If multiple multi-functional sensors are connected, commission one multi-functional sensor first and
then commission the other multi-functional sensors in the same way.
Step 2 Check the functions of the multi-functional sensor.
Table 8-17 Function check
Check Method
Normal Connection Status
Temperature and humidity
detection: View the running
information about the
multi-functional sensor on the
WebUI.
You can view the current ambient temperature and
humidity.
Smoke detection: Simulate a
smoky environment.
Smoke generation methods:
Generate smoke. Place the paper
5–10 cm away from the smoke
compartment, and let smoke
enter the smoke compartment
through the hole in the side of
the multi-functional sensor.
Smoke dispersing method: Send
clean air to the smoke
compartment through the hole in
the side of the multi-functional
sensor.
CAUTION

Do not generate open flame, and
ensure that smoke does not
damage any device.

When testing the smoke
detection function of the
multi-functional sensor, do not
start the smart cooling product
or fan, because the air from the
smart cooling product or fan
will interfere with the smoke,
and therefore affect the
detection result.

After the commissioning is
complete, clean up dust.

Start counting time immediately when smoke is
entering the hole. After about 30 seconds, the red
ALM indicator turns on, and the app or WebUI
displays a smoke alarm.

Some time later after the smoke is dispersed, the red
ALM indicator turns off and the smoke alarm
disappears.
