Modalità per il corretto montaggio
3.1
Correct positioning mode
Il rivelatore deve sempre essere installato con l’elemento
sensibile (testa di rivelazione) rivolta verso il basso ad
esclusione delle versioni con sensore POP, POP-LS e
COP. Il contenitore del rivelatore, per nessuna ragione
deve essere forato; per il fissaggio utilizzare i fori già
esistenti.
I rivelatori sono forniti completi di staffa per fissaggio a
muro.
The gas detector is always to be mounted with the
sensing element placed downward (exluded versions with
POP, COP and POP-LS).
For no reasons at all the enclosure can be drilled.
Wall mount the detectors by employing the existing holes.
Detectors come complete with wall fixing brackets.
