2.2  Locating the speaker 

positions in each zone

Unless the cables for the ceiling speakers 
have been left hanging out of the ceiling 
(as is common with light fi ttings), it will 
be necessary to locate these positions. 
The easiest way is to refer to the marked-
up position of the speakers in the plan of 
the home. This should have been done as 
part of the fi rst fi x installation. If that is not 
the case, the following method should be 
used to trace the position of the cables.

Locating concealed  cables

A Cable Tone Test set, available from 
electrical wholesalers, can be used to 
locate concealed cables. 

Connect the tone generator to the cable 
being tested at the hub location (noting 
the correct label for a given room; see 

Wiring schedule

 in the

 Systemline 

Planning Guide),

 and move the probe 

over the ceiling of the selected zone room 
until the tone reaches its peak sound level. 
The cable should be directly above the 
plasterboard at this point.

Note:

 The above cable tracing technique 

will not work with foil-screened stud 
walling, metal wall tiles or ceiling panels.

It is recommended that you tackle one 
zone room at a time.

Once the speaker positions have been 
located and marked on the ceiling by 
way of a cross, check the following 
considerations. Remember also, that 
for some small rooms such as ensuite 
bathrooms, only a single mono speaker 
may have been provided for.

Clearance 

Drill a small diameter hole in the ceiling at 
the marked point and check, using a thin 
screwdriver or thin rod as a measuring 
tool, that there is at least 90mm depth 
from the front surface of the ceiling to the 
back.

In the very rare instance that there is 
insuffi cient depth, the speakers can be 
mounted protruding below the ceiling 
using a suitable spacer. For more 

information contact QED Audio Products 
Ltd.

Beware of joists

Make up an L-shaped test probe using stiff 
metal wire or a bent screwdriver. Check 
that there is suffi cient clearance to cut the 
correct diameter hole out of the ceiling. If 
during this test the L-shaped probe hits a 
joist, drill a second hole close to the fi rst 
one, but over to one side away from the 
joist.

Note:

 At this point you should be able to 

detect the presence of the CAT5/6 cables 
(indeed, these may interfere with your 
ability to spin the L-shaped tool around). 

Repeat the test to confi rm clearance.

L-shaped probe dimensions:

100mm (3.75")

L-shaped probe is obstructed by the joist:

Probe confi rms that by using the revised 
centre hole, that the 195mm dia hole can 
be cut without hitting the joist:

Once the correct position has been 
identifi ed, use the template provided and 
mark in pencil the correct 195mm (7.75") 
diameter hole on the ceiling.

Warning:

 Please ensure that the ceiling 

can withstand the weight of the speakers.
