2.2. Air Conditioning (Direct Systems VRF/VRV)
To ensure compliance with EN378 at least one detector should be
installed in each occupied space being considered. 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 a hotel or other
similar Category Class A space. Ceiling voids 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.
Do Mount In-Room Sensors…
Don’t Mount Sensors…
…at less than the normal heights of the
occupants. E.g., in a hotel room this is
less than bed height (between 100 and
300 mm [4 and 12 inches] off the floor).
…under mirrors.
…away from drafts and heat sources like
radiators, etc.
…at vanity units.
… to avoid sources of steam.
…in or near bathrooms.
IMPORTANT:
Carefully consider ramifications of using too few
sensors. A few extra sensors could make a significant
difference if a gas leak occurs.
