1. How many square meters to install a smoke alarm

1.1 When the indoor floor height is between six meters and twelve meters, one should be installed at an interval of 80 square meters.

1.2 When the indoor floor height is less than six meters, one should be installed every 50 square meters.

Note: The smoke alarm should be installed at a specific interval. Generally, it depends on the indoor floor height. The indoor floor height is different, and the interval area for installing smoke alarms will also be different.

Under normal circumstances, the radius of the smoke alarm that can play a good sensing role is about eight meters. For this reason, it is best to install a smoke alarm at an interval of about seven meters, and the distance between the smoke alarms is best. Within fifteen meters, the distance from the wall is preferably within seven meters.


2.what details should be paid attention to when installing smoke alarms

2.1 Before installation, you must first determine the correct installation position of the smoke alarm. If the installation position is not correct, it will lead to poor use of the smoke alarm. In general, smoke alarms should be installed in the middle of the ceiling.

2.2 When wiring the smoke alarm, do not connect the wires backwards, otherwise the smoke alarm will not work properly. After the installation is completed, a simulation experiment should be carried out to ensure that the smoke alarm can be used normally.

2.3 In order to ensure that the smoke alarm can be used normally and avoid the accuracy of the smoke alarm being affected by the dust accumulated on the surface, the dust cover on the surface of the smoke alarm should not be removed until the smoke alarm is officially put into use.

2.4 Smoke alarms are 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, etc. are easy to be generated. Otherwise, it is easy to cause misjudgment and alarm.


3.Smoke Detector Smoke Alarm Test

Press the test button for at least 3 seconds, a clear and loud pulsating alarm signal will be sent out.

This means that the detector is really working, and at the same time as the alarm, the LED flashes quickly.

The detector can also be tested by blowing smoke into the detection chamber. (do a test once a week to verify the reliable operation of the detector).


4.Precautions for installation and maintenance of smoke detectors

4.1 Do not install in places with higher temperature and high humidity, otherwise the sensitivity will be affected;

4.2In order to keep the sensor working efficiently, the sensor needs to be cleaned every 6 months. First turn off the power, then use a soft brush to sweep the dust, and then turn on the power.

The detector is suitable for places where there is a lot of smoke when a fire occurs, but there is no smoke under normal conditions, such as: restaurants, hotels, teaching buildings, office buildings, computer rooms, communication rooms, library and archives and other industrial and civil buildings. However, it is not suitable for places with a lot of dust and water mist; it is not suitable for places where steam and oil mist may be generated; it is not suitable for places with smoke under normal conditions.
