Figure 4.17 Increased coverage area caused by added radiation power

Figure 4.18 Reduced coverage area caused by differences in cable signal delay

The lower the carrier frequency, the less susceptible the receiver is for differences in signal

delays. The signal delays can be compensated by using the delay compensation switches on

the radiators (see section 7.4 ).

Planning an Integrus infra-red radiation system

4.3.1

Determining the optimal number of infra-red radiators required to give 100% coverage of a

hall can normally only be done by performing a site test. However, a good estimation can be

made by using 'guaranteed rectangular footprints'. Figure 4.19 and Figure 4.20 show what is

meant by a rectangular footprint. As can be seen, the rectangular footprint is smaller than the

total footprint. Note that in Figure 4.20 the 'offset' X is negative because the radiator is

actually mounted beyond the horizontal point at which the rectangular footprint starts.
