Why do we need to install smoke?
The installation of high-quality, independent, automatic smoke alarms is primarily intended to prevent fire incidents, reduce property damage and protect lives. As the number of users of smoke alarms continues to increase, the number of deaths due to residential fires continues to decline. According to a report from the National Fire Protection Association of the United States, once a fire has been installed in a residential building equipped with a recommended number of smoke alarms, the chances of escape for a person in the house will be 50% higher than that of an unmounted home.
What occasions need to install a sense of independent smoke?
Internet cafes, shops, warehouses, small hotels and student dormitories with a construction area of ​​less than 300 square meters, hotel and factory staff quarters, rental houses, nursing homes, and residential houses.
What is the sense of independent smoke?
Full name for independent smoke: a stand-alone photo-electric smoke detection alarm, referred to as an independent smoke detector or an independent smoke detector, or simply an independent smoke sensor. Its working principle is that the smoke detection alarm can be sensed when the concentration of smoke in the air reaches a certain level. This generates an alarm signal so that the owner can quickly take action.
What type of smoke is more suitable for home use?
Photoelectric smoke detectors are less sensitive to tiny smoke particles, so they do not produce false alarms for cooking smoke particles; they sense the larger smoke particles faster because smoldering (such as cigarette butts lighting sofas) Slightly larger smoke particles in the air. Under normal circumstances, photoelectric smoke alarm will not respond to smoking smoke, unless the smoke produced is very strong, for example, directly into the smoke sense; or, many smokers are smoking in the same room, This may cause an alarm. This JTY-GD-802 smoke-independent European CE certification is a hot product for domestic sales.

How often do you need to install a smoke alarm?
General families, Internet cafes, dormitories, and other small places need to have at least one set of smoke alarms installed. The specific number is determined by two factors. The number of dwellings and the number of bedrooms. An independent smoke protection space is about 30 square meters (empty), and the inclination of smoke installation cannot exceed 45 degrees. The following suggestions are based on the standards for home fire alarms published by the National Fire Protection Association of the United States:
1. For newly built homes, the standard requires a smoke alarm installed in each bedroom.
2. Install one outside the bedroom and across the door to hear the alarm.
3. Install at least one floor in the house.
4. It is necessary to install an alarm in each bedroom. There are many fires that occur in the bedroom. The closer the alarm is to the fire, the more likely it is to have an alarm.
5. The purpose of installing a smoke alarm outside the bedroom is to remind the sleeping person of a fire outside the bedroom. If the bedroom is located in different locations in the house, smoke alarms should be installed in different places.
6. If the house is large, more than one smoke alarm can be installed on different floors.
Smoke alarms are found through smoke, and the closer they are to fire, the quicker they can respond. Therefore, installing more smoke alarms will increase your security.
How to install an independent automatic smoke alarm JTY-GD-802?
Two 6 mm diameter mounting holes are made at a distance of 60 mm from the ceiling, and the bottom plate of the detector is fixed with plastic expansion tubes and screws. Rotate the detector counterclockwise, remove the base, and mark the polarity of the battery buckle on the 9V layered battery. Press the battery tightly, and then press the battery snap wire and battery into the battery compartment on the bottom of the detector. Note: If the battery is reversed, the detector will not work properly and it may damage the detector. Rotate the detector clockwise on the base and hold it in place. Hold down the self-test button. The detector indicator flashes rapidly and sounds an alarm. The alarm is working properly. If not, check whether the battery is installed correctly or the voltage is too low (7.5V). After the detector has been tested, the detector is snapped onto the base plate and tightened clockwise in place. An independent smoke protection space is about 30 square meters (empty), and the inclination of smoke installation cannot exceed 45 degrees.
What methods can we use to detect smoke detectors?
Each smoke alarm has a check button after it is produced. It is recommended that you always check your alarm regularly, at least once a month. Simulation test: You can light a cigarette, and then gently spray a few smoke into the smoke detector, the normal smoke sense After the smoke is detected, the alarm light starts flashing, and then emit an alarm sound. When the smoke has cleared, the smoke sense recovers.
Smoke alarm battery can be used for at least one year in normal circumstances. When the battery runs out quickly, it will sound intermittently at regular intervals. Some people also think this is a false positive. But this sound is very different because it sends a single, short sound. If your alarm sounds intermittently, you can replace the battery to see if it solves the problem. The biggest reason for smoke alarms to stop working is due to artificially removed batteries ----
How can we reduce the false alarms of smoke detectors?
False positives are a serious problem. When the fire does not happen, the smoke alarm constantly alerts you and you may withdraw it, so that when the fire does occur, no alarm will be issued.
The reasons for false positives are sorted as follows: 1. Cooking 2 Effects of steam or moisture 3 Smoke from smoking 4 Power 5 Dust Therefore, it is important to note that smoke should not be installed in the following places: places where smoke is trapped under normal conditions; Large dust, water mist, steam, oil mist, and corrosive gas.
Precautions:
The detectors should be installed in a kitchen or other place away from the places where flammable smoke particles are often produced, kitchens; garages with flammable exhaust gas produced by cars; locations close to stoves, water heaters or gas and heating. Extremely wet or near the bathroom with shower head. Because the humid air will enter the labyrinth to produce water vapor, the formation of condensation after cooling leads to false alarms.
Dust-prone areas: Dust can build up in the labyrinth of the detector to make it too sensitive, or it can block the detector's opening and prevent it from sensing smoke.
Close to the new wind entrance or the location where the wind speed is too fast: Air-conditioning, heating, fans, and fresh air will blow away the smoke and affect its detection.
Location close to fluorescent lamps: The detector should be installed at a distance of at least 1.5m from the lamp.
