Detector carbon monoxide detector buzzer no relay, 220vac odorless gas gas co detectors carbon monoxide detector gas co detector

Dimension 125x73x35mm . Weight 330gr
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 combustor .

It detects CO gas and be both a store, a house or an apartment. This detector is designed for installation in ceiling or wall ( at a height of 1.5 meters). A single sensor CO gas can cover an area of approximately 60m2 . Upon detection of CO gas detector beep that will save your life . Fully self contained and enjoying a very good quality / price ratio, the DCO2202 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 PEOPLE FOR WHICH EXPOSURE TO CARBON MONOXIDE HAZARD THIS PARTICULAR BECAUSE OF THEIR AGE OR THEIR HEALTH STATUS . SUCH PERSONS MUST CONSIDER USE OF DEVICES
WARNING VISUAL AND AUDIBLE FOR CONCENTRATIONS OF CARBON MONOXIDE NOT EXCEEDING 30 PPM . IF IN DOUBT , CONSULT YOUR DOCTOR . THIS CARBON MONOXIDE DETECTOR DOES NOT REPLACE THE
FIRE ALARM DETECTORS GAS FUELS .
This carbon monoxide alarm device is designed to detect the sources generated by combustion of any gas , 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 dangerous amount of carbon monoxide may occur in the following cases :
1 . Presence of a combustion device defective or improperly maintained .
2 . Drain tube partially or totally plugged.
3 . Poor ventilation.
The following conditions may lead to cases of transient presence of carbon monoxide :
1 . Excessive spillage or reverse discharge apparatus for combustion , caused by environmental conditions , such as:
i . Wind direction and / or air flow , including wind. Heavy air in the pipes ( cold damp air with extended periods between cycles) .
ii . Negative pressure differential due to the use of fans discharge .
iii . Simultaneous use of multiple devices sharing a combustion air volume limited local .
iv . Detachment fittings Pipes ( dryer, water heater or boiler ) .
v . Obstructions in the pressure lines or forcemains non-traditional form, which can amplify the above situations.
When the alarm is triggered, the buzzer sounds. Monoxide Detector!
This device can automatically detect interior carbon monoxide. When CO reaches a certain level, the device will give visual and audio alarm to avoid poisoning or even serious accidents resulted from CO.
GD Series gas leak alarm is a kind of wall-hung household gas alarm designed to detect the concentration of combustible and toxic gases or vapors. It provide a visual and audible signals when the gas concentration reaches pressing level, remind you take prompt favorable action, you may start up other link equipment, ventilate gas or shut off gas supply to avoid Fire, explosion, suffocation, and other evil accident. The alarms are available for liquefied petroleum gas (LPG), natural gas (Methane), propane, Hydrogen, town gas, smoke, etc. They are not only installed at home, but also used at any other potentially hazardous areaes.
MCU control, Reliable without false alarming
Locale sound and light alarming, Drive Long-distance Alarming System Ventilate good air circulation or shut off gas supply link equipment

Operating Manual
1. Fix gas alarm on the wall or Roof near the gas cooker or other sources within 2-4m interval. According to gas sources Character, Choose alarm location as follows:
LPG: Fix it within 0.3 meters above the ground (LPG is heavier than Air)
Coal Gas, Natural Gas: Fix it within 0.3 meters below the Roof(Combustible gas is lighter than Air)
Avoid such installation: Windows with strong wind, Exit, water fog and drop place; easy polluted or high temperature environment near Oven, covering around.
2. Connect the Power supply, (if need ventilate fax, electrovalve other link equipment, please connect corresponding circuit firstly.) Preheat the alarm 1 min, the power on green LED, WARN-UP yellow LED both light, the alarm without detecting function. 1 MIN later, The warm-up LED black out, the alarm enter in to detecting status.
3. If the flammable gas in the air reaches the present alarming concentration, the alarm enter into alarming status, the Alarm red LED light or flash, the buzzer give sound alarming, drive the relay or valve shut off gas supply, If the alarm connect the ventilation fan or other relative electronics, it also open automatically; At the same time, please cut off gas supply promptly, open the window, ask professional worker to remove the fault, The alarm with gas cut off valve type shall output one close pulse signal.
If the yellow(Fault) LED light, it means the gas alarm has fault itself, please contact distributor to find solution.
Operating Button:
W-UP: Stop 1 MIN preheating when press it, the Warm-up Yellow LED black out, the alarm enter into detecting status.
RELAY: Relay control button, during the detector status, press this button, you can control relay work by hand.
