Where fit to install smoke detector
1. First, you need to install at least one item in each
bedroom and route.
2. When a fire breaks out, the stairs are important for
you to rush out, so you must install a smoke detector
on top of the stairs.
45.5mm
3. At least one smoke detector is required for each
26.8mm
space on each floor, including the finished attic and
basement.
4. Install a detector next to each electrical facility.
You'd better install a smoke detector in the middle of
the ceiling because the smoke will always spread.
6. If for some reason you are unable to install it in the
middle of the ceiling, you will also need to install them
at least 10 cm from the wall.
7. If you want to mount them on the wall, install them
10-30.5 cm below the ceiling. figure 1.
8. When your hall is more than 9 meters long, you need
to install multiple detectors.
9. In a sloping roof room, install an alarm that is 0.9
meters from the top. figure 2.

chamber.

305mm. Electrical "noise" can interfere with the sensor.
