What would trigger false alarm into smoke detectors?

Since our smoke detectors are newly installed in the entire 638-640 rue Pouliot complex, which are powered by 10-year batteries. There aren' t issues on dead batteries issue. 
There would be following reasons on why would trigger false alarms inside apartment units, as per our study. 
1, High Humidity and Smoke Detectors: High humidity can sometimes trigger false alarms in our smoke detectors. 
The dense moisture particles in humid air could be mistaken for smoke particles by the detector. 
In extreme cases, the air density can even scatter the light beam of a photoelectric sensor or cling onto the ions in an ionization chamber.
To keep air circulation inside our apartments and to maintain optimal smoke detector performance and to prevent false alarm alerts, we recommend our residents proceed the following:

• Turn off humidifiers when not needed, or turn down water vapors.
• Open windows periodically for fresh air circulation, in the unit.

2. Dust Buildup: A buildup of dust can also affect the performance of smoke alarms to trigger false alarms. 
To prevent this, we recommend our residents cleaning smoke detectors at least once a year using your vacuum brush attachment. 
Regular maintenance ensures that the sensors remain sensitive and accurate within units.

We continue to work together with our residents to prioritize safety within our community.
