When networking with the product host，this feature is used to associate other products. This has the effect that when the sensor detects
the CO leak, all devices associated with the sensor will receive the relevant reports and can be controlled by the sensor, e.g. the CO value,
alarm device etc.
This device supports three linkage groups: The group 1 is the lifeline group.
Linkage group 2 is assigned to the devices status - sending BASIC SET control frame to the associated devices having detected the CO
leak.
Linkage group 3 reports the detection's status to the associated device.
The maximum number of devices that can be added to the linkage group 1 is 5 number，linkagegroup2 or linkage group3 is 5 numbers.
This product will send a “BASIC SET(0xFF)” message to associated group, when press and release the test button(<2s) to check the
function; and this CO alarm will also send a “BASIC SET(0x00)” message to associated group, after end of test alarm(<10s). This CO alarm
will send a “BASIC SET(0xFF)” message to associated group, when this product is CO alarm (Conforms to EN 50291-1:2010+A1:2012
standard); and this product will also send a “BASIC SET(0x00)” message to associated group, when CO alarm is cleared.

Tips
1: Start up
After connecting the battery, all three LEDs light up briefly and the CO alarm confirms start-up with a beep.After power on, 30 seconds before
the green LED flash every 3 seconds, this is preheated state. 30 seconds later the green LED flashing every 30 seconds indicates the unit is
functioning properly. Power on time, if the yellow LED on 5 seconds, the Z-Wave module will be fault, but it is not affect the main function of
the alarm.
2: Normal operation
The POWER indicator (green LED) flashing every 30 seconds.
3: Fault warning
If the unit chirps once every 30 seconds, with FAULT indicator (yellow LED and beep) will be flash. It indicates the CO alarm is in malfunction
condition. That means your CO alarm has no detecting function and no respond CO.
Replace battery, if condition continues, the CO alarm has malfunctioned. Replace immediately. Please contact us to more service.
4: Low battery voltage warning
If the unit chirps twice every 30 seconds, with FAULT indicator (yellow LED and beep) will be flash. It indicates the battery is low. You need to
replace the battery.

6/ 8
NOTE: The unit will not protect against the risk of carbon monoxide poisoning when the battery has drained.
5: End of life warning
If the unit chirps 3 times every 30 seconds with FAULT indicator (yellow LED and beep) flash. It indicates end of life of CO alarm. You need
to immediately replace the CO alarm.
6: CO alarm warning
When the unit detects a dangerous level of CO, the unit will emit a loud alarm pattern. The alarm signal pattern is 4 quick beeps followed by
5 seconds of silence. This cycle repeats as long as a dangerous CO condition exists. The red alarm LED will flash the same pattern.
This signal will repeated until the alarm resets after dissipation of CO or the alarm signal is manually silenced.
7: CO alarm warning silence
If the unit is under the CO alarm warning, enable the TEST&SILENCE button, it will come into silence status for 5 minutes, and ALARM
indicator (red LED) still keep flashing.
Note: The alarm signal will re-energized within 5 minutes from the time the TEST&SILENCE button is operated if the concentration
of CO surrounding the alarm remains at 45ppm or greater.
8: Human alarm sounds
If the unit come into the status of CO alarm warning, the unit will start in a lower volume (<80dB) for around 10 seconds, then issuing a normal
volume (>85dB). It will avoid people to be scared suddenly by a very loud alarm sound.

What to do if the alarm sounds
WARNING! –Action of this device indicates the presence of dangerous levels of CO! CO can be fatal! If the alarm sounds:
If a carbon monoxide apparatus initiates an alarm signal it is recommended that the following actions are taken in the order given:
1: Keep calm and open all doors and windows to increase the rate of ventilation, but see also item a) below. Stop using all fuel-burning
appliances and ensure, if possible, that they are turned off, e.g. for gas appliances, isolate the emergency control valve;
2: If the alarm continues to be activated, then evacuate the premises. Leave the doors and windows open, and only re-enter the building
when the alarm has stopped. In multi-occupancy and multi-storey premises, ensure that all the occupants are alerted to the risk;
3: Get medical help for anyone suffering the effects of carbon monoxide poisoning, see point Health effects of carbon monoxide (CO)
(Table A), and advise that carbon monoxide inhalation is suspected;
4: Telephone the appropriate appliance servicing and/or maintenance agency or, when necessary, the relevant fuel supplier on their
emergency number or the national Gas Emergency Service Provider, if appropriate, so that the source of carbon monoxide emissions can

WARNING: This apparatus is designed to protect individuals from the acute effects of carbon monoxide exposure. It will not fully
safeguard individuals with specific medical conditions. If in doubt consult a medical practitioner.
Health effects of carbon monoxide (CO)
1: Toxic effects
Carbon monoxide (CO) is a colourless, odourless, non-irritating gas classified as a chemical asphyxiant and 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 reversibly bound with haemoglobin as
carboxyhaemoglobin (COHb), however, a minute amount is present in the plasma.The affinity of haemoglobin for CO is over 200 times its
affinity for oxygen. This reduces the oxygen carrying capacity of the blood, and has an effect on the dissociation of oxyhaemoglobin, which
further reduces the oxygen supply to the tissues. CO is chemically unchanged in the body, and is eliminated in expired air. The elimination is
determined by the same factors that applied during absorption. The half-life while breathing room air is 2 h - 6,5 h depending on the initial
COHb level.
If the CO level in the inhaled air is constant, the level of COHb in the blood will approach an equilibrium (saturation) 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 haemoglobin 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.

2: Chronic effects on high risk groups
Individuals with coronary artery disease exposed to low levels of CO show reduced ability to exercise and 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 foetus.
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 anaemia or other haemoglobin disorders;
b: Those with increased oxygen needs such as those encountered in fever, hyperthyroidism or pregnancy;
c: Those with systemic hypoxia due to respiratory insufficiency;
d: Those with heart disease and any vascular insufficiency.
3: Normal COHb levels:
Under normal conditions, humans typically have low levels of COHb of between 0,3 % and 0,7 % present within the body. These levels are
considered neither beneficial nor harmful.
4: Tobacco smoking
Tobacco smokers are exposed to significant concentrations of CO. In cigarette smokers, the COHb concentration varies between 5 % - 9 %,
while heavy cigar smokers may exceed 10 %.
WARNING!-Exposure to high levels of carbon monoxide can be fatal or cause permanent damage and disabilities.
WARNING : The apparatus may not prevent the chronic effects of carbon monoxide exposure, and that the apparatus will not fully
safeguard individuals at special risk.
