System With One Transmitter - Bosch INTEGRUS User Manual

INTEGRUS
To compensate the signal delay differences, you can increase the delay of each radiator. Set
these signal delays with the delay switches at the back of the radiator.
To determine the cable signal, you can:
–
–
In both cases, the cable signal delays can be calculated manually and with the delay switch
calculation tool available at www.boschsecurity.com.
It is not necessary to calculate the cable signal delay when:
–
–
In these cases, set the delay switches on all radiators to zero and determine whether to
compensate for radiation signal delay. See section Systems with more than 4 carriers and a
radiator under a balcony, page 50 .
The next sections describe how to calculate the delay switch positions manually for systems
with one transmitter, or two or more transmitters. See the delay switch calculation tool for
the procedures on how to calculate the delay switch positions automatically.
Warning!
The calculation tool to measure the delay switch eases the calculation of the delay switch

System with one transmitter

There are two ways to determine the delay switch positions:
–
–
Both methods are described in the next sections.
Notice!
i
For systems with a cable length difference of more than 50 meters, it is recommended to use
a measurement tool to determine the delay differences in order to calculate the delay switch
positions.
Determining delay switch positions by measuring the cable lengths
Use the following procedure to determine the delay switch position based on cable lengths:
1.
2.
Bosch Security Systems B.V.
Measure the cable lengths, or
Measure the impulse response time with a delay measurement tool.
The radiators are directly connected to the transmitter with an equal cable length
The radiators are connected in a loop, but with less than 5 m distance between the first
and last radiator in a trunk, and with an equal cable length between the first radiator in
each trunk and the transmitter.

Measuring the cable lengths
Using a delay measuring tool
Look up the cable signal delay per meter of the used cable. The manufacturer specifies
this factor.
Measure the lengths of the cables between the transmitter and each radiator.
