2.6. Air Conditioning (Direct Systems VRF/VRV)
For compliance with EN378, at least one detector shall be installed in
each occupied space being considered and the location of detectors
shall be chosen in relation to the refrigerant and they shall be located
where the refrigerant from the leak will collect. In this case refrigerants
are heavier than air and detectors should have their sensors mounted
low, e.g., at less than bed height in the case of an hotel or other similar
Category Class A spaces. Ceilings or other voids if not sealed are part of
the occupied space.
CAUTION:
Monitoring ceiling voids in a hotel room would
not strictly comply with EN378.

[200 and 500 mm] off the floor).
…under mirrors.
…away from drafts and heat sources like
radiators, etc.
…at vanity units.
