Mounting instructions
1 The ideal mounting height for
door loudspeaker units lies between
1,40 m/4,6 ft and 1,60 m/5,25 ft
above the height of the finished
floor.
Surface mounting, vertical or
horizontal
2 f the plaster is highly uneven,
additionally glue the four provided
distance washers on the back panel
of the surface mount housing
GA 612-... over the screw holes on
the already mounted washers (a).
Open the cable entry (b) at the
required position and glue the
provided water deflector (c) like a
roof on the back panel.
Cable entries which are not required
must remain closed.
3 Strip the connecting cable of its
sheathing to max. 3 cm/1,2 inch,
insert through the back panel into
the GA 612-... and fasten the
housing on the wall. Pay attention to
the indication „top".
4 In order to prevent material
fatigue of the catch lugs, ensure
that they are not pushed backwards
but correctly locked in position. If
necessary, release these using a
small screwdriver.
5 Remove the combination terminal
strip from the module packaging,
centre on the retaining plate turned
by around 45° to the left, and lock
into position with a quarter turn in
the clockwise direction so that the
terminal designations are legible
vertically one above the other.
6 Press the connecting cables with
the cable holding-down devices onto
the floor of the housing. In the case
of multiple-row units, fix the
connecting wires using the wire
holding brackets. Connect the unit
using the relevant circuit diagram at
the combination terminal strip.
7 Insert the mounting frame in such
a way that the sealing film is located
at the upper and right-hand edge of
the mounting frame. When
positioned horizontally, multiple-row
housings must always be fitted from
bottom to top, so ensuring that the
4
sealing film of the lower mounting
frame overlaps that of the lower
frame in fish-scale formation. When
mounting vertically, ensure that the
lateral film is positioned under the
adjacent mounting frame. Clip the
mounting frames in the surface
mount housing using a light
pressure.
Catch lugs which are not required
can be pressed out of the surface
mount housing with a screwdriver
and moved if required.
8 The mounting frame can be
removed from the GA 612-... by
pressing back the catches.
Note! Turning back can cause the
catches to become locked in
position. (see Fig. 4)
Flush mounting
9 Position flush mounting housings
GU 611-... next to each other and
connect using the provided
connectors. These connectors are
mounted on a pin in the GU 611-...
together with the cable holding-
down device as injection moulded
parts. The connectors can be broken
off by a twisting action.
10 For combination frames bigger
than 300 x 300 mm, the corners of
the GU 611-... must be broken out.
For in-row mounting involving a
large number of units, specially
produced combination frames are
required.
11 (Not illustrated)
Break out the cable gland between
the housing units.
12 Plaster in the horizontal or
vertical GU 611-... and insert the
provided cardboard into the
GU 611-... This serves as a plaster
protection and for reinforcement
and remains in the housing until
final assembly. Up to a maximum of
15 mm/0,6 inch plaster height
difference can be compensated.
13 Remove the combination
terminal strip from the module
packaging, centre on the retaining
plate turned appr. 45° to the left
and lock into position with a quarter
turn in the clockwise direction so
that the terminal designations are
legible vertically one above the
other.
14 If combination frames of 600 X
500 mm/23,6 inch x 19,7 inch and
bigger are used, a cross is created in
the substructure of the peripheral
frame. There is an adjusting screw
let into this cross, which allows the
substructure to be supported away
from the flush mount housing. Turn
the adjusting screw inwards until the
substructure is positioned parallel to
the front. This guarantees that the
front of the inserted module is
correctly aligned.
15 Strip the connecting cables of
their sheathing, press onto the floor
of the housing, fix using the cable
holding-down devices and connect
the unit in accordance with the
relevant circuit diagram at the
combination terminal strip.
16 Insert the mounting frame
together with the combination
frame in such a way that the sealing
profile of the combination frame is
open towards the bottom. The
mounting frame must be inserted in
such a way that the sealing film is
located at the upper and right-hand
edge of the mounting frame. When
positioned horizontally, multiple-row
housings must always be fitted from
bottom to top, so ensuring that the
sealing film of the lower mounting
frame overlaps that of the lower
frame in fish-scale formation. When
mounting vertically, ensure that the
lateral film is positioned under the
adjacent mounting frame. Clip the
mounting frames in the surface
mount housing using a light
pressure.
17 Press the combination frame
together with the mounting frame
completely against the wall and
screw in the flush mount housing
using the provided quick-locking
screws, turning a quarter turn to the
right (until the stop).
Hollow wall mounting
18 Trace the cut-out for the flush-
mount housing GU 611-... To do
this, lay the provided cardboard
template flat on the wall and draw
