Use the following procedure to plan the
3.4.2

Planning radiators

radiators:
1. Follow the recommendations in section 3.3
in order to determine the positioning of the
radiators.
2. Look up (in the table) or calculate (with the
Footprint Calculation
DIS_FCPv5.3_.xlt) the applicable rectangular
footprints.
3. Draw the rectangular footprints in the lay-
out of the room.
4. If the receiver can pick up the signal of two
adjacent radiators in some areas, determine
the overlap effect and draw the footprint
enlargement(s) in the lay-out of the room.
5. Check whether you have sufficient coverage
with the radiators at the intended positions.
6. If not so, add additional radiators to the
room.
See Figure 3.3-K, Figure 3.3-L and Figure 3.3-M
for examples of a radiator lay out.
Tip: The Footprint
DIS_FCPv5.3_.xlt eases the work planning radiator
coverage. The Program is to be found at the 'DCS 6000
Digital IR System User Manual CD'
Signal delay differences can occur due to
3.4.3

Cabling

differences in the cable length from the
transmitter to each radiator. In order to
minimize the risk of black spots, use equal cable
length from transmitter to radiator if possible
(see Figure 3.4-D). When radiators are loop-
through connected, the cabling between each
radiator and the transmitter should be as
symmetrical as possible (see Figure 3.4-E and
Figure 3.4-F). The differences in cable signal
delays can be compensated with the signal delay
compensation switches on the radiators.
