COG 01 has two separate built-in sensors to detect the presence of carbon-monoxide, and of other common household gases such as natural gas, methane (CH4), as well as propane
(C3H8) and butane (C4H10), which are commonly distributed in cylinders. For higher reliability, both the CO sensor and the circuitry include a self-testing mechanism. The sensor’s LED
lights signal all detected situations. The alarm always sounds before the gas’s concentration reaches a lethal level.
Locating the device
The sensors can detect the presence of carbon-monoxide, natural gas (methane), propane and butane. When locating the sensor, the key thing to consider is what sort of danger you are
trying to protect yourself from.
The density of carbon monoxide is similar to that of warm air, therefore the ideal height where the sensor should be located is at least 1.5 meters above the floor level, and it should be at
least 1.8 meters away from the supervised burning device. Do not place the sensor closer than 30 cm to any corner. The sensor will only measure a realistic value for the room if you
observe the above parameters when locating it.
The sensor should be placed close to appliances that produce exhaust. Whenever any material is burnt in a suboptimal way, there is a potential emergency because carbon-monoxide
may be produced:
- gas stoves, gas cookers, gas heaters, gas water heaters, gas furnaces, fireplaces, oil heaters, wood or coal fueled heaters, garden stoves with grill, cigarette smoke, car exhaust
pipes etc.
If a chimney is blocked or under unfavorable wind conditions, the exhaust of burners may be channeled back indoors. Carbon-monoxide can accumulate near the burners connected to
the chimney, and also near the vent or service door at the bottom of the chimney. A similar situation can build up near the fans located above gas stoves. As modern, perfectly isolated
doors and windows become increasingly wide-spread, homes lose their previous natural ventilation.
Attention! The sensor can only detect dangerous carbon-monoxide levels in the particular room where it is located. Carbon-monoxide, however, may still be present in other places.
The density of household gases varies on a large scale. You need to decide which gas you wish to detect, and place the sensor above the floor or below the ceiling accordingly. In both
bases, the sensor’s nearest side should be 30 centimeters away from the chosen surface (floor or ceiling). Natural gas is lighter than air, which means it accumulates in higher places;
therefore, to detect natural gas, place the sensor below the ceiling. Propane-butane is heavier then air, therefore to detect propane-butane, place the sensor above the floor. In both
cases, it is best to mount the sensor on a wall.
When locating the device, make sure you observe the following:
For reliable operation, avoid the following environmental conditions:

- temperatures below -10 C or above 50 C;
- wet, humid, dusty, dirty or polluted air;
- areas behind a curtain or piece of furniture;
- close to cooling or heating devices, behind fans;
- in the way of airflow, e.g., next to an open door or window;
- any location where smoke or steam may naturally be present (e.g., near the stove, burner or electric kettle in the kitchen); close to a smoking area;
- in locations with high humidity (e.g., immediately above a sink, or next to a bathtub, shower cabin, washing machine etc.);
- near the car’s exhaust in a garage.
Installation
1. Choose where you wish to locate the device as described above.
2. Fasten the wall mount to the desired location.
3. Slide the sensor onto the wall mount.
4. Connect the sensor to the power network. The product will emit a beep and the power on LED (2) will start to flash (lit up for 3 seconds, then turned off for 1
second). This indicates that the product is working correctly. After 3 to 5 minutes, the product is ready for use.
Testing and self-diagnostics
It is recommended to test the carbon-monoxide sensor when installing the product; then repeat the test once every week. Press and hold the CO TEST button (6) for
1-2 seconds. The carbon-monoxide indicator LED (3) will flash up 3 times in read, and the product will emit 3 short beeps.
It is not possible to test the gas sensor by pressing a button; for this purpose use a device with a small amount of gas (e.g., an unlit lighter). Hold the lighter 5
centimeters away from the gas sensor’s hole (5), and let gas enter through the hole for a few seconds. The product will emit a beep and the gas indicator
LED (4) will start to flash. This signal will last as long as the product detects the presence of gas. When that is no longer the case, the sensor goes back to
normal mode.
Do not test the product in any other way (e.g., by blowing smoke directly into it) because that can damage the sensor. Under proper use, the
sensor’s expected lifetime is 5 years.
