Installation Instructions
Locations to install your CO alarm
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 alarm should be located outside primary sleeping areas
or on each level of your home. In the figure 1 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.

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 (hom e, offi ce, recrea tio nal vehic le or boat) even a
small accumulation of CO gas can be quite dangerous.
Although many products of combustion can cause discomfort and
adverse health eff ects, it is CO gas which pr esent s the grea test thr eat 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, yo ur na tural 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 (CO
not toxic. The products of combustion are exhausted from furnaces and
water heaters to the outside by means of a fuel duct or chimney.
), which is
2
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 v ents
(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 hea ter, gas ap plianc e, gas or ker osene heat er, gas or
oil furnace, and cigarette smoke.
More information about conditions which result in transient
CO situations
1.Excessive spillage or reverse venting of fuel burning appliances caused
by
(a.)Outdoor ambient conditions such as wind direction and or velocity
, including high gusts of wind; heavy air in the vent pipes (cold
humid air with extended periods between cycles)
(b.)Negative pressure .differential resulting from the use of exhaust
fans.
(c.)Simultaneous operation of several fuel burning appliances
competing for limited internal air.
(d.)Vent pipe connection vibrating loose from clothes dryers,
furnaces, or water heaters.
(e.)Obstructions in or unconventional vent pipe designs which amplify
the above situation.
2.Extended operation of unventilated fuel burning devices (range ,
oven,fireplace, etc)
3.Temperature inversions which can trap exhaust gases near the ground.
4. Car idling in an open or closed attached garage, or near a home
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 th e 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:
(a) Extreme exposure: unconsciousness, convulsions, cardio-
respiratory failure, death
(b) Medium exposure: severe throbbing headache, drowsiness,
confusion, vomiting, fast heart rate
(c) Mild exposure: slight headache, nausea, fatigue (similar to
"flu-like" symptoms)
Many victims of carbon monoxide poisoning indicate that while they were
aware that they were ill , they became so disoriented and confused that
they were unable to help themselves by either exiting the building or calling
for a assistance. Young children and household pets may be the first
affected. Exposure during sleep is particularly dangerous, because the
victim usually does not awaken.
Actions to take when CO alarm sounding
▲ WARNING!!
Actuation of your CO alarm indicates the
presence of carbon monoxide ( CO) which can kill you. If alarm
sounds :
1. Operate silence button
2. Call your emergency se rvices or fire department or 911
3. Immediately move to the fresh air –outdoor or by an open
door window.
In case of harmful level s of CO g as bein g dete ct ed, you r CO al arm M3 30
will go into a CO alarm mode as mentioned above. in “ CO Alarm Mode”
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 right away or 911. You should
evacuate all the people in the premises immediately. Do a head
count to check that everybody is accounted for.
(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 bu rning appliances and call a
qualified technician or your utility company to inspect an d repair
your problem before restarting appliances.
Normally an activation of the CO alarm indicates the prese nce of C O 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 CO alarm 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 CO alarm unit should be off. After waiting for
10 minutes, push the Test button to test the CO alarm unit so that you can
make sure that it is working properly again.
Test and silence your CO alarm
Follow the test proced ure describ ed here or cont act your CO a larm
unit dealer or installer for testing instructions . DSC recommended
that you test the entire alarm system at lea st one a week to v erify th e
operation of all functions.
The test/silence button is used to test if the CO alarm is working properly
and to mute the unit during alarm.
Test the unit
Press the test button and you should hear 4 short beeps with a
corresponding three LED flashes in 5 seconds , this cycle will repeat one
more time.
Familiarize yourself and your family members with this alarm pattern as
this testing simulates a actual CO alarm condition.
Silence the unit :
If the CO alarm is sounding, pressing the test/silence button will have the
alarm muted while at the same time red LED keeps flashing. After 4
minutes, if the CO concentration caused the alarm still remains at alerting
condition, the CO alarm will reactivate.
