5. Maintenance
The working life of the detector is 5 years from power on, replace the device if you observe
Invalid indicator blinks.
The newly decorated or re-decorated room should be ventilated for some time before
installing the detector.
It’s suggested to press the Test button to check the LED indicators, buzzer and outputs
every month; besides, check if the device is online and send periodic status on the IoT
platform.
To ensure the air inlets are not blocked, wipe the device with a clean dry cloth, do not use a
very wet cloth, alcohol, harsh chemicals or detergents which may damage the detector.
Do not use a lighter or other gas to test the detector, which may damage the detector.
There is possible accuracy drift if you store without power for a long time in different
devices. If you prefer a more consistent reading with better precision, you can keep the
device powered on in clear air for some time according to the below list.
