How to disarm the smoke alarm
1. The hole where the smoke alarm is installed on the bracket is located on the ceiling or wall. Lock the two holes according to their positions. Insert two plastic waist nails into the two holes, and then install the back of the mounting bracket on the wall. Insert and tighten the mounting screws until the mounting bracket is firmly removed from the bottom. To remove the smoke alarm, first unscrew the screws on the bracket, and then remove the plastic waist nails in the two holes, so that the smoke alarm is removed.
Second, the sub-base (fixed on the ceiling) and the main body (dripping part) are stuck together. You turn the main body around and then you pull it down.
Some people question: Is it useful to install a smoke alarm? With the increase of fire and electricity consumption in modern families, the frequency of family fires is getting higher and higher. Once a family fire breaks out, it is easy to appear unfavorable factors such as untimely fighting, lack of fire-fighting equipment, panic of people present, slow escape and so on, which will eventually lead to heavy losses of life and property. The main cause of family fire is carelessness and failure to take preventive measures in time. Smoke alarm is an inductive sensor used to detect smoke. Once there is a fire danger, the electronic speaker inside will remind people in time. So it is useful to install a smoke alarm.
"Smoke sense" is actually another name for smoke detector or smoke alarm, and the purpose of preventing fire is achieved by monitoring the concentration of smoke. Among them, ion smoke sensor is used, which is widely used in various fire alarm systems, and its performance is far better than that of gas-sensitive resistance fire alarm.
Independent smoke fire detection alarm can detect the early characteristics of fire, send out fire alarm signals, provide instructions for evacuation and escape, and prevent the spread of fire.
① There is no need to connect the fire alarm controller, and the battery is used for power supply, which is economical and practical.
② The built-in buzzer makes a strong sound after alarm.
③ Simple installation and no need of debugging.
(4) The power consumption is extremely small, and it can work for several years under normal circumstances.
It is an effective technical means to prevent and deal with fires in various places by giving an alarm directly after the fire is detected in the early stage to remind the on-site personnel to call the police quickly and evacuate in time.
① In the kitchen, it is recommended to install the smoke alarm 3 meters away from the cooker. In the sleeping area, install smoke alarm within 4 or 5 meters, so that everyone can hear the alarm, even if the bedroom door is closed.
② For single-storey houses, smoke alarms should be installed between corridors, sleeping areas and living areas. It is best to put it on the ceiling, at least 30 cm away from the wall or lamps.
(3) For large-sized houses or multi-storey houses, in addition to the installation position of the above-mentioned single-storey houses, the joint between the bottom of the stairs and the stairs of each floor should be added. At the same time, consider buying an interconnected alarm, so that the smoke or heat detected on one floor can trigger the alarm of the whole house.
No matter where the smoke alarm is located, don't install it on objects that will generate steam, otherwise it is easy to touch the alarm by mistake.
(1) First of all, find the best place to install the alarm, find out the location of hidden pipes and cables, and avoid making holes there.
② Remove the alarm cover and install the battery as needed.
③ Fix the chassis of the back cover of the smoke alarm on the wall or ceiling, and mark the screw points with a pointed cone or nail through hole.
④ Drill holes and install screws and bolts.
⑤ Tighten the smoke alarm in place, cover it and start the test.
When sleeping, the smoke alarm must be the first and possibly the only warning to the smoke generated by the fire, so the house must be equipped with a smoke alarm.
① When purchasing an independent smoke detector, ensure that it has passed CCC certification (compulsory product certification system) and obtained the product certification certificate.
② Don't install the alarm in a place with high temperature and heavy oil smoke, and keep its surrounding environment clean.
③ Please avoid using mousse, insecticide, thinner and other items that produce colloidal suspended matter near the alarm, so as not to affect the normal monitoring of the alarm.
(4) The alarm should be installed after indoor decoration to avoid alarm pollution.
⑤ Install an alarm near the fluorescent lamp at least 1.5m away from the lamp.
Please install the battery according to the product instructions. If unqualified batteries are used, the detector may be damaged.
I'll tell you so much about how to dismantle the smoke alarm first. According to statistics, only 5% families have installed smoke alarms at home, which is a great security risk. Smoke alarm can effectively monitor the initial fire and greatly improve the convenience and safety of life.
Smoke alarm problem description
How to prevent the smoke alarm from alarming;
Seal the smoke alarm with adhesive tape or plastic bag, and the smoke sensor can't receive smoke information;
When the buzzer is turned off, the alarm will not sound, which is not suitable for the linkage fire alarm system;
Dismantle the smoke alarm. The wireless independent smoke alarm can be removed if it is no longer needed.
Keeping the smoke alarm silent is not conducive to indoor fire safety, so try not to use it. It is worth mentioning that most smoke detectors are independent weak current systems, and it is impossible to make smoke detectors not work by cutting off the power supply in the room. At present, there are three kinds of smoke detectors (fireworks detectors) in China.
One: The bus intelligent smoke sensor and coded smoke sensor in the fire protection system have no buzzer, that is, there is no sound. After the alarm, the light will flash and the signal will be sent to the host.
Second, it is an independent smoke sensor, powered by a 9V battery. The smoke sensor must be equipped with a buzzer. When giving an alarm, there is sound and light at the scene, and it is not allowed to take the buzzer out of the independent smoke sensor.
Three: switch/relay smoke sensor (multi-line smoke sensor /4-line smoke sensor), mainly used for supporting security systems (anti-theft, monitoring, fire shutter system, etc.). ).
This kind of cigarette factory usually has a buzzer. If no sound is needed, you can ask the manufacturer to remove the buzzer. In fact, there is no buzzer when such products are exported. Personal operation to remove the buzzer sound needs to report the smoke, find the wiring of the buzzer and cut it off.
Causes of false alarm of smoke alarm
1. First of all, the smoke alarm is too sensitive. Generally, even if you smoke, there will be an early warning. In this case, we can remove the alarm and open the black part inside the alarm. We can wipe it a little, which can reduce the sensitivity of the smoke alarm.
2. The smoke alarm is not used all the year round, resulting in dust accumulation and falling into the sensor, thus giving an alarm. Of course, this situation is generally rare, but it still exists.
3. If the voltage is unstable, the alarm will also be electrified for transmission. If the voltage there is unstable, the sensor will slowly lose its activity and will give an alarm if something happens.
The smoke alarm will not give an alarm at will.
(1) If the smoke alarm is installed far away from cooking, the smoke particles will be much weaker when they reach the alarm. If you choose this method, you should know the direction of airflow. Otherwise, it will not work.
(2) Install photoelectric smoke alarm. When there is a fire that produces smaller particles, you may lose the opportunity to call the police earlier, but you also save the trouble of multiple smoke alarms failing.
That's all about how to disassemble the smoke alarm. Smoke alarm is a common fire alarm device, which can accurately sense the smoke produced by the fire at the initial stage of the fire and give people an alarm quickly.
