2.2 Mounting
Xsafe Bright
should be installed at the designated location with the sensor
pointing down. This ensures that dust or water will not collect on the sensor
and stop gas or solvents being measured entering the cell. Care should be
taken when installing the detector to avoid damaging the painted surface of
the enclosure. There are two M20x1.5 entry ports on the base. One entry port
will be used for power supply input during normal operation. Unused port will
be blocked by blind plug, or can be used to connect external alarm device or
be used for connecting devices to the multi-drop communications.
Note:
Please avoid direct water jets into the sensors, as it is likely to lead to
damage.
