Installation:                                                                                                                                                                             choose a suitable installation area                                                                                      

- choose a suitable installation area

- drill two holes on the ceiling or wall as the bracket site

-drill according the bracket pore range

-put two plastic loin pin, then stick the bracket on the wall

-plug and fix it  still the bracket in  firm .

-don't open the detector, it is a hermetic set, only fill the battery in to the backspace 

put the detector back against the bracket site, and revolve in sequential time, make sure the screw into the loin pin.

-press  the test  to test the detector is normal or not
