Where to install Smoke Alarm:

1) At first, you need to install them in your bedroom and routeway, and should install at least one item in every bedroom.  

2) Stairway is important for you to rush out when fires occur, so smoke detectors must be installed there as Diagram 1 shows.

3) You at least require one smoke alarm on every floor, including finished attics and basements.Install one alarm beside every electric facility.

4) Install smoke alarms in the middle of ceiling, because smog, heat and flashes are always through the roof of rooms.

5) If some reasons cause you can’t install them in  the middle of ceiling, you need to install them at least 10cm away from the wall.

6) If you like to install them on the wall, they should be installed 10-30.5cm away under the ceiling as Diagram 2 shows.

7) You need to install more than one alarm when the length of your hall exceeds 9m.

8) In a triangle roof room, install the alarm 0.9m away from the top as Diagram 3 shows.

9) How to install smoke alarms in a removable house. The removable house is short of heat isolation, so you’d better install the alarm 10-30.5cm away from the ceiling. For safety you also need install another one near your bedroom

How to test the Smoke Alarm:

1) It is important to test this unit weekly to make sure it is working properly. Don’t open the alarms by yourself, return them to the seller if convenient, and don’t use fire to test your alarms,press the test button on the cover of the unit until the alarm sounds. If it does not alarm, make sure that the unit is receiving power and test it again. If it still does not alarm, replace it immediately or check your battery.

2) The signal flashes once every30 seconds and while it alarms the signal will flash once 0.5 per second.

3) If the alarm makes low “chirp” sounds about every 30seconds,it tells you to exchange your battery.

4) Little smoke will not cause alarms, so misinformation occurs only when you blow smoke to the alarms directly or you forget to turn on your ventilated facility while you are cooking.

5) Sometimes when you smoke the unit will alarm, so you can just blow air to it to stop alarming.
