WR option (Weather Resistance)
A number of d&b loudspeakers are available in special options
suitable for different types of installed applications and
environmental conditions. The following options are available for
the B22-SUB loudspeaker:
▪ Sea water resistant (SWR): This option is suitable for outdoor
use, especially in wet and acid or salty environments.
WR cabinets are equipped with a recessed connector panel
including a Faston type connector (2 x 6.3 mm, female). A cover
plate which accepts single or dual PG cable glands (Type PG13.5
for cable diameters from 6 - 12 mm) is enclosed, as shown in the
graphic opposite.
NOTICE!
The WR option enables operation of loudspeakers in changing
ambient conditions, however it is not intended to enable
permanent, unprotected operation of loudspeakers outdoors.
▪ Provide an additional cover over the loudspeakers.
▪ Aim the cabinets either horizontally or with a downward tilt.
To install the fixed connection cable, please proceed as follows:
Tools required: Screw driver (#T20).
Note: Observe the correct polarity of the cable
Brown (+) / Blue (—).
1. Insert the connection cable through the PG screwing and
connect the male connector to the female connector.
2. Push the cover plate towards the connector panel until it fits
into place.
3. Fix the cover plate to the connector panel using the four
countersunk screws.
