A perfect item for protecting your family from the dangers of carbon monoxide.

Advanced level of protection, easy to read with the digital display, even in low light conditions.

Displays the level of carbon monoxide the unit is sensing.

Green LED: Flashes every 30 seconds to indicate the unit is operating properly. The green LED will also flash before CO reading is taken and when any button is pressed.

Red LED : When a dangerous level of carbon monoxide is detected the red LED will pulse and a loud alarm pattern will sound. The carbon monoxide alarm pattern is 4 short beeps, followed by 5 seconds of silence, followed by 4 short beeps with a corresponding red LED flash. This cycle will continue for 4 minutes and then change to 1 cycle every minute until the device is reset or the CO is eliminated.

Test/Reset button is designed for weekly testing if it works properly and reset the unit during CO alarm.

Alerts users when batteries needs to be replaced.

This alarm is highly recommended to be mounted on a wall surface.

Compact, lightweight & easy to operate.

Carbon monoxide detector with alarm Wireless : easy to install.

Carbon monoxide is produced by incomplete combustion of fuels such as wood, coal, oil, natural gas, propane .

This is an extremely dangerous gas because it is invisible and odorless.

With a detector , you are immediately aware of the presence of carbon monoxide.

For maximum protection , place one at each device combustion.Il detects CO gas and also be in a shop , a house or an apartment.

The detector is designed for installation on the ceiling or wall ( at a height of 1.5 meters).
One sensor CO gas can cover an area of approximately 60m2 . Upon detection of CO gas , the detector will beep that will save your life .

Fully autonomous and enjoying a good quality / price ratio, the DCO9 is essential in all the places where the CO gas is present .
Carbon monoxide (CO) is a highly toxic gas emitted during the combustion of fuels.
Because it is invisible and odorless, it is very difficult to detect.

Warning : Enabling your carbon monoxide detector indicates the presence of carbon monoxide ( co) , a gas that kills.
This carbon monoxide detector may not protect pregnant women or persons for whom exposure to carbon monoxide is particularly dangerous because of their age or state of health .
These people should use visual and audible warning devices for carbon monoxide concentrations not exceeding 30 ppm. If in doubt , consult your doctor.
This carbon monoxide detector does not replace fire alarms or combustible gas detectors .
This carbon monoxide alarm device is designed to detect emitted by any sources of combustion gases, including wood, coal, oil and gas.

Under normal conditions , the amount of carbon monoxide emitted in well ventilated areas, where well-maintained equipment is not dangerous.

The presence of a quantity of dangerous carbon monoxide can occur in the following cases :

1.Présence a combustion device defective or poorly maintained.
2 . Drain pipe partially or completely closed .
3 . Poor ventilation.

The following conditions can lead to cases of transient presence of carbon monoxide :
- Excessive Spills or discharge reversal combustion appliances , caused by environmental conditions , such as:
- Wind direction and / or air flow , including wind. Heavy air in the pipes ( cold damp air with extended periods between cycles) .
Negative differential - pressure due to the use of fans discharge .
Using multiple - simultaneous combustion devices sharing a limited amount of air in the premises.
Detachment - discharge pipe fittings ( dryer, water heater or boiler ) .
- Obstruction in discharge pipes or discharge pipes in non-traditional form, which can amplify the above situations.
When the alarm is triggered, the buzzer sounds.

Detection limit: CO 150 + / - 50 ppm.
Loudness of the alarm: 85dB
