminate the sensor.
•Avoid spraying air fresheners, hair spray, paint or other aerosols near the CO
detector.
This CO alarm meets these alarm response times (As required in EN50291)
At 50 PPM, the unit must alarm within 60-90 minutes
At 100 PPM, the unit must alarm within 10-40 minutes
At 300 PPM, the unit must alarm within 3 minutes

•Do not paint the CO detector. Paint will seal the vents and interfere with proper
sensor operation.
•Do not mount the CO detector directly above or near a diaper pail, as high
amounts of methane gas can cause temporary readings on the digital display.
What to do When the Alarm Sounds
(1) Operate the Test/Reset button;
(2) Call your emergency services;
(3) Immediately move to fresh air - outdoors or by an open door/window. Do a head count to
check that all persons are accounted for. Do not reenter the premises nor move away from
the open door/window until the emergency services responders have arrived, the premises
have been aired out, and your alarm remains in its normal condition.
(4) After following steps 1-3, if the alarm reactivates within a 24 hour period, repeat steps 1-3
and call a qualified appliance technician to investigate sources of CO from fuel burning
equipment and appliances, and to inspect for proper operation of equipment.
If problems are identified during this inspection, have the equipment serviced immediately.
Note any combustion equipment not inspected by the technician and consult the
manufacturer’s instructions, or contact the manufacturer’s directly for more information about
CO safety and the equipment. Make sure that motor vehicles are not, or have not been,
operating in a garage attached or adjacent to the residence.
If the alarm is sounding, pressing the test/reset button will terminate the alarm. If the CO
condition that caused the alert in the first place continues, the alarm will reactivate. If the unit
alarms again within five minutes, it is sensing high levels of CO which can quickly become a
dangerous situation.
