Supervised Indoor Wireless CO Gas Detector
Installation Instructions
1. INTRODUCTION
The carbon monoxide (CO) detector is designed to monitor the
CO gas level in residential dwellings and give early warning
before potentially dangerous levels exist. The CO alarm is
transmitted to the PowerMax+ (version F and up) or PowerMax
Pro and presented on its display.
The CO gas is considered to be a highly dangerous poisonous
gas because it is colorless, odorless, tasteless and very toxic.
Presence of CO gas inhibits the blood's capacity to transport
oxygen throughout the body, which can eventually lead to brain
damage. CO gas is produced by incomplete combustion of fuels
(such as natural gas, propane, heating oil, kerosene, coal,
charcoal, gasoline or wood) that can occur in any device that
depends on burning for energy and heat (such as furnaces,
boilers, room heaters, hot water heaters, stoves, grills and in any
gasoline powered vehicle or engine).
Before CO harmful level is reached, the detector's internal buzzer
beeps sound periodically and the detector's red LED flashes. In
this condition, the buzzer sound can be stopped for 6 minutes by
pressing the TEST/MUTE switch. It will not correct the CO gas
problem, but will temporarily silence the buzzer while you correct
the problem. After 6 minutes, the detector restarts alarm if the CO
level remains high.
The detector provides
low battery and detector
end-of-life indications.
Caution
: The
detector expiry date is
stamped on the
detector. After the
expiry date, the
detector should not
be used - do not wait
for end-of-life
indication!!

The detector is continuously self-tested and has a TEST button
that enables the user to test the detector anytime.
Note: The TEST/MUTE switch functions as TEST switch (in
normal operation) or as MUTE switch (in alarm condition).
The tamper switch actuator (fig. 3), is pressed against the bracket
when the unit is attached to the bracket. Removal of the unit from
the bracket causes the switch contacts to open, creating a tamper
event, which is reported by the transmitter to the alarm system
control panel.

APPENDICES
Appendix A - CO Detector Installation Overview
A-1. Selecting Installation Location
Selecting a suitable location is critical for the CO detector. The
Consumer Product Safety Commission (CPSC) recommends to
use at least one CO detector per household, located near as
possible to sleeping area of the home, because the human body
is most vulnerable to the CO gas effect during sleeping hours.
For added protection, install additional CO detector in every separate
bedroom and on every level of your home. If your bedroom hallway is
longer than 14 meters (40 feet), install a CO detector at BOTH ends
of the hallway. Install an additional detector 6 meters (20 feet) away
from the furnace or fuel burning heat source.
For maximum protection, the detector should be also located
outside primary sleeping areas or at each level of your home.
Mount the detector on a firm wall or ceiling.

