erminating the wiring
This will not be a problem with new or
good condition ceilings, but beware of
old or cracked ceilings. Also ensure that
if the relevant building regulations call
for the ceiling speakers to be boxed-in or
fi tted with a fi reproof cover, that this is
adhered to. This is sometimes required to
maintain the integrity of the fi re rating of
the ceiling.
2.3 Cutting holes for ceiling
speakers
Once the correct centre hole has been
established, check that the position of this
is complementary to any existing ceiling
fi ttings and aligned with the other speaker
that makes up the pair. Use this hole to
centre the supplied speaker hole cut-out
template. Use the template to draw the
195mm hole cut-out.
Now drill a hole of about 6 to 8mm just
inside the outer circle. This will enable
the saw to be inserted to start cutting the
hole. Cut the hole carefully and slowly to
avoid chipping the plaster off the ceiling.
The fl ange of the ceiling speaker bezel will
cover any slight imperfections around the
hole itself.
2.4 Connecting the active
(right-channel) ceiling
speaker
Important:
Take the utmost care to ensure
that all wiring termination is correct. Errors
are unlikely to damage the Systemline
Modular system, but they will of course
result in it not working. Time spent here
can save much more time later.
Once the hole has been cut, release all of
the CAT5/6 cables from the ceiling cavity
and just leave them hanging down. Using
a small pair of steps (step ladder), place
the SLM2 speaker face down on the top
step (using a suitable material placed
on the step platform to protect the front
surface of the speaker).
There will normally be between four to six
CAT5/6 cables marked as follows:
• Zone name (eg kitchen)
• Spare + Zone name
• Keypad
• Left speaker
• There may also be a cable marked Local
• There may also be a cable marked Zone
name + Sub-zone out
Note:
Each of these cables will require the
outer sleeve to be cut back by about
40mm (1.5"). Do not strip the inner
conductors. A 110 tool will be required for
punch down termination. Do not use any
other method.
