UMWELT:

The most common carbon monoxide sources are faulty gas devices used for heating and cooking, vehicles running in an adjacent garage, clogged chimneys or smoke ducts, portable fuel stoves, fireplaces, fuel-powered tools and the use of open fire in an enclosed space.

All fuel types can produce carbon monoxide.

Symptoms of carbon monoxide poisoning are dizziness, fatigue, weakness, headaches, nausea, vomiting, sleepiness and confusion.

Everybody is sensitive to the dangers of carbon monoxide, experts agree however that unborn babies, small children, pregnant women, elderly people and persons with heart or breathing problems have the highest risk of serious or even fatal injuries. Every year an authorized installer must inspect and clean your heating system, vents, chimney and smoke ducts.

WARNING! – When the alarm sounds, possible harmful carbon monoxide levels are present! Carbon monoxide can be deadly!

The detector must be installed by a competent person.

CO concentration	Period of inhaling and symptoms
50PPM	The maximum concentration a healthy adult can withstand in 8 hours.
200PPM	After 2-3 hours, mild headache, sensations of weakness, dizziness, nausea.
400PPM	Within 1-2 hours, ache in forehead; after 3 hours, life-threatening.
800PPM	Within 45 mins, dizziness, nausea, convulsions; Loss of consciousness within 2 hours; Fatal within 2-3 hours.
1600PPM	Within 20 mins, headache, dizziness, nausea; Fatal within 1 hour.
3200PPM	Within 5-10 mins, headache, dizziness, nausea; Fatal within 25-30 mins.
6400PPM	Within 1-2 min, headache, dizziness, nausea; Fatal within 10-15 mins.
12800PPM	Fatal within 1-3 min.

ATTENTION: THE CO DETECTOR ONLY SOUNDS THE ALARM WHEN CARBON MONOXIDE IS PRESENT AT ITS SENSOR. THEREFORE, IT'S POSSIBLE FOR CARBON MONOXIDE TO BE PRESENT ELSEWHERE AND THE ALARM DOESN'T SOUND.

This CO detector is not a replacement for smoke, fire or other detectors.

This detector cannot protect people with special medical conditions and might not prevent any chronic health effects of carbon monoxide on the body. This is not a replacement for the correct installation, use and periodic maintenance of combustion equipment, nor adequate ventilation of spaces in which these devices are being used.

RECOMMENDED POSITIONING FOR THE COA-28:

• Install the CO detector in a bedroom, a hallway near the bedroom or the area near a combustion device (boiler, water heater, gas stove, etc.). Check whether the alarm can be heard inside bedrooms.
- In houses with multiple floors, it's recommended to install a CO detector on each floor.
- Install the CO detector at least 2 meters away from combustion devices, within the air flow from the combustion device. In the case of smaller spaces ( <4m^3 ), the detector should be installed outside these spaces.
- Install the CO detector in spaces without open combustion devices, preferably 1.50m above the floor and outside spaces without air flow. In bedrooms, install the detector at ‘face height while sleeping’.
• Install the detector on a spot where the weekly check can be performed easily.

AVOID THE FOLLOWING PLACES FOR INSTALLATION:

• Never install the CO detector in spaces without air flow, such as roof ridges, arched ceilings or front roofs.
• Never install the CO detector in the turbulent air from ceiling fans, nor place it near vents with fresh air or close to doors and windows opening to the outside.
• Keep the CO detector away from extremely dusty, dirty or greasy spaces such as kitchens, garages and heating spaces < 4m^3 or pantries. Dust, grease and household chemicals can affect the sensor.
  • Install the CO detector at least 0.5 meters away from gas discharge lamps (halogen) because of electronic interferences that can lead to false alarms.
• Keep the CO detector away from humid and wet spaces. Do not use spray cans near the CO detector.
• Never install the CO detector in spaces with temperatures lower than 0°C or higher than 45°C, and the humidity higher than 90%RH.
• Never install the CO detector behind curtains or furniture. Carbon monoxide must be able to reach the sensor to ensure the sensor can properly detect carbon monoxide levels. NEVER place the CO detector flat on a table or similar surface.