A-2. Where Not to Install CO Detectors
1. In location where temperature may be below -10°C (14°F) or
above 40°C (104°F).
2. In locations where humidity is below 10% or above 93% RH.
3. Near paint thinner fumes.
4. Near air conditioners, furnaces, stoves, fireplaces and any
other ventilation source that may interfere with the CO gas
entering the detector.
5. In locations where furniture or draperies may obstruct the air flow.
6. In exhaust streams from gas engines, vents, flues or
chimneys.
7. Where dirt or dust could collect and block the sensor and stop
its working.
8. In locations that can be reached by children.
9. In turbulent air from ceiling fans.
10. In close proximity to an automobile exhaust pipe - this will
damage the detector.
Appendix B - CO Gas Health Effects
B-1. Toxic Effects
Carbon monoxide (CO) is a colorless, odorless non-irritating gas
which is classified as a chemical asphyxiate whose toxic action is a
direct result of the hypoxia produced by a given exposure.
CO is rapidly absorbed through the lungs, diffuses across the alveolar
capillary membrane and is reversible bound with hemoglobin as
carboxyheoglobin (COHb), however a minute amount is present in
the plasma. The affinity of hemoglobin for CO is over 200 times its
affinity for oxygen. This reduces the oxygen carrying of the blood and
also has an effect on dissociation of oxyhemoglobin which farther
reduces the oxygen supply to the tissues. CO is chemically
unchanged in the body and is eliminated in the expired air. The
elimination is determined by the same factors that applied during
absorption.
If the Co level in the inhaled air is constant, the level of COHb in the
blood will approach an equilibrium state after several hours. However,
the rate at which the equilibrium is reached depends on many factors,
e.g. lung ventilation rate (physical activity) and alveolar capillary
transfer, cardiac parameters, blood hemoglobin concentration,
barometric pressure, oxygen and carbon dioxide concentration in the
inhaled air, but the two most important factors in determining the
COHb level are the CO concentration and the duration of exposure.
The effects of different saturation blood COHb levels on healthy
adults are shown in table A1.
Table 1 - Health effects of COHb blood levels on healthy adults
% COHb Effects
03 - 0.7 Normal range in non-smokers due to endogenous
production
0.7 - 2.9 No proven physiological changes
2.9 - 4.5 Cardio-vascular changes in cardiac patients
4 - 6 Usual values observed in smokers, impairment in
psychomotor tests
7 - 10 Cardio-vascular changes in non-cardiac patients
(increased cardiac output and coronary blood flow)
10 - 20 Slight headache, weakness, potential burden on fetus
20 - 30 Severe headache, nausea, impairment in limb
movements
30 - 40 Severe headache. irritability, confusion, impairment in
visual acuity, nausea, muscular weakness, dizziness
40 -50 Convulsions and unconsciousness
60 - 70 Coma, collapse, death
% COHb Effects
Source: US Environmental Protection Agency 1984
The following symptoms are related to CO poisoning and are to be
discussed with ALL members of the household:
1. Mild Exposure: Slight headache, nausea, vomiting, fatigue (often
described as "Flu-like" symptoms).
2. Medium Exposure: Severe throbbing headache, drowsiness, fast
heart rate.
3. Extreme Exposure: Unconsciousness, convulsions, cardio
respiratory failure, death.
4. Many cases of reported CO poisoning indicate that while victims
are aware they are not well, they become so disordered they are
unable to save themselves by either exiting the building or calling
for assistance. Young children and household pets are typically
first affected.
B-2. Chronic Effects on High Risk Group
Individuals with coronary artery disease exposed to low levels of CO
showed reduced ability to exercise. The time of onset of exercise-induced
angina pectoris in such patients exposed to low levels of CO is reduced.
Carbon monoxide readily crosses the placental barrier and may endanger
the normal development of the fetus.
A number of high risk groups are particularly sensitive to the effects of
CO because of various organ impairments or specific changes,
mainly:
a. Those whose oxygen carrying capacity is decreased due to anemia
or other hemoglobin disorders.
b. Those with increased oxygen needs such as those encountered in
fever, hyperthyroidism or pregnancy.
c. Those with systematic hypoxia due to respiratory insufficiency.
d. Those with hearth disease and any vascular insufficiency, such as
cerebral ischaemia and peripheral vascular diseases.
B-3. Normal COHb levels
Under normal conditions all humans have low levels of COHb of
between 0.3% and 0.7% present within the body. These levels are
considered neither beneficial nor harmful.
B-4. Tobacco Smoking
Tobacco smokers are exposed to significant concentration of CO. In
cigarette smokers the COHb concentration varies between 5% - 9%
while heavy smokers it may exceed 10%.
Appendix C - Action to Take When Alarm Sounds
In case of harmful levels of CO gas is detected, your detector will go
into continuous full alarm, Try to take the following necessary actions
immediately:
1. Push the detector TEST switch to silence the alarm.
Warning: Never remove the battery to silence the alarm.
Removing the battery removes your protection!
2. Call your emergency service (tel. No. .............), or fire department
(tel. No. ............). (Please write the telephone numbers).
3. Immediately move to fresh air - outdoors or by opening
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 normal condition.
4. After following steps 1 - 3, if your alarm reactivates within 24 hours
period, repeat steps 1 - 3 and call qualified technician (Te. No.
........) to investigate for sources of CO gas from fuel burning
equipment and appliances, and inspect for proper operation of this
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 instructions, or contact the manufacturers directly,
for more information about CO safety and this equipment. Make
sure that motor vehicles are not, and have not been, operating in
an attached garage or adjacent to the residence.
!
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.
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.
Action to be taken after the problem has been corrected
Once the problem about the CO gas presence in the premises has
been corrected, the detector's alarm should be off. After waiting for 10
minutes, push the Test button, to verify that the detector is properly
working again.

Appendix D - Warnings and Limitations
This product is intended for use in ordinary indoor locations of family
living units. It is not designed to measure compliance with
Occupational Safety and Health Administration (OSHA) commercial
or industrial standards.
Caution: The detector will only indicate the presence of carbon
monoxide gas at the sensor. Carbon monoxide gas may be present in
other areas.
Individuals with medical problems may consider using warning
devices which provide audible and visual signals for carbon monoxide
concentrations under 30 ppm.
The alarm, including the sensor, is not to be located within 1.5m (5
feet) of any cooking appliance.
The 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 medical problem may consider
more sensitive detection devices.
The CO gas detector is not suitable as a smoke detector or fire
detector. This detector is not suitable to install in an hazardous
location as defined in National Electrical Code.
Carbon monoxide must reach the detector for proper performance of
CO gas detection.
The detector may not protect people who are at special risk from
carbon monoxide exposure by reason of age, pregnancy or medical
condition. In doubt, consult your medical practitioner.
CO detectors may wear out because they contain electronic parts that
fail at any time. Test your detector at least every week.
Instruct children never to play with the detector.
Never use detergents or other solvents to clean the detector.
Avoid spraying air fresheners, hair spray, paint or other aerosols near
the detector.
Do not paint the detector. Paint will seal the detectors vents and
interfere detecting CO gas.
Detailed information on conditions which can 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 situations.
2. Extended operation of unvented fuel burning devices (range,
oven, fireplace, etc.).
3. Temperature inversions which can trap exhaust gasses near the
ground.
4. Car idling in an open or closed attached garage, or near a home.
