Attentions for installation:
Before you install the alarm, read the instruction carefully and keep it!!!

1. Where to install best
1.1 At first you need install one in the bedroom and route way, because the bedroom is far away from the exit usually, if you have several bedrooms, you’d better install one alarm in every room.

1.6 If alarm can’t be installed in the middle of the ceiling for some reasons, the distance the alarm away from the wall should be more than 10CM.
1.7 If install alarm on the wall, it should be 10~30.5CM below the ceiling. (Like the diagram 1)

1.9 Alarm need be installed 0.9m away from the highest point in room which is gradient. (Like the diagram 2)
1.10 How to install alarm in moving room. 
1.10.1 The moving room’s heat insulation is poor comparing with ordinary structure  room, the inner and outer energy exchange with cool air through very thin  wall and ceiling, so a heat insulation layer form easily near the wall and  ceiling, which baffle the smoke go to alarm. Installed in this structure room,  alarm need be 10~30.5cm below the ceiling. 
1.10.2 If you don’t know the moving room’s heat insulation, install one alarm on the  wall. For the minimum safety, install one alarm in the bedroom at least. 

2 Where not fit to install.

2.8 Near fluorometry lamp. 

3 Installation 
3.1 Turn the body of the alarm counterclockwise, take off the bottom plate.

3.2 Press the bottom plate on the installation position, mark installation hole of the plate with pencil. 
3.3 Bore two installation holes(ф6.5,height 35mm) on the sign with electric drill(6.5mm drill bit). 
3.4 Strike the dilatant into holes with hammer, screw the bolts(3X30) with gasket into the half of the dilatant, then hang the bottom plate on the screw(gasket press on the plate), tighten the screw. 

3.5 open the battery box, press the battery into box and button it. Without battery the box can’t be buttoned, in a general way there is not battery before the product is out of factory. Before using you should open the box and check.(like the following diagram)

3.3 test: if the alarm and the battery are normal, press the test button for 2 seconds, it will be in the testing state. If it don’t alarm, please check if the battery’s fixing is correct. if the fixing is correct, probably the alarm has some defect, please contact with the supply, do not open the alarm yourself, don’t test the alarm with fire. 
3.4 if there are repetitive and interim low voltage alarm “di”, the interim time is 30 seconds, it indicate the battery’s energy is shortage. To ensure normal alarm, please replace the battery. 

4 False alarm 
4.1 the design for the alarm has diminished false alarm to the minimum, a little smoke can’t lead it alarm generally, except whiffing it into alarm directly. In the kitchen if there is not vent-smoke device, it will lead false alarm when cooking,
