LOCATIONS TO INSTALL YOUR DETECTOR
Since CO gas moves freely in the air, the suggested location is in or as near as possible to
sleeping areas of the home. The human body is most vulnerable to the effects of CO gas
during sleeping hours. For maximum protection, a CO detector should be located outside
primary sleeping areas or on each level of your home. In the figure below, are suggested
locations in the home. The electronic sensor detects carbon monoxide, measures the
concentration and sounds a loud alarm before a potentially harmful level is reached.

In addition, The i4H-CO-M330 detector is designed to do a continuous self diagnostic
check of its microprocessor circuitry when in use.
TAKING CARE OF YOUR DETECTOR
You have to maintain the i4H-CO-M330 detector frequently to ensure it working properly.
Few tips are provided for you to take care of your detector:
1 Use a vacuum cleaner to clean the air vents regularly to keep them free of dust.
2 Push the Test Button on your detector to test its operating function once every week.
You can set i4H-LS-20to “Test Mode” to avoid triggering siren and calling.
MEANINGS OF LED INDICATION & BUZZER
The red and green, yellow LED light and buzzer turn on and/or off to indicate various
situations. There are a few different LED light and buzzer operations:
Mounting Bracket
Tamper
Switch

When stand-by, the green LED flashes once in every 60 seconds.
When alarm, the red LED flashes and beep 4 times in every 5 seconds.
Low battery warning, the yellow LED flashes and beep once in every 60 seconds.
If malfunction, the yellow LED flashes 3 times and beep once in every 60 seconds.
In alarm, low battery or malfunction conditions a corresponding RF signal will be sent
out and the i4H-LS-20base unit will record the status and react properly.
ACTIONS TO TAKE WHEN ALARM SOUNDING
In case of harmful levels of CO gas being detected, The i4H-CO-M330 detector will go
into a continuous full alarm. Try to take the following necessary actions immediately:
1 If there is anyone experiencing the effects of carbon monoxide poisoning such as
headache, dizziness, nausea or other flu-like symptoms, call your fire department or
911 right away. You should evacuate all the people in the premises immediately. Do a
head count to check that everybody is accounted for.
2 Do not re-enter the premises until the problem has been corrected and the CO gas has
been dispersed out and a safe level is reached.
3 If no symptoms exist, Immediately ventilate the home by opening windows and doors.
Turn off fuel burning appliances and call a qualified technician or your utility
company to inspect and repair your problem before restarting appliances.
WARNING:Normally an activation of the detector indicates the presence of CO gas.
However, the CO gas can be extremely fatal, if it is not detected. The source of the CO gas
may come from several possible situations, please refer to the list of sources of carbon
monoxide on page 3.
CAUTION: This detector will only indicate the presence of CO gas at the sensor. However,
you have to be aware that the CO gas may be present in other areas in the premises.
ACTIONS TO TAKE AFTER THE PROBLEM BEING CORRECTED
Once the problem about the CO gas presence in the premises has been corrected, the alarm
of the detector should be off. After waiting for 10 minutes, push the Test button to test the
CO-M330 detector so that you can make sure that the detector is working properly again.
TECHNICAL INFORMATION
The CO-M330 Detector is engineered to be able to provide alarm sounds based on the BS
standards due to various exposure time at different level of carbon monoxide concentrations.
UL2034 and EN50291 have already established the carbon monoxide concentrations and
exposure time standards for the alarms, which is specified below:
A full alarm is activated under the following conditions:
- In less then 30 minutes at exposures of 150 ppm
- In less than 6 minutes at exposures of 350 ppm
YOU SHOULD KNOW ABOUT CARBON MONOXIDE
Carbon monoxide, also known as "CO" by the chemical form, is considered to be a highly
dangerous poisonous gas, because it is colorless, odorless or tasteless and very toxic. In
general, biochemistry phenomena have shown that the presence of CO gas inhibits the
blood's capacity to transport oxygen throughout the body, which can eventually lead to brain
damage.
In any enclosed space (home, office, recreational vehicle or boat) even a small accumulation
of CO gas can be quite dangerous.

