2.5. 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 a 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.
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 8 and 20
inches [200 and 500 mm] 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.
2.6. Remote Sensor Head Installation
If you do not wish to surface mount the MGS-350, a brushed stainless
steel faceplate is available. The remote sensor is mounted in an
electrical box 1.7 in (44 mm) deep to which the vented faceplate is fitted.
CAUTION: To avoid component mix-up, do not remove
sensor boards from multiple units at the same time.
Alternatively, label them, or match the serial number on the
main PCB and the remote sensor PCB when reinstalling.
1. Remove the connector from the sensor PCB to feed the cable
through the housing.
2. Immediately refit the connector to the sensor board in the back of the
box. The MGS-350 and remote sensor must be kept together as they
are calibrated together and are a matched pair.
