| WHERE TO INSTALL SMOKE ALARMS
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.
Install it in the stairway, because stairway take an important part
in emergent situation.
At least install one alarm in every floor.
Install one alarm beside the electric appliances in every room. Smoke,
heat and burning things will spread horizontally after rising to the
ceiling, so install one alarm in the middle of the ceiling of ordinary
structure house. Let the alarm can induce every corner.
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
beyond 10CM.
If install alarm on the wall, it should be 10~30.5CM below the
ceiling. (Like the diagram 1)
If the length of the room or the hall is beyond 9m, you need
install several alarms in the hall.
Alarm need be installed 0.9m away from the highest point in
room which is gradient. (Like the diagram 2)
* How to install alarm in moving room.
The moving room’s heat insulation is poor comparing with
ordinary structure room’s, 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.
If you don't know the moving room's heat insulation, install
one alarm on the wall. From the minimum safety, install one
alarm in the bedroom at least.
