Carbon monoxide is a dangerous, colorless, odorless gas. And the air circulation in the basement and underground parking garage is not good, which can easily lead to excessive concentration of harmful gases such as carbon monoxide, harming human body. Therefore, it is necessary to install a carbon monoxide detector in the basement or underground parking garage to monitor the CO concentration in real time to prevent people from hypoxia poisoning or carbon monoxide poisoning. For buildings with underground parking garages, it is also necessary to install exhaust equipment linked with carbon monoxide detectors. When carbon monoxide exceeds a certain level, the detector will alarm and the exhaust system will be activated right away.

Where Does CO Come From?
Car exhaust fumes
Gas/oil furnaces
Gas space heaters
Gas stoves
Hot water heaters
Lawn mowers
Pilot lights
Tobacco smoke
Wood-burning stoves

Where to Install Carbon Monoxide Detector
On every floor, including the basement.
Near sleeping areas within 10 feet of your bedroom doors
Near or over any attached garage
You should install CO alarms at least 5 feet over the floor, as CO is lighter than air and rises. You can also install the CO alarm on a ceiling if you prefer.

Basement Installation Requirements
1. Install the carbon monoxide detector on a wall or high up near the ceiling. And when installing a battery-operated detector, you should install it on the wall below the ceiling, not on the ceiling. Many battery-operated detectors prefer wall mounting, so be sure to check the manufacturer's instructions.
2. Before installing a carbon monoxide detector, you need to decide the installation location by testing the warning alarm of the detector, make sure that the alarm can be heard in other places.
3. Do not install the carbon monoxide detector within 5m of any heating or cooking equipment such as a stove or dryer. If doing so, it may cause false alarms.
4. Do not install carbon monoxide detectors where windows are often opened.

Underground Parking Garage Installation Requirements
1. The carbon monoxide detector installed in the underground parking garage should be installed 1.5m above the ground, and should adopt the wall-mounted method, installed in the air circulation position.
2. It is recommended to divide the zone according to fire prevention, area size, etc. Normally, every 200-300m should install a carbon monoxide detector.
3. The carbon monoxide detector should be installed in a place without shock, vibration, and strong electromagnetic field interference, and there should be no less than 0.3m of clean air around.
4. The installation and wiring of the carbon monoxide detector should be carried out in accordance with the requirements of the manufacturer, and should comply with the relevant regulations on the installation and wiring of explosion-proof instruments.

According to the "Green Building Evaluation Standard", the underground parking garage needs to be equipped with a carbon monoxide concentration monitoring device linked to the exhaust system. It is for:
1. It is a consideration of safety, ensuring the carbon monoxide concentration in the garage is at a normal value.
2. Automatically judge whether to activate the exhaust function according to the concentration of carbon monoxide in the underground parking garage, saving energy and avoiding unnecessary waste.
3. According to the toxicity of carbon monoxide, we know that 50ppm is the maximum limit that an adult can bear within eight hours. It is recommended that the alarm value of carbon monoxide detectors be set at 30ppm. When the concentration value exceeds 30ppm, the detector will automatically alarm and activate the exhaust system.

How to Install Carbon Monoxide Detector

1. Read the manufacturer’s installation manual carefully.

2. Choose a drill bit that’s a little bit smaller than the wall anchors.

3. Mark the screw holes of the mounting base.

4. Tap the screw anchors into the wall with a hammer.

5. Put the screws in the wall.

6. Line up the mounting base with the screws.

7. According to the CO detector’s user manual, connect the wires or install the batteries (Follow the CO type)

8. Screw the CO detector into the screws.

9. Tighten the screws with a screwdriver.

10. Mount the alarm onto its base.

Maintain Carbon Monoxide Detector

After installing the carbon monoxide detector, you should do some maintenance keep it normal.

1. Test the carbon monoxide detector at least once a month. Most of them just need to press a button to test the alarm and the battery.

2. Replace the battery every 6 months even if you don’t hear the warning beep. If you are using a lithium-ion battery, replace the battery every 10 years.

3. Vacuum every detector once a year to clean the dust or particles in it.

4. Check the date of manufacture of each device regularly and replace them when expired

A fire hose is a highly pressurized hose that is used to bring water to the fire. It may also transport flame retardants. Fire hoses can be attached to either a fire engine or a fire hydrant, and the pressure is between 800 and 2000 kPa. For reasons of fire safety, it's quite important to have a fire hose inspection as well as all fire protection equipment tested.  If, during a fire emergency, the fire hose fails it could have disastrous results.

Fixed Temperature Waterproof Heat Detector, the detector uses a bi-metallic strip to sense temperature change, therefore consuming minimal standby current and providing high reliability.
The Detector is particularly suited to environments, which are exposed to high levels of condensation or are hosed down. The detector has a wide operating margin allowing it to respond to both slow and fast increases in temperature; it can also sense temperature reliably in a horizontal or vertical position.
