10. Add delay switch positions to radiators
under a balcony, if applicable (see section
3.5.3)
Set the delay switches to the calculated delay
switch positions.
Figure 3.5-B and Table 3.5-2 illustrate the
calculation of the signal delays and the delay
switch positions.
Note The calculated delay switch positions based on
impulse response time can differ from the calculated
delay switch positions based on cable lengths. This is
caused by the accuracy of the measurements and the
accuracy of the cable signal delay factor per meter as
specified by the manufacturer of the cable. If the
impulse response time is measured correctly, the
calculated delay switch positions will be the most
accurate.

System with two or more

When radiators in one multi-purpose room are

transmitters in one room

connected to two transmitters, an extra signal
delay is added by:
Transmission from master transmitter to
slave transmitter (cable signal delay).

Transmission through the slave transmitter.
Use the following procedure to determine the

delay switch positions in a master-slave
configuration:

584/2 = 292
237/2 = 118
339/2 = 169

1. Calculate the cable signal delay for each
radiator, using the procedures for a system
with one transmitter.
2. Calculate the signal delay of the cable
between the
transmitter in the same way as for cables
between a transmitter and a radiator.
3. Add to the cable signal delay of the cable
between the master and the slave, the delay
of the slave transmitter itself: 33 ns. This
gives the master-to slave signal delay.
4. Add the master-to-slave signal delay to each
radiator connected to the slave transmitter.
5. Determine the maximum signal delay.
