2,Install

2.1 Recommended installation area

It is recommended to install alarms near your bedroom and living area, or where you think carbon monoxide is likely to leak

If the alarm is mounted on a wall, it should be higher than the height of any door or window, but at least 150mm from the ceiling panel. If the alarm is mounted on the ceiling, it should be at least 300mm from any wall and at least 1m-3m from the potential air source. If there is an isolator in the room, the alarm should be placed on the same side as the potential source of air. In a room with a pitched ceiling, the alarm should be located on the high side of the room and very close to the area where the occupant is breathing frequently.

Ideally, it is suggested that in each room with a fuel use utensils with an alarm, but if the alarm is limited, when determining the position to consider the following: if the bedroom has a burner, the need to install an alarm system in the bedroom, if the room for the chimney or ordinary flue type burner, you need to install an alarm system in the room. If in a bedroom/living room, the alarm should be kept as far away from cooking utensils as possible. If in an infrequently used room, such as a boiler room, the alarm should be installed outside the room so that it is easy to hear the alarm sound.

Do not install carbon monoxide alarms too high in places where there is no ventilation, such as on vaulted ceilings or pointy roofs.

Do not install in areas with temperatures below 0 ° C or above 50 ° C, including rooms, attics, corridors and garages. Extreme temperatures will affect the sensitivity of the carbon monoxide gas alarm.

Don't block the alarm vent. Place the alarm in an area that won't be blocked by curtains, furniture, or other objects.

Do not install carbon monoxide alarms too close to the burner, which may cause frequent alarms and noise pollution.

Do not install near doors or Windows to the outdoors, near fresh air vents or any other well-ventilated area. Fast circulating air from fans or fresh air from outdoors can affect the response to an alarm.

2.3 Installation method

The alarm can be mounted on the roof or on the wall. After selecting the installation position, draw the installation hole on the installation bracket, punch holes on the drawn mark, insert the rubber plug into the hole, and install and fix the installation bracket with self-tapping screw. If it is not convenient to punch and fix, you can also use back glue to fix.

Align the hook slot on the rear panel of the alarm with the buckle on the mounting base, and fasten the alarm and the mounting base from top to bottom to finish the installation.

2.4 Battery installation and replacement

Push the alarm upward and remove it from the mounting bracket. The battery compartment can be seen, and the battery can be replaced by taking out the battery. The battery compartment has anti-installation device and anti-freeze device. After the battery is installed, the starting prompt will appear and the LCD screen will be lit. If it does not appear, there will be no power access. The capacity and voltage of the battery should be consistent with the voltage marked by the alarm.

2.5 Wiring instructions

In the figure above, there are two control outputs, one for connecting the exhaust fan and the other for cutting off the air source.

The control output port connected to the exhaust fan can be connected to the maximum 220V/1A size of the exhaust fan.

The power adapter interface is used to supply power to the device and supports access to the 5V/2A power adapter.

3,Safety knowledge of CARBON monoxide

3.1 Introduction to Carbon Monoxide

Carbon monoxide will enter the human body and the hemoglobin in the blood binding, because the CO and hemoglobin binding ability is far stronger than the binding ability of oxygen and hemoglobin, and then make the number of hemoglobin can be bound with oxygen sharply reduced, thus causing the occurrence of oxygen deprivation in the body tissues, leading to human asphyxia death. So carbon monoxide is toxic. Carbon monoxide is a colorless, odorless, odorless gas, so it is easy to ignore and cause poisoning. Common below the circumstance that sees domestic bedroom ventilation is poor, the gas that coal furnace produces or liquefied gas conduit leaks gas or the carbon monoxide in industrial production gas and mine is inhaled and cause poison.

3.2 Hazards of carbon monoxide

  • mild, mild headache, weakness, chest tightness
  • is serious, serious end, nausea, limb weakness
  • Severe headache, irritability, nausea, mental disorder, impaired vision, muscle weakness, dizziness
  • extremely serious, convulsion, unconsciousness, coma, collapse and die

 

3.3 Carbon monoxide safety precaution

Open indoor doors and Windows frequently, keep indoor air circulation, install carbon monoxide alarm at appropriate locations, monitor the concentration of carbon monoxide in real time, and remind the crowd to leave the dangerous area when the alarm goes off, so as to prevent carbon monoxide poisoning.

3.4 Alarm processing

When the air environment, the carbon monoxide density exceeds the alarm setting density, alarm will be issued a warning voice and light alarm signal, at this time should do the following processing: quickly close the valve, open the doors and Windows to keep the indoor air circulation, leave the danger zone, if the alarm alarm, please inform relevant departments or professional processing, such as checking is alarm false positives, the user check alarm installation location.
