How many square meters should a smoke alarm be installed?
1. When the indoor floor height is between six meters and twelve meters, one should be installed every eighty square meters.
2. When the indoor floor height is below six meters, one should be installed every fifty square meters.
Note: The specific interval of how many square meters a smoke alarm should be installed generally depends on the indoor floor height. Different indoor floor heights will result in different intervals for installing smoke alarms.
Under normal circumstances, the radius of a smoke alarm that can play a good sensing role is about eight meters. For this reason, it is best to install a smoke alarm every seven meters, and the distance between smoke alarms should be within fifteen meters, and the distance between smoke alarms and walls should be within seven meters.
What details should be paid attention to when installing a photoelectric smoke alarm?
1.Before installation, be sure to determine the correct installation position of the smoke alarm. If the installation position is incorrect, the use effect of the smoke alarm will be worse. Under normal circumstances, the smoke alarm should be installed in the middle of the ceiling.
2. When wiring the smoke alarm, do not connect the wires in reverse, otherwise the smoke alarm will not work properly. After installation, a simulation experiment should be conducted to ensure that the smoke alarm can be used normally.
3. In order to ensure that the smoke alarm can be used normally and prevent the accuracy of the smoke alarm from being affected by the dust accumulated on the surface, the dust cover on the surface of the smoke alarm should be removed after the smoke alarm is officially put into use.
4. The smoke alarm is very sensitive to smoke, so smoke alarms cannot be installed in kitchens, smoking areas and other places. In addition, smoke alarms cannot be installed in places where water mist, water vapor, dust and other places are prone to occur, otherwise it is easy to misjudge the alarm.
Installation
1. Install a smoke sensor for every 25-40 square meters in the room, and install smoke sensors 0.5-2.5 meters above important equipment.
2. Choose a suitable installation area and fix the base with screws, connect the smoke sensor wires and screw them on the fixed base.
3. Draw two holes on the ceiling or wall according to the holes of the mounting bracket.
4. Insert two plastic waist nails into the two holes, and then press the back of the mounting bracket against the wall.
5. Insert and tighten the mounting screws until the mounting bracket is firmly pulled out.
6. This smoke detector is a closed device and is not allowed to be opened. Please insert the battery into the compartment on the back of the unit.
7. Put the back of the detector against the installation position and turn it clockwise. And make sure that the two screw heads have slid into the waist-shaped holes.
8. Gently press the test button to see if the detector is working properly.
Precautions for installation and maintenance of smoke detectors
1. Do not install it on a floor with high temperature and high humidity, otherwise it will affect the sensitivity.
2. To keep the sensor working efficiently, clean the sensor every 6 months. First turn off the power, then use a soft brush to lightly sweep the dust, and then turn on the power.
3. The detector is suitable for places where there is a lot of smoke when a fire occurs, but there is no smoke under normal circumstances, such as: restaurants, hotels, teaching buildings, office buildings, computer rooms, communication rooms, bookstores and archives and other industrial and civil buildings. However, it is not suitable for places where there is a large amount of dust or water mist; it is not suitable for places where steam and oil mist may be generated; it is not suitable for places where smoke is trapped under normal circumstances.