INSTALLATION INFORMATION:

Install the mounting plate on a suitable spot using plugs and screws, preferably on the wall. Insert the batteries into the detector. 1. First, turn the securing pins inward and 2. insert the batteries. All three LEDs will briefly illuminate, the detector will emit a short beep tone and the display briefly lights up. Now install the detector onto the mounting place and press the detector down until correctly fastened. You can perform the first test by briefly pressing the test button, see also paragraph "Testing and reset".

USE:

The CO detector starts functioning after installing the batteries (High Energy Alkaline batteries 1.5V AA - LR6) and mounting the CO detector on the wall. The unit can only be placed onto the mounting plate with the batteries in place. The green “POWER” LED will flash every 45 seconds to indicate that the detector is working. Every 45 seconds, the display will show the following cyclic data: the temperature (indicative) in °Celsius (provided the CO levels are lower than 25PPM) and the CO level. The battery capacity monitor indicates the battery capacity. When this battery capacity monitor indicates an empty battery or the detector emits a short beep tone every minute, you should replace the batteries as soon as possible. When these warnings start, the detector will continue to function correctly for at least 7 days. The display shows the measured CO value in PPM. The detector will indicate OPPM for levels between OPPM and 25PPM. When between 25PPM and 550PPM ±10%, the measured CO value will be indicated. When higher than 550PPM, the display will show Hco. The table below shows when the detector will sound the alarm.

CO concentration	NO ALARM for	ALARM for
30PPM	120 min.	-
50PPM	60 min.	90 min.
100PPM	10 min.	40 min.
300PPM	-	3 min.

In accordance to the EN50291 standard.

When the alarm sounds, it must turn off within 6 seconds after moving the detector to a space with a CO concentration below 40PPM.

Every 2 minutes, the detector will automatically perform an error check.

BATTERY INFORMATION INDICATION:

Every 45 seconds, the battery is checked automatically.

The green power LED will flash every 45 seconds for as long as the battery power is higher than 3.5 Volts. This means the battery capacity is sufficient. As soon as the battery power drops below 3.5 Volts, a beep tone will be emitted when the green LED flashes briefly. At that time, please replace the batteries as soon as possible.

The display also shows a battery capacity monitor:

Full
Half
Low
Empty

When empty batteries are indicated, the batteries should be replaced as soon as possible.

Use High Energy Alkaline batteries (3 x LR6 / 1.5V AA).

Remark: Rechargeable batteries are not suitable.

With both the supplied batteries and most A brand batteries on the market, it will take approximately one year before the batteries run empty.

TESTING AND RESET:

Testing:

When the CO detector is working under normal conditions, the sensor and siren should be tested at least every month by pressing the “TEST”/MENU” button.

Press the “TEST/MENU” button. The “POWER”, “FAULT” and “ALARM” LEDs will illuminate. The detector will then emit 4 beeps while the red “ALARM” LED flashes 4 times. When the display shows - everything is in order.

If the sensor detects an error, the yellow "FAULT" LED will flash 2 times while 2 beep tones are emitted. The display will now show Err

Reset:

The alarm can sometimes activate because of environmental influences, for example due to smoke with certain carbon monoxide concentrations or other chemical gases that are not life-threatening. In this case, you can press the “TEST/MENU” button provided that the CO value is below 150PPM. The alarm will stop and the detector immediately starts checking the gas again. If the concentration is above 150PPM, it’ll be impossible to stop the alarm. The red LED continues flashing, but the siren will stop for 5 minutes. If the concentration is still above 150PPM after those 5 minutes, the alarm will continue.

ALARM DISPLAY AT ACTIVE ALARM:

When there's an active alarm, the red "ALARM" LED will illuminate, 4 beep tones are emitted continuously and the display will illuminate. When the carbon monoxide concentration drops below 40PPM, the alarm will stop.

SCREEN DISPLAY:

The LCD display shows the concentration of carbon monoxide. The value has a range of 25 - 550PPM ±10%. When the concentration is above 550PPM, the text Hco appears which means a high carbon monoxide concentration and therefore a high risk. All people and animals should leave the area as soon as possible.

