The ARU module:
This module was designed for switching between 2 signals (background music and Paging). There
are 4, 8 and 16 channel modules.
The ARU module was made very flexible. For example: it’s possible to use separate music sources
for each zone, or to use 1 common music source for all Paging Zones. All combinations in
between are possible. The connections which have to be made for this can be done in a very
simple way by setting “jumpers”.
In case of large installations, the ARU modules can be placed in cascade and addressed by the
Configuration Software.
The ARU module is suitable for mounting on a DIN-rail. On one side you have the “fixed
connections” (e.g. Amplifiers, …). On the other side you have the “field connections” (e.g.
Loudspeaker cables, CAT5 bus cable,…). This way of working allows a quick, proper cabling of
the system.
The AVD module:
This module was designed for switching 1 common signal to the output. There are 4, 8 and 16
channel modules.
The AVD module can be used for the following purposes:
-
Activating the “Emergency Call” relay on a classic volume control. In this case, we’re going
to switch 24V DC.
-
Activating power relays or teleruptors to trigger e.g. window blinds, door contacts, ...
-
Power on delay: In case of heavy equipment where the turn-on current is too large (e.g. 8
amplifiers of 4000 Watts), you can switch them on in cascade. The delay time is adjustable
by a small trimmer on the AVD unit.
In case of large installations, the ARU modules can be placed in cascade and addressed by the