Although many products of combustion can cause discomfort and adverse health effects, it
is CO gas which presents the greatest threat to life.
Carbon monoxide is produced by the incomplete combustion of fuels such as natural gas,
propane, heating oil, kerosene, coal, charcoal, gasoline, or wood. The incomplete
combustion of fuel can occur in any device which depends on burning for energy or heat
such as furnaces, boilers, room heaters, hot water heaters, stoves, grills, and in any
gasoline powered vehicle or engine (e.g. generator set, lawnmower). Tobacco smoke also
adds CO to the air you breathe.
When properly installed and maintained, your natural gas furnace and hot water heater do
not pollute your air space with CO. Natural gas is known as a "clean burning" fuel because
under correct operating conditions, the combustion products are water vapor and carbon
dioxide (CO2), which is not toxic. The products of combustion are exhausted from
furnaces and water heaters to the outside by means of a fuel duct or chimney.
Correct operation of any burning equipment requires two key conditions:
1 An adequate supply of air for complete combustion.
2 Proper venting of the products of combustion from the furnace through the chimney,
vent or duct to the outside.
Typical carbon monoxide gas problems are summarized here:
1 Equipment problems, due to defects, poor maintenance, damaged and cracked heat
exchangers
2 Collapsed or blocked chimneys or flues, dislodged, disconnected or damaged vents
3 Downdraft in chimneys or flues. This can be caused by very long or circuitous flue
runs, improper location of flue exhaust or wind conditions
4 Improper installation or operation of equipment, chimney or vents
5 Air tightness of house envelop/inadequate combustion of air
6 Inadequate exhaust of space heaters or appliances
7 Exhaust ventilation/fireplace competing for air supply
Potential sources of carbon monoxide in your home or office include clogged chimney,
wood stove, wood or gas fireplace, automobile and garage, gas water heater, gas appliance,
gas or kerosene heater, gas or oil furnace, and cigarette smoke.
POSSIBLE SYMPTOMS OF CARBON MONOXIDE POISONING
Carbon monoxide is colorless, odorless, tasteless, and very toxic. When inhaled, it produces
an effect known as chemical asphyxiation. Injury is due to the combining of CO with the
available hemoglobin in the blood, lowering the oxygen-carrying capacity of the blood. In
the presence of CO gas, the body is quickly affected by oxygen starvation.
The following symptoms are related to CO poisoning and should be discussed with all
members of the household so that you know what to look for:
1 Extreme exposure: unconsciousness, convulsions, cardio respiratory failure, death.
2 Medium exposure: severe throbbing headache, drowsiness, confusion, vomiting, fast
heart rate.
3Mild exposure: slight headache, nausea, fatigue (similar to "flu-like" symptoms).
Young children and household pets may be the first affected. Exposure during sleep is
particularly dangerous, because the victim usually does not awaken.

WARNING AND LIMITATION
This detector may not alarm at low carbon monoxide levels. The Occupational Safety and
Health Association (OSHA) has established that continuous exposure levels of 50 ppm
should not be exceeded in an 8 hours period. Individuals with a medical problem may
consider more sensitive detection devices.
The CO gas detector is not suitable as a smoke or fire detector. This detector is not suitable
to install in a hazardous location, as defined in the National Electrical Code.
This detector will not work without power. The i4H-CO-M330 detector will not work if
the battery is disconnected or bad for any reason. Additionally, carbon monoxide must
reach the detector for the proper performance of CO gas detection.
Carbon monoxide detectors may wear out because they contain electronic parts that fail at
any time. Test your detector at least every week (see the section "TESTING YOUR
DETECTOR").
Important notice: The i4H-CO-M330 uses an electrochemical sensor whose life is
about 5 years, the user should replace a new i4H-CO-M330 before its life time expires.
