If smoke detectors are used in many spaces the use of aspirating systems could be considered instead of point smoke detectors. The benefit of this approach is that only one detector is needed and the system samples air from e.g., both the ceiling and other spaces in the toilet compartment. More advanced aspirating systems could potentially also sample air from different locations around the entire bus. An aspirating smoke detector in the toilet compartment ceiling also has a great advantage in that the detector is hidden and protected. According to the bus operators they have problems with passengers pulling down the detectors. Another important design consideration when installing detectors in the toilet compartment ceiling is the need to avoid the air flow from the air inlet.
