How to install smoke alarm？

1.First of all, we should determine the specific location of the installation of smoke alarm. Generally, the smoke alarm is installed 3 meters away from the kitchen, so that the possible danger can be sensed in time. Then determine if the installation site is safe and avoid nearby cables and pipes. Then start to install its bracket, the back and the wall should be close to the bracket, and then open the smoke alarm box, look at the arrow inside, and then take off the smoke alarm.
2.Next, open the cover of the alarm, find the battery installation area to install the battery, press the port on the battery background above, at this time the alarm light will keep flashing, and then long press the black button to check whether the alarm works normally, if there is no abnormal situation, we can put the base and its shell all installed on the bracket.

3.After the installation of the alarm, we should carefully check whether the installation is firm, so as to avoid danger later. If the alarm is not very firm, be sure to use a screwdriver to tighten it, and install the screws, bolts to completely fix the alarm can be used normally.
