Device set-up
8.1
General
Caution
Do not put objects on top of devices. Objects
can fall through the airflow holes. A blockage of
the airflow holes can cause a risk of fire.
8.4
•
•
•
Make sure that the area is clean.
Make sure that the air is sufficiently cool.
Make sure that there is sufficient lighting.
8.2
Cables
Use different cable ducts for the extension and mains
cables. Identify each cable with a label and divide
trunks to manageable geographic locations. In public
areas where people can touch or move above the
connectors and cables, use metal protection covers.
Refer to the applicable protection specification of the
protection covers.
8.3
Temperature
When devices are in a 19-inch rack, make sure there is
rack space between the devices to let sufficient air flow.
Forced airflow may be necessary to keep the
temperature of the devices below the maximum
temperature (refer to section 9.2). This extends the
lifetime of the devices.
Bosch Security Systems | 2007-02 | 9922 141 70691 en
Ventilation
Keep a good airflow. Airflow holes are in the front, right
and left sides of all 19-inch devices (for example, the
central control unit and the audio expander).
• Put the devices on a hard and level surface.
• Put the central control unit at minimum distance of
0.10 m from walls to let sufficient air flow.
8.5
Cleaning
Caution
Do not use alcohol, ammonia or petroleum
solvents or abrasive cleaners to clean the
devices.
Caution
Do not put the devices near or above a radiator,
heat grill or in direct sunlight.
Caution
Do not cause vibration of the devices.

Acoustic feedback
Acoustic feedback (‘howling’) occurs when the sound of
the loudspeakers or headphones in the system is sent to
the system again by activated microphones.
table 8.1: Acoustic feedback
Source
The acoustic feedback is caused by
the loudspeakers of the contribution
devices.
Quick solution
Decrease the volume level of the
system. For example, with the knob
on the front of the central control
unit (refer to section 10.6.3).
Structural solution
Do as follows:
1 Install a feedback suppressor
between audio input 2 and audio
output 2 of the central control
unit.
2 Set the audio routing mode of
the system to Insertion (refer to
section 12.6).
The acoustic feedback is caused by
an external public address system
that is connected to the DCN
Wireless digital congress network.
Decrease the volume level of the
public address system or the DCN
Wireless digital congress network.
Install a feedback suppressor
between audio output 1 and the
input of the external public address
system.
The acoustic feedback is caused by
the headphones that are connected
to the contribution devices.
Tell the chairmen and the delegates
to decrease the volume level of their
headphones with their contribution
devices.
Install and configure the
headphones level reduction of the
contribution devices. (Refer to the
section about the contribution
devices.)
