What 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,
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 closed 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:

(a) An adequate supply of air for complete combustion.
(b) 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:
(a) Equipment problems, due to defects, poor maintenance, damaged and

cracked heat exchangers
(b) Collapsed or blocked chimneys or flues, dislodged, disconnected or

damaged vents
(c) Downdraft in chimneys or flues. This can be caused by very long or

circuitous flue runs, improper location of flue exhaust or wind

conditions
(d) Improper installation or operation of equipment, chimney or vents
(e) Air tightness of house envelop/inadequate combustion of air
(f) Inadequate exhaust of space heaters or appliances
(g) 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.

Installing the Detector

Selecting the installation location

Since CO gas moves freely in the air, the suggested location is in or as near
as possible to sleeping areas of the home, 30 cm (12 inch) below the ceiling .
For maximum protection, a CO detector should be located outside the
primary sleeping areas or on each level of your home (see Fig 1 for
suggested locations).

Fig. 1

IMPORTANT:

This device is not suitable for installation in a hazardous location, as
defined by the US National Electrical Code.

Do not place the detector in the following areas:
(a) Where the temperature may drop below 4°C (39°F) or exceed 38°C

(100°F).
(b) Near paint thinner fumes
(c) Within 1.5 meter (5 feet) of open flame appliances such as furnaces,

stoves and fireplaces
(d) In exhaust streams from gas engines, vents, flues or chimneys
(e) Do not place in proximity to an automobile exhaust pipe; this will

damage the detector

To install the detector:

1. Remove the mounting bracket from your unit according to Fig. 2.

the mounting bracket until a click is heard (see arrow direction, Fig 3).

8. Pull the detector outwards to make sure that it is securely attached to

the mounting bracket.

Transmitter/Receiver Communication Setup

1. Set the receiver to Learn mode.

2. A Write message is sent 10 seconds after the insertion of batteries

into compartment

- and in addition -

When the Tamper is pressed for 3 seconds (the button is pressed

when the detector is placed on the mounting bracket).

3. Verify that the detector has been identified by the receiver.

LED & BUZZER Indication

Testing And Resetting Your Detector

A green power light indicates that power is supplied. To test the detector, press
the Test button. The detector will beep intermittently and the three LEDs will flash.
Release the Test button. The beep and the three LEDs will stop and the green
LED remains on or flashes every 60 seconds.

Muting Your Detector

You can partially mute the detector in an event of alarm by pressing the Test
Button. The Red LED will continue to flash and a short beep will be heard every
16 seconds.

Detector Malfunctioning

A malfunctioning unit is indicated by beep-sounding on and off sequentially, i.e.,
beeping for 3 seconds with 3 seconds delay between two beeps. If this occurs,
remove the batteries from the unit for 10 seconds and then install them again.
Should the unit again beep intermittently, DO NOT use this detector. Send the
malfunctioning unit to the manufacturer for servicing.

Taking Care Of Your Detector

You have to maintain the detector to ensure proper operation:

1. Use a vacuum cleaner to clean the air vents occasionally to keep them free
of dust.

2. Press the Test button on your detector to test its operation once every week.

Actions to Take When Alarm Sounding

In case of harmful levels of CO gas being detected, your detector will go into a
continuous full alarm. Try to take the following necessary actions immediately:
(a) 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 emergency service department right away. You should
evacuate all the people in the premises immediately. Do a head count to
check that everybody is present.

(b) 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.

(c) 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 in page 1.
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 is Corrected

Once the problem of the CO gas presence in the premises has been corrected,
the detector alarm should be off. After waiting for 10 minutes, push the Test
button to test the detector, and by that, being confident that the detector is working
properly again.