SENSOR FAULT INSPECTION:

When the CO detector is active and functions in standby mode, only the carbon monoxide is automatically tested every 2 minutes to verify its proper working.

You can use the “TEST/MENU” button to manually test both the carbon monoxide sensor and the alarm signal.

When the detector identifies an error, it will continuously emit 2 beep tones and, in addition to this sound, the yellow “FAULT” LED will illuminate.

The display will also light up and show Err.

When an error is detected, the detector will check every 10 seconds whether the error is still present until it disappears.

When the detector rapports an error, this could be because of broken circuitry, a faulty sensor or a permanent defect due to faulty electronic parts. Volatile chemical gases such as alcohol can also be the cause for error detection. Such errors can be corrected switching the detector off and leave it in fresh air for 24 hours. This will restore the sensor.

If the error is not cleared after these 24 hours, the detector is faulty and should be replaced.

Don't repair the detector yourself, but have it repaired by the importer.

The following substances and gases can cause false alarms or permanently damage the detector: methane, propane, iso-butane, ethylene, ethanol, alcohol, iso-propanol, benzene, toluene, acid, ether, hydrogen, hepatic gas, sulphur dioxide, aerosol, propellant, alcohol preparation, paint, thinner, dissolvent, bonding agents, shampoo, aftershave balm, perfume, car exhaust (cold start) and certain cleaning agents. When the alarm is contaminated and damaged by high concentrations of chemical gases, the sensor could be affected. This will lead to a temporary error or permanent damage. When the alarm sounds and you can smell a chemical gas, this could be the reason. Carbon monoxide is a colourless and odourless gas. Chemical gases do have an odour. If the detector sounds the alarm because of a chemical gas, please switch it off and leave it in fresh air for 30 minutes. If the detector remains in alarm mode or the concentration shown on the LCD screen increases or changes only slowly, it means that the alarm is contaminated by a chemical gas. In this case, remove the batteries and leave the detector in fresh air for a longer period of time to restore the sensor. If the sensor is still not functioning properly after a week in the fresh air, the sensor is faulty and the detector can no longer be used.

ALARM:

When the CO detector sounds the alarm, carbon monoxide (CO) might be present which can be fatal. Therefore, do never ignore this alarm.

What to do when the alarm sounds:

1 Open doors and windows and immediately do outside into the fresh air. Check whether everybody has left the building.
2 Call an official installer to inspect the correct functioning and state of maintenance of the combustion source (gas or oil powered equipment) that could be the cause for the CO alarm. Only enter the building again after the cause has been resolved and the building has been well ventilated.

The alarm sound can be switched off by pressing the TEST/MENU button (<150PPM).

LED INDICATION:

Red LED Alarm, carbon monoxide present

Green LED Normal functioning, flashes every 45 seconds

Yellow LED Sensor problem

SENSOR REPLACEMENT:

The sensor has a lifespan of 7 years. After 7 years you should replace the entire product because the sensor cannot be replaced.

If the yellow LED illuminates within these 7 years, even though you've reconnected or replaced the batteries, please refer to the paragraph "Sensor inspection" on page 7.

If the red LED switches on, the yellow “FAULT” LED illuminates 2x and 2 beep tones are emitted while End appears in the display, the entire product should be replaced.

MAINTENACE:

To keep your CO detector in proper working order, please follow these easy steps:

• Check whether the alarm is working properly by pressing the test button every week.
• Clean the CO detector with a vacuum cleaner or with a soft cloth or brush once every month to remove excess dust.
• Check whether the batteries are damaged, exhausted or corroded.
• Explain to children that they should not play with the CO detector and make sure they are aware of the dangers of carbon monoxide poisoning.
• Never use cleaning agents or other solutions to clean the CO detector.
• Never use air fresheners, hair spray or other aerosols near the CO detector.
• Don't paint the CO detector. Paint covers the vents preventing the sensor from detecting CO.
• Never disassemble, repair or modify the product yourself; there's a high risk that it will no longer function correctly or reliably.
