I have seen tradies attempt to ‘disable’ smoke particle detectors by putting tape or a rubber glove over the sensor. This technique often triggers the alarm almost immediately.
Commercial fire sensors do have plastic caps which block airflow without triggering an alarm. They’re designed to be kept on during construction until each sensor is commissioned.
