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.
Figure 3
below indicates the 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.
ʳ
Do not place the CO alarm in the following areas:
(a) Where the temperature may drop below 4.4
͍˖
or exceed 37.8
͍˖ˁʳ
(b) Near paint thinner fumes
(c) Within 5 feet (1.5 meter) 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 close proximity to an automobile exhaust pipe; this
will damage the Alarm
(f) Keep the CO alarm away from excessively dirty, dusty or greasy
areas such as kitchens and garages. Ensure adequate ventilation
when using household cleaners and chemicals as these can affect
the sensor.
Installing the CO Alarm
The WS4913 CO alarm is easy to install to protect you and your family in
your home, cottage, cabin and/or office.
To install the CO alarm (See figure 4. as below):
1. For a wall mounted location, the detector should be at least six
inches(15cm) from the ceiling; for a ceiling mounted location, the
detector should be at least 12 inches (30.5cm) from any wall.
2. Prior to mounting the WS4913 in its final location be sure to perform the
wireless device placement test to ensure reliable communication with
the control panel. Refer to the
PC9155-433
Installation manual,
section 904
for details.
3.
At the place where you are going to install the alarm, draw a straight
line four (4) inches (10cm) long.
4. Remove the mounting bracket from your unit by rotating it
counterclockwise.
5. Place the bracket so that the two longest hole slots are aligned on the
line. In each of keyhole slots, draw a mark to locate a mounting plug
and screw.
6. Remove the bracket.
7.
Using a 3/16-inch (5mm) drill bit, drill two holes at the marks and insert
wall plugs.
8.
Using the two screws and wall plugs supplied, attach the bracket to
the wall.
9.
Carefully center the WS4913 on the mounting bracket and turn it
clockwise to fix it into place. Pull outward on the alarm to make sure it
is securely attached to the mounting bracket.

Device Enrollment
The 6 digit serial number located on the back of the CO alarm housing
must be used to enroll the CO alarm onto the alarm control panel using
Installers programming mode. To ensure there is no interference with
similar systems in the adjacent units of a multilevel multiunit dwelling such
as an apartment building, the PC9155-433 has been designed such that
each installation has a unique System Identification code which works in
conjunction with the device serial numbers. Please refer to your control
panel
installation manual
for details.

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) 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 (CO
2
), 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.
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 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:
(a) Mild exposure: slight headache, nausea, vomiting, fatigue (often
described as "Flu-like" symptoms).
(b) Medium exposure: severe throbbing headache, drowsiness,
confusion, fast heart rate
(c)
Extreme exposure: unconsciousness, convulsions, cardio-
respiratory failure, death.
(d) Many cases of reported CARBON MONOXIDE POISONING indicate
that while victims are aware they are not well, they become so
disoriented they are unable to save themselves by either exiting the
building or calling for assistance. Young children and household
pets are typically the first affected.
