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.
3. At least one smoke detector is required for each
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.
10. How to install a smoke detector in a detachable
house. The mobile house lacks insulation, so you'll
better install the detector 10-30.5 cm from the ceiling.

often exist, such as: kitchen, garage (exhaust gas),
stove, water heater or near the oiler.
3. In a humid or humid place; or near a bathroom with
a shower.
4. In a dusty, dirty or greasy place.
5. In very ventilated areas, the smoke will blow away
completely from the unit.
6. In the air recording area, this will block the sensing
chamber.
7. The distance from the fluorescent lamp is less than
305mm. Electrical “noise” can interfere with the sensor.
8. In the "dead air" space, for example, in Figure 1, less
than 10 cm near the corner.

power the system. After the power supply, allow the 80
second detector to work stably and then test it as
follows;
1. Switch the power, the indicator should flash once

pin is used correctly.
4. Smoke test: Take a smoldering wooden stick or
cotton core on the side of the detector and blow the
smoke into the detector until the alarm.
