Most manufacturers call for a clear space of 500 mm for the beam away from obstructions; this is especially important for reflective type beam detectors.

It is easier to mount the detector on the beams than to mount them on the roof. What happens if the smoke misses the detector on the way to the ceiling? The fire must grow to a very big size to fill the roof down to the detector level before it can operate. We have lost the purpose of fire detection. i.e. early warning.

Smoke detectors provide the earliest means of fire detection and should always be considered before heat detectors for fire detection.
There are environmental conditions such as dust and humidity that present complications for smoke detectors. However, heat detectors tend to be immune to these conditions and can then be used as an alternative.
