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 8-21 Function commissioning
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.
